Demand Calculation Methods
Power demand is the energy accumulated during a specified period divided by the length of the period. Current demand is calculated using arithmetical integration of the current RMS values during a time period, divided by the length of the period. How the power meter performs this calculation depends on the selected method. To be compatible with electric utility billing practices, the power meter provides block interval power/current demand calculations.
For block interval demand calculations, you select a block of time (interval) that the power meter uses for the demand calculation and the mode the meter uses to handle the interval. 2 different modes are possible:
· Fixed block - Select an interval from 10, 15, 20, 30, 60 minutes. The power meter calculates and updates the demand at the end of each interval.
· Sliding block - Select an interval from 10, 15, 20, 30, 60 minutes. For demand intervals less than 15 minutes, the value is updated every 15 seconds. For demand intervals of 15 minutes and greater, the demand value is updated every 60 seconds. The power meter displays the demand value for the last completed interval.
The following figures illustrate the 2 ways to calculate demand power using the block method. For illustration purposes, the interval is set to 15 minutes.

DOCA0005EN-12

iEM3000 series user manual

Front panel display and meter setup

Peak Demand
In nonvolatile memory, the power meter maintains a maximum operating demand value called peak demand. The peak is the highest value (absolute value) for each of these readings since the last reset.
You can reset peak demand values from the power meter display. You should reset peak demand after changes to basic power meter setup such as CT ratio or power system configuration.

Resets

The following resets are available, depending on your meter model:

Reset Partial energy Input metering

Communications via Modbus

Modbus communication overview
Modbus RTU protocol is available on the iEM3150, iEM3155, iEM3250, iEM3255, iEM3350, iEM3355, iEM3455, and iEM3555.
The information in this section assumes that you have an advanced understanding of Modbus communications, your communications network and the power system that your meter is connected to.
There are three different ways of using Modbus communication: · By sending commands using the command interface (see "Command interface
overview" on page 49) · By reading the Modbus registers (see "Modbus register list" on page 56) · By reading Device Identification (see "Read Device Identification" on page 65)

Modbus communications settings
Before communicating with the device using Modbus protocol, use the display to configure the following settings:

Settings Baud rate
Parity Address

Possible values
9600 Baud 19 200 Baud 38 400 Baud Odd Even None NOTE: number of stop bits = 1 1247

Communications LED indicator for Modbus devices
The yellow communications LED indicates the status of communication between the meter and the master as follows:

If... The LED is flashing The LED is off

Then... Communication with the device has been established. NOTE: If there is an error online, the LED also flashes. There is no active communication between the master and the slave

Key terms

Term

Definition

APDU

Application protocol data unit, that data portion of a BACnet message.

Confirmed message COV

A message for which the device expects an answer.
Change of value, sets the amount by which a value has to change in order for the meter to send a subscription notification.

Device MS/TP

A BACnet device is a unit that is designed to understand and use BACnet protocol (for example, a BACnet-enabled meter or software program). It contains information about the device and device data in objects and object properties. Your meter is a BACnet device.
Master-slave/token-passing over RS-485.

Object Present value

Represents the device and device data. Each object has a type (for example, analog input or binary input) and has a number of properties.
The current value of an object.

Property Service

The smallest piece of information in BACnet communications, it consists of a name, data type and value.
Messages from one BACnet device to another.

Subscription Subscription notification

Creates a relationship between the server and the meter, so that when the present value property of an object changes by more than the configured COV threshold (COV_Increment), a notification is sent.
The message the meter sends to indicate a COV event has occurred.

Unconfirmed message A message for which the device does not expect an answer.

Power, energy and power factor

Chapter 11 Power, energy and power factor

NOTE: The descriptions in this section assume that you are an electrical energy consumer, not a supplier.

Power (PQS)

A typical AC electrical system load has both resistive and reactive (inductive or capacitive) components. Resistive loads consume real power (P) and reactive loads consume reactive power (Q).
Apparent power (S) is the vector sum of real power (P) and reactive power (Q):
S = P2 + Q2
Real power is measured in watts (W or kW), reactive power is measured in vars (VAR or kVAR) and apparent power is measured in volt-amps (VA or kVA).

Power and the PQ coordinate system
The meter uses the values of real power (P) and reactive power (Q) on the PQ coordinate system to calculate apparent power.

iEM3000 series user manual

Energy delivered (imported) / energy received (exported)
The meter interprets energy delivered (imported) or received (exported) according to the direction of real power (P) flow.
Energy delivered (imported) means positive real power flow (+P) and energy received (exported) means negative real power flow (-P).

Power factor (PF)
Power factor (PF) is the ratio of real power (P) to apparent power (S), and is a number between 0 and 1.

PF = P-S
An ideal, purely resistive load has no reactive components, so its power factor is one (PF = 1, or unity power factor). A purely inductive or capacitive load no resistive components, so its power factor is zero (PF = 0).

True PF

True power factor includes harmonic content.

PF lead / lag convention
The meter correlates leading power factor (PF lead) or lagging power factor (PF lag) with whether the current waveform is leading or lagging the voltage waveform.

Current phase shift from voltage
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.
