'PROTON's PHASE CORRECTOR RELAY' offer following protections along with 3 digit display showing R-Y,Y-B,BR voltages in scanning mode with precise accuracy.
LOW/HIGH voltage tripping to ensure trouble free running of 3-phase Loads. Single phasing & Unbalance protection. Phase correction RELAY 'R2' which operates only when phase sequence changes.
- Supply voltage : 3 Phase 415 VAC, 50 Hz (R, Y, B &N) (No auxiliary supply)
- Output Contacts : L1-Normal Sequence, L2 Reverse Phase Sequence
- Indications : FAULT (UV, OV): RED LED,
- RELAY ON : GREEN LED
- Relative Humidity : 10 to 95% RH
- Mounting : Din Rail
- Dimensions : 55(W) X 75(H) X 110(D) mm.
- Keys :
- SET : SET key, Press to enter into SET Mode
- INC : Upward Arrow key, Press to increment the set point.
- DEC : Downward Arrow key, To Decrement the set point.
- Working :
- 1] If the Input supply is within the range of the fault limits then On Timer starts decrementing on display & after Set On Time over Relay will be ON with RLY indication glowing.
- 2] If OV, UV, Spp, Unbalance occurs in the supply then Relay will be OFF after the trip delay of that particular fault.
- 3] If any Phase to Phase Voltage increases above OV set point, Relay will trip after trip delay (<100 ms) over. If that particular phase to phase voltage reduces below (OV set point - 10 V), Relay will be ON after the set reset delay over.
- 4] If any Phase to Phase Voltage increases/reduces Above/below the UB set point compared to other two Phase to Phase voltages, Relay will trip after set trip delay over. If that particular phase to phase voltage reduces/increases below/above (UB set point -/+ 10 V), Relay will be ON after the set reset delay over
- 5] If any of the Phase fails, Relay will trip after trip delay (<100 ms) over. If all phases are present, Relay will be ON after the set reset delay over.
- 6] If Phase sequence is changed to R-B-Y/Y-R-B/B-R-Y, Relay (R2) will be ON. If phase Sequence is corrected to R-Y-B, Relay (R1) will be ON after the set reset delay over. UB/SPP, UV, OV.
