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, Feeder etc., and where definite time protection is required.
Principle of Operation
The relay provides single pole over current protection for power systems. The Relay operating
time is deter mined by the set definite time. The relay measures the current from input CT and if
it exceeds the set thresh old, 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.
