DIFFERENTIAL RELAYS
Transformer overfluxing Relay JNF 020

Numerical software based design
LCD display of V, Hz, V/F
High accuracy
Definite time for alarm
Inverse time for trip
Independent output for alarm and trip
Trip test facility
Restricted earth fault Relay JRD 011

This is a current operated, software based, differential relay
Works on the high impedance principle.
An external series stabilizing resistor is used with this relay to make it a voltage operated relay.
The voltage setting of the relay is adjusted to be higher than that developed by the current transformers under maximum external fault conditions.
High stability on external faults
Insensitive to currents at harmonic frequencies
Trip test facility
Compact size - 144 x 144 x 110 mm
