1. presentation of the VIP300
self-powered protective relay
n The VIP300 relay is designed for
use in distribution networks. It may be
used as MV/LV transformer
protection, protection at the incoming
point of industrial installations, and
also as branch feeder protection.
n The VIP300 provides protection
against phase-to-phase faults and
earth faults. The choice of tripping
curves and the multiple settings allow
it to be used in a wide variety of
discrimination plans.
The VIP300 is a self-powered relay,
energized by the current sensors; it
does not require any auxiliary source.
It actuates a Mitop release.

The phase protection has two
separately adjustable settings:
n the low setting may be chosen with
definite time or IDMT. The IDMT
curves are in compliance with the IEC
255-3 standard. They are of the
standard inverse, very inverse and
extremely inverse types.
The low setting may also be used
with the RI curve.
n the high setting is of the definite
time type.
earth protection
The earth fault protection operates by
residual current measurement: it uses
the sum of the sensor secondary
currents.
Like phase protection, earth
protection has two separately
adjustable settings.
LL and LH models
There are two models of the VIP300:
VIP300LL and VIP300LH, They differ
with respect to :
n operating range.
Refer to the chapter entitled "choice
of sensors and operating ranges".
n the VIP300LH has a table for
setting "equivalent time multiplier"
conversion on the front.
technical manual VIP300
sensors
In order for the specified
performances to be obtained, the
VIP300 relay must be used with the
following current transformers:
n CRa and CRb sensors:
(for RM6s 1998 and later).
n CSa and CSb sensors of the SFset
circuit breaker. The CSa and CSb
sensors have the same number of
secondary turns as the CRa and CRb
sensors respectively.
n 200/1 and 800/1 sensors of the
Ringmaster:
description
n The VIP300 relay is mounted in a
polycarbonate injected casing which
protects it against dripping water and
dusty environments.
The front is protected by a
transparent cover fitted with a sealing
joint. The cover may be lead-sealed
to prohibit access to the settings.
n Rotating selector switches are
used for setting. The phase setting
current and earth fault setting current
are set in amperes. This means that
the scale on the front must be
adapted to suit the sensor used. This
is done by positioning a "setting scale
label" on the relay at the time of
assembly.
n Connections are made on the back
using fast-on clips.
indication
Two indicators indicate the origin of
tripping (phase or earth). They stay in
position after a break in the relay
power supply.
Two LEDs (phase and earth) indicate
that the low setting has been overrun
and that the time delay is running.

phase protection
1. phase protection setting
zone
All the information concerning phase
protection is grouped together in the
dark zone of the upper half of the
front face.
2. setting overrun indicator
When the red indicator blinks, it
means that the phase protection low
setting time delay is running. When
this is the case, if the current does
not decrease, the relay will trip.
n for IDMT curves (SI, VI, EI), the
LED lights up when the current is
greater than 1.2 times the setting
current Is.
n for the IDMT curve (RI), it lights up
when the current is greater than the
Is setting.
n for the definite time curve DT, it
lights up when the low setting is
overrun.
F also refer to "indicator reset
button".
3. trip indicator
It is normally black and turns yellow
to indicate that the phase protection
has given a tripping order. It stays in
the same status, even when the relay
is no longer energized.
4. choice of setting current Is
The setting current setting range
depends on the sensor and range
used: the selector switch scale
should be adapted to suit the sensor
and range using the setting scale
label.
F also refer to "choice of sensors
and operating ranges" chapter.
6. choice of low setting I>
The setting is a multiple of the setting
current. It is only active for definite
time settings (selector switch 5 set to
DT).
If the tripping curve is selected with
IDMT (selector switch 5 set to RI, SI,
VI, EI), the selector switch has no
effect.
7. setting of low setting time
delay t>.
n If the tripping curve is of the
definite time (DT) type, the selector
switch sets the low setting time delay.
n If the curve is of the IDMT type (RI,
SI, VI, EI), the value displayed is the
tripping time for a phase current
equal to 10 times the setting current.
8. low setting time delay
multiplying factor.
In the x10 position, the time delay
displayed on selector switch 7 is
multiplied by 10.

- setting scale label -
- how to install the setting scale label -
8
a. setting scale label
n it should be mounted on the
VIP300 when it is assembled on the
circuit breaker. The label indicates
the scales for the phase setting
current and earth protection setting
current. It is inserted, from the top,
behind the transparent part of the
front face.
n each VIP300 comes with a set of
labels. Install the label that matches:
- the type of sensor used
- the VIP300 model
- the range used
n each setting scale label matches a
sensor and is printed on both sides
for each of the 2 ranges. The label
may therefore be turned around if the
VIP300 range is changed during the
service life of the installation.
F also refer to "assembly" chapter.
d. minimum operating current
The minimum operating current is the
phase current required for the relay to
be energized and operational. It is
printed on each setting scale label.
The value given on the setting scale
label is the single-phase rms
minimum operating current.
The minimum operating current is
always the lowest setting current
setting.
F note regarding minimum
operating current:
The VIP300 does not operate below
the minimum operating current level.
As a result, if the earth protections
are set below the minimum operating
current, they will only take effect
when there is phase current greater
than or equal to the minimum
operating current.
b. sensor and range indication
The text is printed on the setting
scale label.
When the label is installed in the slot,
the text is hidden by an opaque zone.
It is not visible to the user.
c. indicator reset button
The button is accessible when the
transparent cover is closed. When
the button is pressed, 2 actions are
triggered:
n it resets (black position) the 2
phase and earth trip indicators. When
the relay is no longer energized, it is
still possible to reset the indicators for
about 48 hours. After that time, they
may be reset after the VAP6 is
plugged in.
n it triggers the lighting up of the 2
red LEDs (about 3 sec). This
indicates that:
- the relay is energized. The indicator
lights up when the current is greater
than the minimum operating current.
- relay self-testing results are OK.
If one of the two conditions is not
met, the indicators do not light up.
This function may be used to carry
out a basic relay operation test.
e. VAP6 test plug
The test plug is exclusively designed
for connection of the VAP6 which is
used for fast, simplified relay testing.
The operation may be carried out
while the relay is operating since the
VAP6 and VIP300 provide the
possibility of testing with inhibition of
circuit breaker tripping.
F also refer to the "testing of the
VIP300 and use of the VAP6"
chapter.

assembly must be used together in
order to comply with the
characteristics, in particular:
- operation across the range
- response time
- accuracy
- short-circuit current behaviour
It is compulsory for the 3 sensors to

notes
1. Value given for three-phase
VIP300 power supply.
For single-phase operation, the
accuracy range is ± 10% or 0/+4A.
For the low setting, this does not
generally represent a real operating
situation. However, it may occur
during injection testing carried out
with single-phase.
The error is mainly due to the nonlinearity of the sensors and VIP300
input transformers with weak current,
the inaccuracy being accentuated
when the relay is only supplied by
one phase.
2. The accuracy is indicated for a
fault that occurs when the VIP300 is
already supplied by the current let
through by the circuit breaker. The
accuracy is indicated for sinusoidal
current. In the event of closing while
a fault is present, the tripping time
may be extended by:
+30 ms at 1.5 Is
+20 ms from 2 Is to 10 Is
+10 ms above 10 Is
18
3. Generally speaking, the accuracy
ranges of earth protection times and
settings are indicated for when the
VIP300 is supplied by current that is
greater than or equal to the minimum
operating current. The measurement
of a setting for earth protection with
single-phase supply is therefore not
significant if the setting is lower than
the minimum operating current.
5. In the following specific conditions:
- VIP300LL
- with CRa sensor
- wiring to x1 range
- if Ios < 8A
- if phase current < 20A
the setting and time delay
characteristics are:
- low settings: ±10% 0/+4A
- class not specified
4. Value given for three-phase
VIP300 supply. For single-phase
testing, the accuracy is ± 10% or
0/+4A. For the low setting, this may
occur when the earth protection is
tested with single-phase supply, and
no supply by the other phases.
6. Not applicable to test plug
7. Accuracy ± 10% or ± 1.5A.
The value indicates the guaranteed
minimum operating current for singlephase operation. With three-phase
oepration, it may be less than the
value indicated.
8. The tripping times indicated do not
include the mitop response time. Its
tripping time depends on its
mechanical load (for no load, its
tripping time is less than 5 ms)

The VAP6 is a portable unit that is
connected to the VIP300 to carry out
simplified testing.
The test can be carried out in the
following two cases:
- the VIP300 is already supplied by
the sensors.
- the VIP300 is not supplied. In this
case, the VAP6 batteries supply
power to the relay.
The test consists of:
- starting up the VIP300 central unit
self-testing sequence.
- injecting a stimulus to simulate a
phase fault.
- injecting a stimulus to simulate an
earth fault.
- checking tripping.
Frefer to the description of the test
in the section entitled "test sequence"
F the VAP6 is supplied by batteries.
Therefore the parts of the VIP300
that run on AC current are not
checked using this method (input and
supply circuits).
push-buttons
n battery test: if the batteries are
OK, the "on" indicator lights up while
the button is pushed.
n phase overcurrent: it sends the
phase protection test stimulus. The
stimulus is equivalent to 20 times the
setting current Is.
n earth fault: it sends the earth
protection test stimulus. The stimulus
is equivalent to 20 times the earth
setting current Ios.
n trip inhibition: press the "trip
inhibition" button if the VIP300 test
should be carried out without tripping
of the circuit breaker. Circuit breaker
tripping is inhibited while the ’trip
inhibition" button is pressed, even if
the tripping order results from a real
fault.
indicators
n on: indicates that the batteries are
operating. Also lights up when the
battery test is carried out by pressing
"battery test".
n test in progress: confirms sending
of the test stimulus to the VIP300.
n trip: it is used to test other relays in
the VIP range. It is not to be
considered for the VIP300 test. (it
lights up for a transient period when
the VIP300 sends a tripping order;
whether or not the circuit breaker is
inhibited).
"external mitop" output
It may be used to connect an
auxiliary mitop designed, for instance,
to stop a stop watch during operating
tests. The mitop is triggered at the
same time as the circuit breaker
mitop. It is not inhibited by pressing
the "trip inhibition" button.
batteries
n the batteries are normally
deactivated and are automatically
activated when the VAP6 is
connected to the VIP300.
They are activated in the following
cases:
- pressing the "battery test" button.
- direct connection to a VIP3X or
VIP5X relay.
- connection to the adapter cord
designed for testing of the VIP1X or
VIP2X relays.
n to install or change the batteries,
open the unit by removing the 4
screws on the bottom of the unit. Be
sure to use the correct polarities.

8. testing of the VIP300 and use of the VAP6 (cont’d)
VAP6 test sequence
The test may be carried out with or
without current in the sensors. During
the test operations, all the VIP300
settings are effective; the relay
should perform in accordance with
the settings. During the test, the relay
remains operational and will give a
tripping order in the event of a fault,
unless the "trip inhibition" button is
pressed.
n connect the VAP6 to the "VAP6
test plug". The VAP6 batteries are
activated and the "on" indicator lights
up.
n press the VIP300 "reset" button.
- if the 2 "trip" indicators were yellow,
they become black.
- the 2 red I> and Io> indicators of the
VIP300 light up for about 3s to
indicate that the central unit has
correctly performed self-testing.
n press the "trip inhibition" button if
the test should be carried out without
tripping of the circuit breaker.
Fbe sure to continue pressing the
"trip inhibition" button throughout the
time it takes to send the stimulus.
technical manual VIP300
n press the "phase overcurrent"
button to send the phase protection
test stimulus.
- continue pressing the button
throughout the duration of the
stimulus. The stimulus represents
about 20 times the setting current Is.
- the VAP6 "test in progress" indicator
lights up to confirm the sending of the
stimulus to the VIP300 relay.
- the red "I>" indicator of the VIP300
blinks during the time delay period.
- then the VIP300 phase "trip"
indicator turns yellow.
- the circuit breaker trips if it is not
inhibited.
F if the "phase overcurrent" button is
held down after tripping, the VIP300
starts the time delay/tripping cycle
again; this is normal operation.
In that case:
- the VAP6 red "trip" indicator lights
up for a transient period each time
there is a trip.
- depending on the time delay setting,
the VIP300 red "I>" indicator may be
off or blink rapidly and/or in an
irregular manner.
n press "earth fault" to test operation
of the earth protection. The stimulus
injected is equal to 20 times the
setting current Ios. Use the same
procedure as for the phase protection
test.
n disconnect the VAP6.
In order to save batteries, do not
leave the VAP6 connected to the
relay unnecessarily.
