Safety Precautions
Warning
Under certain fault conditions, high voltages can be conducted into the fault indicator
enclosure through the CT, remote indicator, or the auxiliary relay cables. All parts
within the enclosure should be handled as if carrying dangerous voltages.
u This product must be used only by qualified personnel practicing
applicable safety precautions. Do not use the product, if damaged.
Use extreme caution during the installation and use of the indicator as high
voltages and currents may be present in the circuit.
¿ Do not install the product on live conductors
¿ Wear protective clothing and gloves as required
¿ Always de-energize circuit before installing the current sensor & indicating unit
¿ Always inspect the current sensor, indicating unit and all leads for
damage before using the product
¿ Ensure that the current sensor is installed at earth potential on the
HV cable system
¿ Ensure that the current sensor is installed on screened part of the cable system

Introduction
Features
CSFPI-Short Circuit & Earth Fault Passage Indicator is designed to detect
and indicate Earth fault and Short circuit on a cable system, which can be
used in RMU networks with one input / open ring arrangement. The unit will
indicate a fault condition by operating alarm contacts for remote indication
and by illuminating integral LEDs when current is detected above present trip
current settings. Fault current is sensed by cable mounted sensor, which
gives signal to Front display unit. Sensor must be mounted on screened cable
and can be retrofitted on the cable.
l Programmable Short circuit pickup level (wide range 100A to 1200A)
l Programmable Earth fault pickup level (wide range 10A to 150A)
l Indication of permanent earth-faults by blinking of Earth-fault LED
l Indication of a short-circuit by blinking of the Short-circuit LEDs
l Programmable response delay for short-circuits and Earth-faults
l Up-to Three potential free contacts to indicate earth-fault, short-
circuits & low battery remote indication
l Various Reset option for Fault Reset
l Reset through Potential free input & AC/DC voltage
l Reset manually by push button
l Reset automatically by a field configurable timer (Hour)

Installation of the Sensor
Installation of the Indication Unit
While installing the sensors, ensure that no current is flowing through the
cables. They are mounted around the high voltage cable and fixed with
clamp and screws.
To install this sensor, the fixing screws have to be loosened from the
bracket. After that, the open Steel bracket has to be mounted around the
cable core. Once Steel bracket has been mounted, screw the sensor case
to the bracket frame again. Please note Fixing Screws have to be
tightened strongly enough, so that the bracket surface is tight-fitting with
the steel bolt of the sensor case.
Next, put the sensor in a fixed position on the cable, by locking the screw
on the back of the steel bracket in case of short circuit sensor (or) by
clamping it with the help of a cable tie for earth sensor.
The FPI indicator unit is for panel mounting. The unit is fitted on to the
panel with the help of fixing clip provided.
Now connect the wires coming out of sensor to the FPI indication unit as
follows:
Connect Red & Black wires of L1 Phase, L2 Phase, L3 Phase & Earth
sensor respectively to input terminals - 1 & 2, 3 & 4, 5 & 6, 7 & 8 of
indication unit.
•Ensure that the current sensor is installed at earth potential on the
HV cable system
•Ensure that the current
sensor is installed on the
screened part of the cable
system
•Sensor should be installed
on shielded cable (*)
•Loose screw can create open circuit
in sensor and may result blast of the sensor.
•Sensor secondary need to be terminated to FPI terminal.
Open terminal may can result blast of the sensor
