Product Description
Features
- Software based design
- Programmable time current characteristics
- Choice of four IDMT curves
- Draw out case
- Wide range auxiliary supply
- Low burden
APPLICATION
The relay provides time graded phase protection of Generators, Transformers, Feeder, capacitors
etc.,
PRINCIPLE OF OPERATION
The relay measures the line current from each of the phases 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 characteristics. The relay has facility to active / inhibit the
high set protection feature. The relay output contacts are self reset / Hand reset type. Relay operation without any fault current is determined by trip test facility.
