PROGRAMMABLE DIRECTIONAL INVERSE TIME CURRENT RELAY JRP 011

OVERVIEW

    Features

  • Software based design
  • Programmable time current characteristics
  • Choice of four curves
  • Selectable characteristic angle
  • Programmable directional / 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.,

PROGRAMMABLE DIRECTIONAL INVERSE TIME CURRENT RELAY JRP 011

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 . Relay operation without any fault current is determined by trip test facility.
