Product Description
Features
- Software based design
- Programmable time current characteristics
- Choice of four curves
- Selectable characteristic angle
- Programmable directional element / Non-directional element
- Draw - out case
Application
The relay provides time graded phase and earth fault
protection of Parallel transformers, Transformer feeders,
Parallel feeders, ring main system etc.,
PRINCIPLE OF OPERATION
The relay measures the line current from each of the phases or earth fault 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 . Relay
operation without any fault current is determined by trip test facility
