Product Description
Features
- Software based design
- Wide setting range
- Wide auxiliary supply
- Low burden
Application
The relay provides earth fault protection of Generators,
Motors, Transformers, Capacitors, Feeder etc.
PRINCIPLE OF OPERATION
The relay provides earth fault protection for power systems. Relay operating time is determined
by the set definite time. The relay measures the current from input CT and if it exceeds the set
threshold, it extends a trip signal after the operating time, which is determined by set definite
time. The relay output contacts are self reset type. TEST button facilitates testing of relay contacts
for trip and alarm circuits.
