Presentation
The control unit calculates the electrical quantities required for power management:
 The real-time values of the:
 Active powers (total Ptot and per phase) in kW
 Reactive powers (total Qtot and per phase) in kVAR
 Apparent powers (total Stot and per phase) in kVA

The operating quadrant and type of load (leading or lagging)
All these electrical quantities are continuously calculated and their value is updated once a second at rated
frequency.
Principle of Power Metering
The control unit calculates the power values from the current and voltage samples.
The calculation principle is based on:
 Definition of the powers
 Algorithms depending on the type of circuit breaker (4-pole or 3-pole)
 Set value of the power sign (circuit breaker powered from the top or underside)
The calculation algorithm is explained in the specific topic (see page 120).
Calculations use harmonics up to the fifteenth.
Total Power Calculation Method
The total reactive and apparent power can be calculated by one of the two following methods:
 Vector
 Arithmetic
NOTE: The total active power is calculated as a sum of the phase powers: Ptot = P1 + P2 + P3
The calculation method can be set in the following ways:
 On the Micrologic X display screen, at Home → Configuration → Measures → Total P Calcul

4-pole or 3-pole with ENVT: 3-wattmeter method
3-pole without ENVT: 2-wattmeter method
When there is voltage metering on the neutral (4-pole or 3pole circuit breaker with ENVT wired and configured), the
control unit measures the power by using 3 single-phase
loads downstream.
When there is no voltage metering on the neutral (3pole circuit breaker), the control unit measures the
power:
 Using the current from 2 phases (I1 and I3) and
composite voltages from each of these 2 phases in
relation to the third (V12 and V23)
 using the fact that by definition the current in the
neutral conductor is zero:
I1 + I2 + I3 = 0
The following table lists the metering options:

Declare the ENVT in the system type setting (see page 114).
NOTE: Declaration of the ENVT alone does not result in correct calculation of the powers. It is essential to
connect the wire from the ENVT to the neutral conductor.
Power Sign and Operating Quadrant
By definition, the active powers are:
 Signed + when they are consumed by the user, that is, when the device is acting as a receiver.
 Signed - when they are supplied by the user, that is, when the device is acting as a generator.
By definition, the reactive powers have:
The same sign as the active energies and powers when the current lags behind the voltage, that is,
when the device is inductive (lagging).
 The opposite sign to the active energies and powers when the current is ahead of the voltage, that is,
when the device is capacitive (leading).

These definitions therefore determine 4 operating quadrants (Q1, Q2, Q3, and Q4):

Energy Metering
Presentation
The control unit calculates the different types of energy using energy meters and provides the values of:
 The total active energy Ep, the active energy supplied EpOut, and the active energy consumed EpIn
 The total reactive energy Eq, the reactive energy supplied EqOut, and the reactive energy consumed
EqIn
 The total apparent energy Es
The energy values are calculated, and shown as an hourly consumption. Values update once a second at
rated frequency. Values are stored in non-volatile memory once an hour.
NOTE: To ensure reliable energy measurement across the current range the control unit must be powered
with an external 24 Vdc power supply or VPS module (see page 23).
NOTE: The energies per phase are available as an option (see page 129). They are calculated using the
same principles as total energies.
Principle of Energy Calculation
By definition energy is the integration of the real-time power over a period T. The integration period T is
equal to a number of cycles equal to the rated frequency.
Partial Energy Meters
For each type of energy, active or reactive, a partial consumed energy meter and a partial supplied energy
meter calculate the accumulated energy by incrementing once a second:
 The contribution of the consumed power to the consumed energy meter
Ein(t)(consumed) = Ein(t - 1) + (Gin(t))/3600 where Gin = Ptot or Qtot consumed
 The contribution as an absolute value of the supplied power for the supplied energy meter (supplied
power is always counted negatively)
Eout(t)(supplied) = Eout(t - 1) + (|Gout(t)|)/3600 where Gin = Ptot or Qtot supplied
For each partial energy meter two types of counter are available: one which can be reset and one which
cannot be reset.
Energy Meters
From the partial energy meters and for each type of energy, active or reactive, an energy meter provides
either of the following measurements once a second:
 The absolute energy, by adding the consumed and supplied energies together. The energy
accumulation mode is absolute.
E(t)absolute = Ein(t) + Eout(t)
 The signed energy, by differentiating between consumed and supplied energies. The energy
accumulation mode is signed.
E(t)signed = Ein(t) - Eout(t)
The apparent energy Es is always counted positively.
Selecting Energy Calculation
The information sought determines calculation selection:
 The absolute value of the energy that has crossed the poles of a circuit breaker or the cables of an item
of electrical equipment is relevant for maintenance of an installation.
 The signed values of the energy supplied and the energy consumed are required to calculate the
economic cost of an item of equipment.
By default, absolute energy accumulation mode is configured.
Select the energy calculation mode using any of the following methods:
 On the Micrologic X display screen, on the screens Home → Configuration → Measures → E calcul

Harmonic Currents and Voltages
Origin and Effects of Harmonics
Many nonlinear loads present on an electrical network create harmonic currents in the electrical network.
These harmonic currents:
 Distort the current and voltage waves.
 Degrade the quality of the distributed energy.
These distortions, if they are significant, can result in:
 Malfunctions or degraded operation in the powered devices.
 Unwanted heat rise in the devices and conductors.
 Excessive power consumption.
These various problems increase the system installation and operating costs. It is therefore necessary to
control the energy quality carefully.
Definition of a Harmonic
A periodic signal is a superimposition of:
 The original sinusoidal signal at the fundamental frequency (for example, 50 Hz or 60 Hz)
 Sinusoidal signals whose frequencies are multiples of the fundamental frequency called harmonics
 Any DC component
This periodic signal is broken down into a sum of terms:
where:
 y0: value of the DC component
 yn: rms value of the nth harmonic
 ω: pulsation of the fundamental frequency
 ϕn: phase displacement of harmonic component n
NOTE: The first harmonic is called the fundamental.
Example of a current wave distorted by a harmonic component:
Irms
H1 (50 Hz)
H3 (150 Hz)
H5 (250 Hz)

The current THD is a percentage of the rms value of harmonic currents of ranks greater than 1 in relation

The current THD can be higher than 100%.
Use the total harmonic distortion THD(I) to assess the distortion of the current wave with a single number.
The table below shows the THD limit values.
THD(I) Value
Comments
THD(I) < 10%
Low harmonic currents: little risk of malfunctions.
10% < THD(I) < 50%
Significant harmonic currents: risk of heat rise, oversizing of supplies.
50% < THD(I)
High harmonic currents: the risks of malfunction, degradation, and dangerous heat rise
are almost certain unless the installation is calculated and sized with this restriction in
mind.
Distortion of the current wave created by a nonlinear device with a high THD(I) can lead to distortion of the
voltage wave, depending on the level of distortion and the source impedance. This distortion of the voltage
wave affects all of the devices powered by the supply. Sensitive devices on the system can therefore be
affected. A device with a high THD(I) may not be affected itself but could cause malfunctions on other,
more sensitive devices on the system.
NOTE: THD(I) metering is an effective way of determining the potential for problems from the devices on
electrical networks.

The current THD-R is a percentage of the rms value of harmonic currents of ranks greater than 1 in relation
to the total harmonic current. The control unit calculates the total harmonic current distortion THD-R up to
the fifteenth harmonic using the following equation:
The current THD-R cannot be higher than 100%.

NOTE: Stot is the vector or arithmetic total apparent power, depending on the setting (see page 120).

This indicator qualifies use of the energy supplied.
Power Factor PF and cos ϕ when Harmonic Currents are Present
If the supply voltage is not too distorted, the power factor PF is expressed as a function of the cos ϕ and
the THD(I) by:

NOTE: For a device, a part of an installation which is only a receiver (or generator), the advantage of the
IEEE convention is that it adds the type of reactive component to the PF and cos ϕ indicators:
 Lead: positive sign for the PF and cos ϕ indicators
 Lag: negative sign for the PF and cos ϕ indicators
Managing the Power Factor PF and cos ϕ: Minimum and Maximum Values
Managing the PF and cos ϕ indicators consists of:
 Defining critical situations
 Implementing monitoring of the indicators in accordance with the definition of critical situations
Situations are considered critical when the values of the indicators are around 0. The minimum and
maximum values of the indicators are defined for these situations.
The figure below illustrates the variations of the cos ϕ indicator (with the definition of the cos ϕ MIN/MAX)
and its value according to IEEE convention for a receiver application:

PF MAX (or cos ϕ MAX) is obtained for the smallest positive value of the PF (or cos ϕ) indicator.
PF MIN (or cos ϕ MIN) is obtained for the largest negative value of the PF (or cos ϕ) indicator.
NOTE: The minimum and maximum values of the PF and cos ϕ indicators are not physically significant:
they are markers which determine the ideal operating zone for the load.
Monitoring the cos ϕ and Power Factor PF Indicators
According to the IEEE convention, critical situations in receiver mode on a capacitive or inductive load are
detected and discriminated (2 values).
The table below indicates the direction in which the indicators vary and their value in receiver mode.

Monitoring the Contact State
Presentation
The pole contacts undergo wear due to the number of operating cycles with current and interrupted current
during short circuits. It is recommended to check them at periodic intervals to decide whether the contacts
must be changed or not. To avoid regular inspection of the contacts and the arc chute, the contact wear
estimate helps with the planning of visual inspections based on the estimated wear (from 0% - new contact
- to 100% - totally worn contact).
The contact wear increases every time the circuit breaker interrupts or establishes the circuit with current.
Function Outputs
The function displays the contact wear on Ecoreach and Masterpact MTZ mobile App:


Monitoring the Circuit Breaker Service Life
Presentation
Circuit breaker service life depends on the daily number of operating cycles with or without current. The
maximum service life depends on the number of operating cycles indicated in the catalog under
mechanical and electrical durability. The service life indicator helps anticipate the replacement of the
breaking block before mechanical or electrical breakdown.
Operating Principle
Each time the circuit breaker operates (performs an open and close cycle with or without current), the
corresponding mechanical or electrical operating counter is incremented. The Micrologic X control unit
calculates the number of cycles performed as a percentage of the maximum number of operations. The
percentage of lifetime remaining for the device is calculated.
Function Outputs
The circuit breaker service life is presented as one of the following:

OK if remaining life > 20%

Medium level alarm if remaining life < 20%

High-level alarm if remaining life = 0%

Definition
An event is a change in state of digital data, or any incident detected by the Micrologic X control unit, IFE
or EIFE Ethernet interface, or IO modules.
Events are time stamped and logged in the event history of each module.
Events are categorized according to a level of severity:
 High
 Medium
 Low
All high and medium-level events generate an alarm and a pop-up notification screen (see page 169) on
the Micrologic X control unit display screen.
Low-level events are information-type events. They can be consulted through Ecoreach software.
Alarms and trips are events that require specific attention from the user:
 A trip is an event generated when the circuit breaker trips.
 An alarm is an event with medium or high severity.
The information in this chapter is valid for events detected by the Micrologic X control unit. Refer to the
following documents for events detected by the IFE or EIFE Ethernet interface, or by IO modules:

Event Status Overview
Event Status Definition
The status of an event is active, inactive, or held. It depends on the event type and whether it is latched or
unlatched. The status of all events can be consulted at any time (see page 170).
Event Type
Events can be the following types:
 Occurrence/completion (on/off): Events which have a defined beginning and end, representing the
beginning or end of a system state. The occurrence and completion are both time-stamped and logged
in a history. For example, control unit overheating is an occurrence/completion event.
 Instantaneous: Events with no duration. For example, the reception of an opening order, a change to
settings, or a circuit breaker trip are instantaneous events.
The event type cannot be customized.
Latched or Unlatched Events
An event can be unlatched or latched:
 Unlatched: The event status is active while the cause of the event is present. It automatically returns to
inactive when the cause of the event disappears or is resolved.
 Latched: The event status does not automatically return to inactive when the cause of the event
disappears or is resolved. It stays in the held state until it is reset by the user.
The latched/unlatched mode for certain events (see page 173) can be customized on Ecoreach software.
Disabling Events
Certain events can be disabled so that the event is not taken into consideration by the Micrologic X control
unit. In this case the event is not logged in a history and does not generate an alarm.
Events can be disabled through Ecoreach software. For more information about which events can be
disabled, refer to the event list (see page 173). Events can be enabled again after being disabled.

Resetting Events
Events can be reset in the following ways:
 By pressing the Test/Reset button on the front of the Micrologic X control unit for 3–15 seconds.
 With Ecoreach software.
 With Masterpact MTZ mobile App.
 By sending a reset command using the communication network. This function is password protected.
Reset commands do not target specific events. All held event states managed by the Micrologic X control
unit are reset, and all trip cause LEDs are cleared.
Reset commands target a specific module. For example, pressing the Test/Reset button for 3–15 seconds
resets the events of the Micrologic X control unit but does not reset the events of the IO module.
The reset command generates an event and it is logged in the operation history.

 By a pop-up screen on the Micrologic X control unit (high and medium-level events).
 By SDE1 standard fault-trip indication contact and SDE2 optional fault-trip indication contact (Trip
events).
All events can be configured to be notified in the following ways:
 By optional M2C module.
 By optional IO module.
 By email from IFE or EIFE Ethernet interface.
Pop-up Screen
All high and medium-level events generate a pop-up screen on the Micrologic X display screen
(see page 57).
 A red pop-up screen indicates a trip or high-level event, needing immediate attention.
 An orange pop-up screen indicates a medium-level alarm, recommending action.
SDE Fault-Trip Indication Contacts
M2C Notifications
Ecoreach software allows the assignment of one or more events to each M2C output.
The M2C output remains on as long as one of the events assigned is active or held.
Ecoreach software also enables the status of the M2C outputs to be forced.
Forcing or unforcing a M2C output generates the following events:
 M2C output 1 unforced / forced change.
 M2C output 2 unforced / forced change.
IO Module Notifications
Ecoreach software allows the assignment of one or more events to IO module outputs available according
to the IO module predefined or user-defined applications selected. The IO module output remains on as
long as one of the events assigned is active or held. The operating mode of the IO module output must be
set as non-latching. Refer to the IO Input/Output Application Module for One Circuit Breaker - User Guide.
Email Notification
The occurrence of an event is notified by email, if configured to do so.

Introduction
The event status table contains the status of all events at the time of consultation. The status can be
inactive, active or held.
Event status for active and held events is displayed:
 On the Micrologic X display screen.
 With Ecoreach software.
 With the Masterpact MTZ mobile App.
The status of an event can be checked using the communication network.
Displaying the Event Status Table on the Micrologic X Display Screen
Display the event status table on the Micrologic X display screen at Home → Alarms/History → Alarms.
High and medium-level active and held events are displayed.
The events are displayed in no specific order, with the description of the event and the time it occurred.
If the event is completed while the screen is open, the message Completed is displayed on the screen.

Event History
Overview
All events are logged in one of the histories of the Micrologic X control unit:
 Trip
 Protection
 Diagnostic
 Metering
 Configuration
 Operation
 Communication
All severities of events are logged, including low-level events.
The occurrence and completion of an event are logged as two separate events.
Events logged in histories are displayed as follows:
 On the Micrologic X display screen
 With Ecoreach software
 With Masterpact MTZ mobile App
The event histories can be downloaded using the communication network.
The following information is logged in a history for each event:
 Event ID: name or code or user message
 Event type: occurrence/completion or pulse
 Time stamp: date and time of occurrence/completion
 Context data (only for certain events)
Number of Events in Each History
Each history has a predefined maximum size. When a history is full, each new event overwrites the oldest
event in the relevant history.
