NOTE: For a balanced 4-wire Wye system, the meter's calculations assume that there is no current flowing through the neutral conductor. Balanced 3-phase Wye system with 2 CTs The current for the unconnected current input is calculated so that the vector sum for all three phases equal zero. Balanced 3-phase Wye or Delta system with 1CT The currents for the unconnected current inputs are calculated so that their magnitude and phase angle are identical and equally distributed, and the vector sum for all three phase currents equal zero. NOTE: You must always use 3 CTs for 3-phase 4-wire center-tapped Delta or center-tapped open Delta systems. Serial communications The meter supports serial communications through the RS-485 port. Up to 32 devices can be connected on a single RS-485 bus. NHA2768503-05 17 Conzerv EM6400NG+ RS-485 wiring 18 Hardware references In an RS-485 network, there is one master device, typically an Ethernet to RS-485 gateway. It provides the means for RS-485 communications with multiple slave devices (for example, meters). For applications that require only one dedicated computer to communicate with the slave devices, an RS-232 to RS-485 converter can be used as the master device. Connect the devices on the RS-485 bus in a point-to-point configuration, with the (+) and (-) terminals from one device connected to the corresponding (+) and (-) terminals on the next device. C - - + + 120 NOTE: Straight-line topology only. Loop or ring topology is not supported. Resistor is an optional accessory that you can order separately. To terminate a series, it is recommended to use a 120 / 0.5 W resistor. RS-485 cable Use a shielded 2 wires or 1 twisted pair RS-485 cable to wire the devices. Use the twisted pair to connect the (+) and (-) terminals. RS-485 terminals C Common. This provides the voltage reference (zero volts) for the data plus and data minus signals Shield. Connect the bare wire to this terminal to help suppress signal noise that may be present. Ground the shield wiring at one end only (either at the master or the last slave device, but not both. - Data minus. This transmits/receives the inverting data signals. + Data plus. This transmits/receives the non-inverting data signals. NOTE: If some devices in your RS-485 network do not have the C terminal, use the bare wire in the RS-485 cable to connect the C terminal from the meter to the shield terminal on the devices that do not have the C terminal. RS-485 maximum cable length The total distance for devices connected on an RS-485 bus should not exceed 900 m (2953 ft). RS-485 network configuration After you have wired the RS-485 port and powered up the meter, you must configure the serial communications port in order to communicate with the meter. Each device on the same RS-485 communications bus must have a unique address and all connected devices must be set to the same protocol, baud rate, and parity (data format). NOTE: To communicate with the meter using ION Setup, you must set the serial site and all connected devices in the RS-485 network to the same parity setting. NHA2768503-05 Hardware references Pulse output Conzerv EM6400NG+ The meter is equipped with one pulse output port (D1+, D0-). You can configure the pulse outputs for use in the following application: � Energy pulsing applications, where a receiving device determines energy usage by counting the k_h pulses coming from the meter's pulse output port. One pulse output can handle voltage less than or equal to 40 V DC (20 mA maximum). For higher voltage applications, use an external relay in the switching circuit.

It is common practice to initialize the meter after its configuration is completed, before adding it to an energy management system. After configuring all the meter setup parameters, navigate through the different meter display screens and make sure the displayed data is valid then perform meter initialization. NOTE: You can perform meter initialization using ION setup and secured command interface. Real-time readings The meter measures currents and voltages, and reports in real time the RMS (Root Mean Squared) values for all three phases and neutral. The voltage and current inputs are continuously monitored at a sampling rate of 64 samples per cycle. This amount of resolution helps enable the meter to provide reliable measurements and calculated electrical values for various commercial, buildings and industrial applications. Energy measurements The meter provides fully bi-directional, 4-quadrant energy metering. The meter stores all accumulated active, reactive and apparent energy measurements in nonvolatile memory: � kWh, kVARh, kVAh (delivered) � kWh, kVARh, kVAh (received) � kWh, kVARh, kVAh net (delivered - received) � kWh, kVARh, kVAh absolute (delivered + received) All energy parameters represent the total for all three phases. NOTE: Based on the energy scale selection, when kWh, kVARh, kVAh (delivered) or kWh, kVARh, kVAh (received) of the energy parameters overflow at 999999999.999 all energy parameters value resets. Quadrant based VARh NOTE: Applicable only in EM6400NG+ RS-485 meter model. Quadrant based reactive energy values are available only on communication. These reactive energies are for Q1 , Q2, Q3 and Q4 quadrants. On communication quadrant based reactive energies will be recorded as follows: � Q1 (00 to 90 Degree) = Q1 VARh , Del � Q2 (90 to 180 Degree) = Q2 VARh , Del � Q3 (180 to 270 degree) = Q3 VARh, Rec � Q4 (270 to 360 degree) = Q4 VARh , Rec If energy is cleared, all quadrant based VARhs will be cleared. NHA2768503-05 43 Conzerv EM6400NG+ Measurements and calculations Min/max values When the readings reach their lowest or highest value, the meter updates and saves these min/max (minimum and maximum) quantities in non-volatile memory. The meter's real-time readings are updated once every 50 cycles for 50 Hz systems, or once every 60 cycles for 60 Hz systems. Power demand Power demand is a measure of average power consumption over a fixed time interval. NOTE: If not specified, references to demand are assumed to mean power demand. The meter measures instantaneous consumption and can calculate demand using various methods. Power demand calculation methods Power demand is calculated by dividing the energy accumulated during a specified period by the length of that period. How the meter performs this calculation depends on the method and time parameters you select (for example, timed rolling block demand with a 15-minute interval and 5-minute subinterval). To be compatible with electric utility billing practices, the meter provides the following types of power demand calculations: � Block interval demand � Synchronized demand � Thermal demand You can configure the power demand calculation method from the display or software. Block interval demand For block interval demand method types, you specify a period of time interval (or block) that the meter uses for the demand calculation. Select/configure how the meter handles that interval from one of these different methods: Type Timed Sliding Block Timed Block Timed Rolling Block Description Select an interval from 1 to 60 minutes (in 1-minute increments). If the interval is between 1 and 15 minutes, the demand calculation updates every 15 seconds. If the interval is between 16 and 60 minutes, the demand calculation updates every 60 seconds. The meter displays the demand value for the last completed interval. Select an interval from 1 to 60 minutes (in 1-minute increments). The meter calculates and updates the demand at the end of each interval. Select an interval and a subinterval. The subinterval must divide evenly into the interval (for example, three 5-minute subintervals for a 15-minute interval). Demand is updated at the end of each subinterval. The meter displays the demand value for the last completed interval. Block interval demand example The following illustration shows the different ways power demand is calculated using the block interval method. In this example, the interval is set to 15 minutes. 44 NHA2768503-05 Measurements and calculations Timed Sliding Block Calculation updates every 15 seconds 15-minute interval Conzerv EM6400NG+ Demand value is the average for the last completed interval 15 30 45 60 . . . Timed Block Calculation updates at the end of the interval Time (sec) Demand value is the average for the last completed interval 15-minute interval 15-minute interval 15-min 15 30 Timed Rolling Block Calculation updates at the end of the subinterval (5 minutes) 15-minute interval Time (min) 45 Demand value is the average for the last completed interval 1 5 20 25 30 35 40 45 Time (min) Synchronized demand You can configure the demand calculations to be synchronized using an external pulse input, a command sent over communications, or the device's internal realtime clock. Type Description Command synchronized demand Clock synchronized demand This method allows you to synchronize the demand intervals of multiple meters on a communications network. For example, if a programmable logic controller (PLC) input is monitoring a pulse at the end of a demand interval on a utility revenue meter, you can program the PLC to issue a command to multiple meters whenever the utility meter starts a new demand interval. Each time the command is issued, the demand readings of each meter are calculated for the same interval. This method allows you to synchronize the demand interval to the meter's internal real-time clock. This helps you synchronize the demand to a particular time, typically on the hour (for example, at 12:00 am). If you select another time of day when the demand intervals are to be synchronized, the time must be specified in minutes from midnight. For example, to synchronize at 8:00 am, select 480 minutes. NOTE: For these demand types, you can choose block or rolling block options. If you select a rolling block demand option, you need to specify a subinterval. Thermal demand Thermal demand calculates the demand based on a thermal response, which imitates the function of thermal demand meters. NHA2768503-05 45 Conzerv EM6400NG+ Measurements and calculations The demand calculation updates at the end of each interval. You can set the demand interval from 1 to 60 minutes (in 1-minute increments). Thermal demand example The following illustration shows the thermal demand calculation. In this example, the interval is set to 15 minutes. The interval is a window of time that moves across the timeline. The calculation updates at the end of each interval. 99% 90% Last completed demand interval % of Load 15-minute interval next 15-minute interval Time (minutes) Current demand The meter calculates current demand using the block interval, synchronized or thermal demand methods. You can set the demand interval from 1 to 60 minutes in 1 minute increments (for example, 15 minutes). Predicted demand The meter calculates predicted demand for the end of the present interval for kW, kVAR, and kVA demand, taking into account the energy consumption so far within the present (partial) interval and the present rate of consumption. Predicated demand is updated according to the update rate of your meter. The following illustration shows how a change in load can affect predicted demand for the interval. In this example, the interval is set to 15 minutes. 1:00 1:06 1:15 A Beginning of interval E Change in load B Demand for last completed interval F Predicted demand if load is added during interval; predicted demand increases to reflect increased demand C 15-minute interval G Predicted demand if no load is added D Partial interval H Time 46 NHA2768503-05 Measurements and calculations Conzerv EM6400NG+ Peak demand The meter records the peak (or maximum) values for kWD, kVARD, and kVAD power (or peak demand). The peak for each value is the highest average reading since the meter was last reset. These values are maintained in the meter's non-volatile memory. The meter also stores the date and time when the peak demand occurred. Timer The meter supports an active load timer, meter operation timer, and load run hours Active load timer Active load timer shows how much time a load has been running, based on the specified minimum current for the load timer setpoint setting. The active load timer data can be read through communication only. Meter operation timer Meter operating timer shows how long the meter has been powered up. Load run hours Load run hours show how much time a load has been running, based on accumulated energy - received and delivered. Load run hour counter is available under diag page. Run hours are displayed with 6 digits for Hours and 2 digits for Minutes. These run hour counters shall reset along with energy values. NHA2768503-05 47 Conzerv EM6400NG+ Power quality Power quality Harmonics overview This section describes the meter's power quality features and how to access power quality data. The meter measures voltage and current harmonics up to the 15th harmonic, and calculates Total Harmonic Distortion (THD%). Harmonics are integer multiples of the fundamental frequency of the power system. Harmonics information is required for compliance to system power quality standards such as EN50160 and meter power quality standards such as IEC 61000-4-30. The meter measures fundamental and higher harmonics relative to the fundamental frequency. The meter's power system setting defines which phases are present and determines how line-to-line or line-to-neutral voltage harmonics and current harmonics are calculated. Harmonics are used to identify whether the supplied system power meets required power quality standards, or if non-linear loads are affecting your power system. Power system harmonics can cause current flow on the neutral conductor, and damage to equipment such as increased heating in electric motors. Power conditioners or harmonic filters can be used to minimize unwanted harmonics. Total harmonic distortion % Total harmonic distortion (THD%) is a measure of the total per-phase voltage or current harmonic distortion present in the power system. THD% provides a general indication of the quality of a waveform. THD% is calculated for each phase of both voltage and current. Harmonic content calculations Harmonic content (HC) is equal to the RMS value of all the non-fundamental harmonic components in one phase of the power system. The meter uses the following equation to calculate HC: HC = (H2)2 + (H3)2 + (H4)2 ... THD% calculations THD% is a quick measure of the total distortion present in a waveform and is the ratio of harmonic content (HC) to the fundamental harmonic (H1). By default, the meter uses the following equation to calculate THD%: H THD = -----C--- x 100% H 1 Displaying harmonics data The meter displays voltage and current THD% data on the front panel, while the phase wise THD% data can be read through communication. 1.

Your meter typically does not require re-calibration. However, in some installations a final accuracy verification of the meters is required, especially if the meters will be used for revenue or billing applications. Accuracy test requirements The most common method for testing meter accuracy is to apply test voltages and currents from a stable power source and compare the meter's readings with readings from a reference device or energy standard. Signal and power source The meter maintains its accuracy during voltage and current signal source variations but its energy pulsing output needs a stable test signal to help produce accurate test pulses. The meter's energy pulsing mechanism needs approximately 10 seconds to stabilize after every source adjustment. The meter must be connected to control power in order to conduct accuracy verification testing. Refer to your meter's installation documentation for power supply specifications. DANGER HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH Verify the device's power source meets the specifications for your device's power supply. Failure to follow these instructions will result in death or serious injury. Control equipment Environment Control equipment is required for counting and timing the pulse outputs from an energy pulsing LED. � Most standard test benches have an arm equipped with optical sensors to detect LED pulses (the photodiode circuitry converts detected light into a voltage signal). � The reference device or energy standard typically has digital inputs that can detect and count pulses coming from an external source (i.e., the meter's pulse output). NOTE: The optical sensors on the test bench can be disrupted by strong sources of ambient light (such as camera flashes, florescent tubes, sunlight reflections, floodlights, etc.). This can cause test errors. Use a hood, if necessary, to block out ambient light. The meter should be tested at the same temperature as the testing equipment. The ideal temperature is about 23 �C (73 �F). Make sure the meter is warmed up sufficiently before testing. NHA2768503-05 53 Conzerv EM6400NG+ Verifying accuracy A warm-up time of 30 minutes is recommended before beginning energy accuracy verification testing. At the factory, the meters are warmed up to their typical operating temperature before calibration to help ensure that the meters will reach their optimal accuracy at operating temperature. Most high precision electronic equipment requires a warm up time before it reaches its specified performance levels. Energy meter standards allow the manufacturers to specify meter accuracy derating due to ambient temperature changes and self-heating. Your meter complies with and meets the requirements of these energy metering standards. For a list of accuracy standards that your meter complies to, contact your local Schneider Electric representative or download the meter brochure from www.se.com. Reference device or energy standard To help ensure the accuracy of the test, it is recommended that you use a reference device or reference energy standard with a specified accuracy that is 6 to 10 times more accurate than the meter under test. Before you start testing, the reference device or energy standard should be warmed up as recommended by its manufacturer. NOTE: Verify the accuracy and precision of all measurement equipment used in accuracy testing (for example, voltmeters, ammeters, power factor meters). Verifying accuracy test The following tests are guidelines for accuracy testing your meter; your meter shop may have specific testing methods. DANGER HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH � Apply appropriate Personal Protective Equipment (PPE) and follow safe electrical work practices. See NFPA 70E, CSA Z462 or other local standards. � Turn off all power supplying this device and the equipment in which it is installed before working on or in the equipment. � Always use a properly rated voltage sensing device to confirm that all power is off. � Do not exceed the maximum ratings of this device. � Verify the device's power source meets the specifications for your device's power supply. Failure to follow these instructions will result in death or serious injury. 1. Turn off all power supplying this device and the equipment in which it is installed before working on the device or equipment. 2. Use a properly rated voltage sensing device to confirm that all power is off. 54 NHA2768503-05 Verifying accuracy Conzerv EM6400NG+ 3. Connect the test voltage and current source to the reference device or energy standard. Ensure all voltage inputs to the meter under test are connected in parallel and all current inputs are connected in series.

Connect the control equipment used for counting the standard output pulses using one of these methods: Option Energy pulsing LED Pulse output Description Align the red light sensor on the standard test bench armature over the energy pulsing LED. Connect the meter's pulse output to the standard test bench pulse counting connections. NOTE: When selecting which method to use, be aware that energy pulsing LEDs and pulse outputs have different pulse rate limits. 5. Before performing the verification test, let the test equipment power up the meter and apply voltage for at least 30 seconds. This helps stabilize the internal circuitry of the meter. 6. Configure the meter's parameters for verifying accuracy testing. 7. Depending on the method selected for counting the energy pulses, configure the meter's energy pulsing LED or one of the pulse outputs to perform energy pulsing. Set the meter's energy pulse constant so it is in sync with the reference test equipment. 8. Perform accuracy verification on the test points. Run each test point for at least 30 seconds to allow the test bench equipment to read an adequate number of pulses. Allow 10 seconds of dwell time between test points. Required pulses calculation for accuracy verification testing Accuracy verification test equipment typically requires you to specify the number of pulses for a specific test duration. The reference test equipment typically requires you to specify the number of pulses required for a test duration of "t" seconds. Normally, the number of pulses required is at least 25 pulses, and the test duration is greater than 30 seconds. Use the following formula to calculate the required number of pulses: Number of pulses = Ptot x K x t/3600 Where: NHA2768503-05 55 Conzerv EM6400NG+ Verifying accuracy � Ptot = total instantaneous power in kilowatts (kW) � K = the meter's pulse constant setting, in pulses per kWh � t = test duration, in seconds (typically greater than 30 seconds) Total power calculation for accuracy verification testing Accuracy verification testing supplies the same test signal (total power) to both the energy reference/standard and the meter under test. Total power is calculated as follows, where: � Ptot = total instantaneous power in kilowatts (kW) � VLN = test point line-to-neutral voltage in volts (V) � I = test point current in amps (A) � PF = power factor The result of the calculation is rounded up to the nearest integer. For a balanced 3�phase Wye system: Ptot = 3 x VLN x I x PF x 1 kW/1000 W NOTE: A balanced 3�phase system assumes that the voltage, current and power factor values are the same for all phases. For a single-phase system: Ptot = VLN x I x PF x 1 kW/1000W Percentage error calculation for accuracy verification testing Accuracy verification testing requires you to calculate the percentage error between the meter being tested and the reference/standard. Calculate the percentage error for every test point using the following formula: Energy error = (EM - ES) / ES x 100% Where: � EM = energy measured by the meter under test � ES = energy measured by the reference device or energy standard. NOTE: If accuracy verification reveals inaccuracies in your meter, they may be caused by typical sources of test errors. If there are no sources of test errors present, please contact your local Schneider Electric representative. Accuracy verification test points The meter should be tested at full and light loads and at lagging (inductive) power factors to help ensure testing over the entire range of the meter. The test amperage and voltage input rating are labeled on the meter. Refer to the installation sheet or data sheet for your meter's nominal current, voltage and frequency specifications. 56 NHA2768503-05 Verifying accuracy Conzerv EM6400NG+ Watt-hour test point Sample accuracy verification test point Full load 100% to 200% of the nominal current, 100% of the nominal voltage and nominal frequency at unity power factor or one (1). Light load 10% of the nominal current, 100% of the nominal voltage and nominal frequency at unity power factor or one (1). Inductive load (lagging 100% of the nominal current, 100% of the nominal voltage and nominal power factor) frequency at 0.50 lagging power factor (current lagging voltage by 60� phase angle). VAR-hour test point Sample accuracy verification test point Full load 100% to 200% of the nominal current, 100% of the nominal voltage and nominal frequency at zero power factor (current lagging voltage by 90� phase angle). Light load 10% of the nominal current, 100% of the nominal voltage and nominal frequency at zero power factor (current lagging voltage by 90� phase angle). Inductive load (lagging 100% of the nominal current, 100% of the nominal voltage and nominal power factor) frequency at 0.87 lagging power factor (current lagging voltage by 30� phase angle). Energy pulsing considerations The meter's energy pulsing LED and pulse outputs are capable of energy pulsing within specific limits. Description Maximum pulse frequency Minimum pulse constant Maximum pulse constant Energy pulsing LED 35 Hz 1 pulse per k_h 9,999,000 pulses per k_h Pulse output 20 Hz The pulse rate depends on the voltage, current and PF of the input signal source, the number of phases, and the VT and CT ratios. If Ptot is the instantaneous power (in kW) and K is the pulse constant (in pulses per kWh), then the pulse period is: Pulse period (in seconds) = 3600 = 1 K x Ptot Pulse frequency (Hz) VT and CT considerations Total power (Ptot) is derived from the values of the voltage and current inputs at the secondary side, and takes into account the VT and CT ratios. The test points are always taken at the secondary side, regardless of whether VTs or CTs are used. If VTs and CTs are used, you must include their primary and secondary ratings in the equation. For example, in a balanced 3-phase Wye system with VTs and CTs: Ptot = 3 x VLN x VTp VTs x I x CTp x PF x 1 kW CTs 1000 W where Ptot = total power, VTp = VT primary, VTs = VT secondary, CTp = CT primary, CTs = CT secondary and PF = power factor. NHA2768503-05 57 Conzerv EM6400NG+ Verifying accuracy Example calculations This example calculation shows how to calculate power, pulse constants and maximum pulse frequency, and how to determine a pulse constant that reduces the maximum pulse frequency. A balanced 3-phase Wye system uses 480:120 volt VTs and 120:5 amp CTs. The signals at the secondary side are 119 volts line-to-neutral and 5.31 amps, with a power factor of 0.85. The desired pulse output frequency is 20 Hz (20 pulses per second). 1. Calculate the typical total output power (Ptot): Ptot = 3 x 119 x 480 x 5.31 x 120 x 0.85 x 1 kW = 154.71 kW 120 5 1000 W 2. Calculate the pulse constant (K): 3600 x (pulse frequency) K = = 3600 seconds/hour x 20 pulses/second Ptot 154.71 kW K = 465.5 pulses / kWh 3. At full load (120% of nominal current = 6 A) and power factor (PF = 1), calculate the maximum total output power (Pmax): Pmax = 3 x 119 x 480 120 x 6 x 100 x 1 x 1 kW = 205.6 kW 5 1000 W 4. Calculate the maximum output pulse frequency at Pmax: Maximum pulse frequency = K x Pmax = 465.5 pulses / kWh x 205.6 kW 3600 3600 seconds/hour Maximum pulse frequency = 26.6 pulses/second = 26.6 Hz 5. Check the maximum pulse frequency against the limits for the LED and pulse outputs: � 26.6 Hz LED maximum pulse frequency (35 Hz) � 26.6 Hz > pulse output maximum pulse frequency (20 Hz) NOTE: The maximum pulse frequency is within the limits for LED energy pulsing. However, the maximum pulse frequency is greater than the limits for pulse output energy pulsing. Pulse output frequencies greater than 20 Hz will saturate the pulse output and cause it to stop pulsing. Therefore in this example, you can only use the LED for energy pulsing. Adjustments to allow energy pulsing at the pulse outputs If you want to use the pulse output, you must reduce the output pulse frequency so it is within the limits. Using the values from the above example, the maximum pulse constant for the pulse output is: Kmax = 3600 x (pulse output maximum pulse frequency) = 3600 x 20 Pmax 205.6 Kmax = 350.14 pulses per kWh 1. Set the pulse constant (K) to a value below Kmax, for example, 300 pulses/ kWh. Calculate the new maximum output pulse frequency at Pmax: New maximum pulse frequency = K x Pmax = 300 pulses/kWh x 205.6 kW 3600 3600 seconds/hour New maximum pulse frequency = 17.1 pulses/second = 17.1 Hz 58 NHA2768503-05 Verifying accuracy Conzerv EM6400NG+ 2. Check the new maximum pulse frequency against the limits for the LED and pulse outputs: � 17.1 Hz LED maximum pulse frequency (35 Hz) � 17.1 Hz pulse output maximum frequency (20 Hz) As expected, changing K to a value below Kmax allows you to use the pulse output for energy pulsing. 3. Set the new pulse constant (K) on your meter. Typical sources of test errors If you see excessive errors during accuracy testing, examine your test setup and test procedures to eliminate typical sources of measurement errors. Typical sources of accuracy verification testing errors include: � Loose connections of voltage or current circuits, often caused by worn-out contacts or terminals. Inspect terminals of test equipment, cables, test harness and the meter under test. � Meter ambient temperature is significantly different than 23 �C (73 �F). � Floating (ungrounded) neutral voltage terminal in any configuration with unbalanced phase voltages. � Inadequate meter control power, resulting in the meter resetting during the test procedure. � Ambient light interference or sensitivity issues with the optical sensor. � Unstable power source causing energy pulsing fluctuations. � Incorrect test setup: not all phases connected to the reference device or the energy standard. All phases connected to the meter under test should also be connected to the reference meter/standard. � Moisture (condensing humidity), debris or pollution present in the meter under test. NHA2768503-05 59 Conzerv EM6400NG+ Power and power factor Power and power factor Power and power factor The sampled measurements taken at the meter's voltage and current inputs provide data for calculating power and power factor. In a balanced 3-phase alternating current (AC) power system source, the AC voltage waveforms on the current-carrying conductors are equal but offset by onethird of a period (a phase angle shift of 120 degrees between the three voltage waveforms). Current phase shift from voltage Electrical current can lag, lead, or be in phase with the AC voltage waveform, and is typically associated with the type of load -- inductive, capacitive or resistive. For purely resistive loads, the current waveform is in phase with the voltage waveform. For capacitive loads, current leads voltage. For inductive loads, current lags voltage. The following diagrams show how voltage and current waveforms shift based on load type under ideal (laboratory) conditions. Current and voltage in phase (resistive) Current leads voltage (capacitive) Current lags voltage (inductive) Real, reactive and apparent power (PQS) A typical AC electrical system load has both resistive and reactive (inductive or capacitive) components. Real power, also known as active power (P) is consumed by resistive loads. Reactive power (Q) is either consumed by inductive loads or generated by capacitive loads. Apparent power (S) is the capacity of your measured power system to provide real and reactive power. The units for power are watts (W or kW) for real power P, vars (VAR or kVAR) for reactive power Q, and volt-amps (VA or kVA) for apparent power S. 60 NHA2768503-05 Power and power factor Power flow Conzerv EM6400NG+ Quadrant 2 PF leading Power factor sign convention: IEEE = + IEC = - +Q (+kVAR, +kVARh) 90� Quadrant 1 PF lagging Power factor sign convention: IEEE = - IEC = + Reactive power (VAR) Imported/delivered Reactive power (VAR) Imported/delivered Apparent power (VA) Apparent power (VA) -P (-kW, -kWh) 180� Active power (W) Exported/received Active power (W) Exported/received Reactive power (VAR) Exported/received Apparent power (VA) Quadrant 3 PF lagging Power factor sign convention: IEEE = - IEC = - Active power (W) Imported/delivered Active power (W) Imported/delivered +P 0� (+kW, +kWh) Reactive power (VAR) Exported/received Apparent power (VA) Quadrant 4 PF leading Power factor sign convention: IEEE = + 270� IEC = + -Q (-kVAR, -kVARh) Positive real power P(+) flows from the power source to the load. Negative real power P(-) flows from the load to the power source. Power factor (PF) Power factor (PF) is the ratio of real power (P) to apparent power (S). PF is provided as a number between -1 and 1 or as a percentage from -100% to 100%, where the sign is determined by the convention. PF = --P S A purely resistive load has no reactive components, so its power factor is 1 (PF = 1, or unity power factor). Inductive or capacitive loads introduce a reactive power (Q) component to the circuit which causes the PF to become closer to zero. True PF and displacement PF The meter supports true power factor and displacement power factor values: � True power factor includes harmonic content. � Displacement power factor only considers the fundamental frequency. NOTE: Unless specified, the power factor displayed by the meter is true power factor. Power factor sign convention Power factor sign (PF sign) can be positive or negative, and is defined by the conventions used by the IEEE or IEC standards. You can set the power factor sign (PF sign) convention that is used on the display to either IEC or IEEE. NHA2768503-05 61 Conzerv EM6400NG+ Power and power factor PF sign convention: IEC PF sign correlates with the direction of real power (kW) flow. � Quadrant 1 and 4: Positive real power (+kW), the PF sign is positive (+). � Quadrant 2 and 3: Negative real power (-kW), the PF sign is negative (-). PF sign convention: IEEE PF sign is correlates with the PF lead/lag convention, in other words, the effective load type (inductive or capacitive): � For a capacitive load (PF leading, quadrant 2 and 4), the PF sign is positive (+). � For an inductive load (PF lagging, quadrant 1 and 3), the PF sign is negative (-). PF value display First digit of PF value indicates the Lag and Lead. Lag is indicated by "i" and Lead is indicated by "c" for first digit of PF value. NOTE: "i" = Inductive load/Lag PF and "c" = capacitive load/Lead PF. NOTE: Without the load, the PF value is displayed as "- - - -" Sample screen Power factor min/max convention The meter uses a specific convention for determining the power factor minimum and maximum values. � For negative PF readings, the minimum PF value is the measurement closest to -0 for PF readings between -0 to -1. For positive PF readings, the minimum PF value is the measurement closest to +1 for PF readings between +1 to +0. 62 NHA2768503-05 Power and power factor Conzerv EM6400NG+ � For negative PF readings, the maximum PF value is the measurement closest to -1 for PF readings between -0 to -1.
