IPR96D Ground Protection Relay
6.2
Instruction Manual: IPR96D GBM 24/11/2020
System Setup
Max Switching Current
Value
ENABLED
RANGE: ENABLED; DISABLED
Indicate whether you want to enable or disable a current limit beyond which the
relay must not activate the TRIP output to avoid damaging the switching device
(useful when there is a switch/disconnector instead of a Circuit Breaker). In case
of Circuit Breaker, make sure to select DISABLED.
System Setup
Max Switching Current
Value
400 A
RANGE: 50
5000
STEPS: 10
The selected value indicates the current limit described in the screen above.

If Max Switching Current = ENABLED
System Setup
Breaker Failure Relay
Value
- - -
It allows selecting the output signaling the discrepancy between the trip command
sent by the protection relay and the signal received at the BREAKER STATUS
input from the circuit breaker or disconnector auxiliary contact.
This error information signals that the trip command has not provoked the opening
or that the auxiliary contact (52a) does not operate properly.
Disable this function in case of no connection between 52a auxiliary contact and
BREAKER STATUS input.
To disable the function, select "- - - ".
System Setup
Breaker Failure Delay
Value
1000 ms
RANGE: 10
2500
STEPS: 10
Delay for the circuit breaker auxiliary contacts to signal the opening. If a correct
reply is not obtained in this delay, an event for circuit breaker failure will be
displayed and the selected contact will activate.

Value
- - -
Select the relays to be activated when reaching the max. number of mechanical
operations set in the next Line.

Mech. Operations
Max
Value
3000
RANGE: 5
9995
STEPS: 5
This value represents the granted quantity of mechanical operations carried out
by the circuit breaker and the event indicates that maintenance is required.

Following the intervention of the Breaker Failure function, once the circuit breaker has been repaired, it will be necessary to
reset the IPR96D (if still in
Tripped
state) before proceeding to close the circuit breaker.
