phase concordance
unit

principle

Phase concordance testing for
VPIS- V1 and VPIS- V2 must be
carried out each time a cable is
connected to a functional unit.

It is a way of making sure that all
three cables are each connected
to the corresponding phase of
the substation.

The principle of the phase
concordance unit is that it allows
a check of the phase concordance between 2 energised
functional input units on the
same substation.

note

In custom mode, the protection set
points may not be assigned to the
Mitop trip unit output.
In this case, the fault indication
LED may be active, without being
associated with the circuit breaker
trip.

Depending on the application, this

operation according to the
power supply mode
(VIP400)

The VIP400 is a stand- alone protection relay powered by its current sensors.
When current is present in the
medium- voltage (MV) network,
the protections and the display
work and it is possible to enter settings and view measurements.
The current in the MV network on
which the VIP operates is called
the ’pick - up current’.
When no current is flowing through
the circuit breaker (for example circuit breaker open), or when the
current in the MV network is too
low, the VIP is off and nothing
appears on its display.
If current appears, the protection
functions are activated and trip the
circuit breaker - or not - according to their settings.

The additional time taken by the
VIP to start when current appears
is called the ’pick - up time’.
More information on the value of
the pick - up current and the pick up time are available in the VIP
Function Characteristics
Please consult the reference
NRJED311207EN.

07897073EN01 revision : 11

operation according to the
power supply mode
(VIP410)

The VIP410 is a relay with a dual
power supply. It is powered both
autonomously by its sensors and
by the auxiliary power supply.
Like for the VIP400, the
self- powered supply allow the
protection functions to work even if
the auxiliary power supply fails.

The auxiliary power supply is used
to power functions that do not
depend on the current being
present in the MV network. These
functions are marked in the
function table (Please consult the
reference NRJED311207EN). The
auxiliary power supply must be
present in order them to work.

integral battery

The VIP has an integral battery. It
is used to:
H activate the user- machine
interface in order to enter settings
when the VIP is not supplied with
power
H illuminate the fault indication
LEDs when the VIP is no longer
supplied with power after giving
theopening order to the circuit

H power the internal calendar
When the VIP is not supplied with
power:
Pressing and holding down the
key will activate battery- powered
operation of the user- machine
interface. It is then possible to
access the menus in order to enter
settings.
In this case, the display
turns off automatically after 3
minutes of inactivity on the keypad.

The pocket battery module is an
accessory that can be connected
to the front panel of VIP relays. It
contains a battery that can be
used to power the VIP in order to:
H enter settings if the integral battery is missing and if the VIP is not
powered by the current sensors
H test the VIP, please consult the
reference NRJED311207EN.

pocket battery module

The protection functions are
activated automatically if the current reappears.
The integral battery plays no part
in operating the protection functions. The protection functions
work even when there is no battery.

NOTE :
H in battery operation mode, the
VIP processor runs with a reduced
clock frequency to ensure the battery life is maintained. As a result,
the user- machine interface may
be slower to react.
during a setting operation with
the VIP powered by its internal
battery alone, the clock display is
not refreshed on screen. However
the internal clock increments normally.

frequency

The network frequency (50 Hz or
60 Hz) is a parameter that must be
known for operation of the VIP40
and VIP45 signal processing algorithms.
They therefore have an automatic
frequency recognition system.
The recognized value
(50 Hz or 60 Hz) is stored and the
VIP works permanently with this
value.
This stored value will be used each
time the VIP starts
For the VIP to recognize the network frequency and store it, it has
to detect a current on phase 1 for
a minimum period of 5 seconds in
the range 50 Hz +/- 2 Hz or 60
Hz +/- 2 Hz.
This detection happens when
the VIP starts.

earth current (ANSI
50N- 51N)

Earth current maximum protection
enables overcurrents due to
phase- to- earth faults to be
detected. It makes use of the measurement of the earth current’s
fundamental component.

2 independent thresholds (Io>
and Io>>)
H the lower threshold (Io>) can
be set to either a definite time (DT)
or an inverse time (IDMT) curve,
with the choice of standardised
curve (IEC, IEEE, RI) and the possibility of activating an inverse time
duration.
H the upper threshold (Io>>) has
only a definite time (DT) setting.
The minimum setting gives instantaneous operation (ANSI 50 function).

Depending on the level of sensitivity required, there are 2 types of
Sepam:

phase current maximum
protection (ANSI 50- 51)

Phase current maximum protection
enables overcurrents due to
phase- to- phase faults to be
detected. It makes use of the measurement of the fundamental component of the currents from the 3
phase CTs.

thermal overload protection
(ANSI 49RMS)

This protection enables cables and
HV/LV transformers to be protected against overloads based on
the measurement of absorbed current.
This protection uses a thermal
model based on current measurements to evaluate temperature
rise. The current used for this protection is a 3- phase RMS current
that takes into account up to 13th
order harmonics.

2 independent thresholds (I>
and I>>)
H the lower threshold (I>) can be
set to either a definite time (DT) or
an inverse time (IDMT) curve, with
the choice of standardised curve
(IEC, IEEE, RI) and the possibility
of activating an inverse time duration.
H the upper threshold (I>>) has
only a definite time (DT) setting.
The minimum setting gives instantaneous operation (ANSI 50 function).

This protection has 2 settings:
maximum allowable continuous
current, which corresponds to the
maximum thermal withstand of the
equipment to be protected (this
allowable continuous current corresponds to a temperature rise of
100%)
H heating/cooling time constant of
the equipment.

low sensitivity of phase and
earth current maximum
protection settings (Cold
Load Pick - Up)

The cold load pickup function
avoids nuisance tripping when the
equipment is powered- up, especially after a long break in operation. It allows the protection thresholds to be temporarily increased.

High currents at cold load pickup may be due to:
H simultaneous powering- up of
all the loads in an installation.
H power transformer magnetising
currents.
H motor starting currents.

Protection concerned

Operating means

Phase current maximum protection

After circuit breaker closing, the tripping thresholds (I> or I>>) are
increased or blocked for the set duration.

Earth current maximum protection

After circuit breaker closing, the tripping thresholds (Io> or Io>>) are
increased or blocked for the set duration.
Or
The protection is restrained by the detection of sensor saturation (measurement of 2nd order harmonic level).

logic discrimination
(ANSI 68)

This function achieves:
H tripping discrimination in the
event of a short - circuit between
phases, or from phase to earth, for
all network types
H reduced tripping time of the circuit breaker that is closest to the
source.

external tripping

The Sepam series 10A enables,
via a logic input, a tripping order
from an external protection means
to be taken into account.

earth current measurement

This measurement enables the
value of the fundamental component of the earth current to be displayed.

phase current measurements

These measurements enable the
RMS value of the phase currents to
be displayed; it takes into account
up to 13th order harmonics.

phase current maximum
readings

This function enables the largest
average current value of each of
the 3 phases to be displayed, as
well as giving the highest absorbed current during load peaks.

07897073EN01 revision : 11

All Sepam series 10B and 10A
are able to emit an await logic
order should a fault be detected
by the phase and earth current
maximum protection functions.
Only the Sepam series 10A is
able to receive an await logic
order that blocks its tripping
signal. A safety mechanism ensures the protection operates in the
event of a fault with the blocking
signal wiring.

This function displays the 3 phase
currents.

This function enables the characteristics of the last fault to be displayed. The Sepam indicates the
cause of the fault, the value of the
phase currents and the earth current when the fault occurred, and
the time and date of the fault.
This information is memorised until
the next fault occurs.

Cause of faults recorded: I>,
I>>, Io>, Io>> and thermal protection.

recording of the last 5

Flair 2xD

FLAIR 21D

The Flair 21D, 22D and 23DV fault
passage indicator is self- powered
by the measurement sensors.
A minimum 2A current is required
in the MV cable to start up the
Flair 21D display, an energy storage guarantees a 4 hours minimum autonomy.
The Flair devices have an output
contact for interfacing with a
SCADA system.

Flair 23DV has to be supplied
from 24Vdc to 48 Vdc for a permanent display operating and for the
outdoor lamp supply.(With a single
zero sequence CT, self powering is
not possible).

Flair 22D/23DV can be connected
to a voltage presence indicating
system (VPIS) provided with a voltage output (VPIS- VO). In this
case, for greater reliability, fault
detection is confirmed by voltage
absence without taking into
account the current.

The VD23 is a voltage presence
and absence detection relay.
It uses the VPIS V2- V0 as sensor,
and operates with a 24 or 48 Vdc
external power supply.

operation

: automatic frequency detection

Calibration:
At power up, the VD23 automatically detects voltage presence and
the network frequency, and then
performs self- calibration.
Measuring mode:
3 seconds after calibration, the
VD23 displays, by scrolling, the
percentages of the nominal
voltage detected on each phase

: calibration performed

Line- to - neutral voltages

Detection of Voltage presence:
When the voltage percentage
becomes greater than the set threshold for all the configured
phases, then the VD23 lights the
voltage presence indicator and
activates (or releases in inverted
mode) relay R1.

Detection of Voltage absence:
When the voltage percentage
becomes less than the set threshold for all the configured
phases, then the VD23 lights the
