Product Description
Features
- Software based design
- Wide Current Setting ranges
- Draw - out case
Application
The relay provides time graded phase and earth fault protection of Generators, Transformers, Feeder, capacitors etc.,
PRINCIPLE OF OPERATION
The relay measures the line current from each of the phase and if it exceeds the set threshold, then relay extends a trip signal after an operating time, The relay’s operating time is determined by selecting one of the four inverse time charcteristcs. The relay has facility to active / inhibit the high set protection feature. The relay out contacts are self reset / Hand reset type. Relay Operation without any fault current is determined by trip test facility.
