Measuring the Neutral Current
4-pole circuit breakers or 3-pole circuit breakers with the ENCT wired and configured measure the neutral
current:
For a 3-pole circuit breaker, the neutral current is measured by adding a current transformer on the
neutral conductor for the transformer information. Refer to the
Masterpact Catalog
For a 4-pole circuit breaker, the neutral current is measured systematically
The neutral current is measured in the same way as the phase currents.
Measuring the Ground-Fault Current
The ground-fault current is calculated or measured in the same way as the phase currents, according to
the circuit breaker configuration, as shown in the following table.

Measuring the Earth-Leakage Current (Micrologic 7.0 X)
The earth-leakage current is measured by a rectangular sensor encompassing the three phases or the
three phases and neutral.
Measuring the Phase-to-Neutral Voltages
4-pole circuit breakers or 3-pole circuit breakers with the ENVT wired and configured measure the phase-
to-neutral (or line-to-neutral) voltages V1N, V2N, and V3N:
For a 3-pole circuit breaker, it is necessary to:
Connect the wire from the ENVT to the neutral conductor
Declare the ENVT in the system type setting
For 4-pole circuit breakers, the phase-to-neutral voltages are measured systematically
The phase-to-neutral voltages are measured in the same way as the phase-to-phase voltages.
Calculating the Average Current and Average Voltage
Micrologic X control units calculate the:
Average current Iavg, the arithmetic mean of the 3-phase currents:
Iavg = (I1 + I2 + I3)/3
Average voltages:
Phase-to-phase Vavg, the arithmetic mean of the 3 phase-to-phase voltages:
Vavg = (V12 + V23 + V31)/3
Phase-to-neutral Vavg, the arithmetic mean of the 3 phase-to-neutral voltages (4-pole circuit
breakers or 3-pole circuit breakers wired and configured with the ENVT):
Vavg = (V1N + V2N + V3N)/3
Measuring the Current and Voltage Phase Unbalances
Micrologic X control units calculate the current unbalance for each phase (3 values).
The current unbalance is a percentage of the average current:
Micrologic X control units calculate:
The phase-to-phase voltage unbalance for each phase (3 values)

Power Metering
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 maximum and minimum values for each of these powers
The cos ϕ and power factor (PF) indicators
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:

The following table lists the metering options:
3-Pole Circuit Breaker, Distributed Neutral
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):
NOTE: The power values are:
Signed when read using the communication network.
Not signed when displayed on the Micrologic X display screen.
When there is voltage metering on the neutral (4-pole or 3-
pole 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 (3-
pole 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)

neutral conductor is zero:

Power Sign Convention
The sign for the power running through the circuit breaker depends on the type of connection:
Circuit breakers with the active power flowing from upstream (top) to downstream (bottom) should be
set with the power sign P+
Circuit breakers with the active power flowing from downstream (bottom) to upstream (top) should be
set with the power sign P-

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
(seepage23)
.
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:

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:
1 Irms: rms value of the harmonic waveform
2 I1: fundamental current
3 I3: third order harmonic current
4 I5: fifth order harmonic current

Total harmonic distortions related to the fundamental value (THD(V), THD(I)) are displayed on the
Micrologic X display screen.
In addition, total harmonic distortions related to rms values (THD-R(V), and THD-R(I)) can be displayed
with Ecoreach software
Displaying the Total Harmonic Distortion
The total harmonic distortion THD can be displayed in the following ways:
On the Micrologic X display screen:
THD(I) at Home → Measures → I Harmonics
THD(V) at Home → Measures → V Harmonics

Through the communication network
Current THD
The current THD is a percentage of the rms value of harmonic currents of ranks greater than 1 in relation
to the rms value of the fundamental current (first order). The control unit calculates the total harmonic
current distortion THD up to the fifteenth harmonic:
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.
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.
Voltage THD
The voltage THD is the percentage the rms value of harmonic voltages greater than 1 in relation to the rms
value of the fundamental voltage (first order). The control unit calculates the voltage THD up to the fifteenth
harmonic:
This factor can in theory be higher than 100% but is in practice rarely higher than 15%.
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.

Power Factor PF and cos ϕ Measurement
Power Factor PF
The control unit calculates:
The power factor per phase PF1, PF2, PF3, from the phase active and apparent powers
The total power factor PF from the total active power Ptot and the total apparent power Stot
NOTE: Stot is the vector or arithmetic total apparent power, depending on the setting
(see page 120)
.
This indicator qualifies:
The oversizing necessary for the installation power supply when harmonic currents are present
The presence of harmonic currents by comparison with the value of the cos ϕ (see below)
cos ϕ
The control unit calculates:
The cos ϕ per phase from the phase active and apparent powers of the fundamental
the cos ϕ from the total active power Pfundtot and the total apparent power Sfundtot of the fundamental
(first order)
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:
The graph below specifies the value of PF/cos ϕ as a function of the THD(I):
By comparing the 2 values, it is possible to estimate the level of harmonic deformation on the supply.
Sign for the Power Factor PF and cos ϕ
2 sign conventions can be applied for these indicators:
IEC convention: The sign for these indicators complies strictly with the signed calculations of the powers
(that is, Ptot, Stot, Pfundtot, and Sfundtot).
IEEE convention: The indicators are calculated in accordance with the IEC convention but multiplied by
the inverse of the sign for the reactive power (Q).

The figures below define the sign for the power factor PF and cos ϕ by quadrant (Q1, Q2, Q3 and Q4) for
both conventions:
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.

Event Management
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:
For information about IFE events, refer to the
IFE Ethernet Interface for LV Circuit Breaker - User Guide

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.
