Product Description
Features
- Software based design
- Programmable time current characteristics
- Choice of four IDMT curves
- Draw out case
APPLICATIONS
The relay provides time graded phase and earth
fault protection of Genrators, Transformers, feeder,
capacitors etc.,
PRINCIPAL OPERATION
The relay measures the line current from each of the phases and if exceeds the set operating current, then relay extends a trip signal after the operating time. The relays operating time is determined by selecting one of the four inverse time current characteristics. The relay has facility to active / inhibit the high set protection feature. The relay output contacts are self reset type. Relay operation without any fault current is determinated by trip test facility.
