Idmtl relays
Web17 sep. 2024 · The IDMT relays operate as inverse time relay i.e., there exists an inverse relationship between time and current for lower values of fault current. While for higher values of fault current the relay acts as the definite time relay where the operating time is independent of fault current. Web17 feb. 2024 · Similarly, it may be important to check the relay characteristic over a range of input currents to confirm parameters for an overcurrent relay such as: ... Why cant we use PI Test Set to test the functionality of IDMTL Relays in tripping the Circuit Breaker? Reply. Biraj Baruah. Nov 09, 2024.

The current I 1 from the line CTs, sets up a magnetic flux A and also induces a current I 2 in the secondary winding which in turn sets up a flux in B. Fluxes A and B are out of phase thus producing a torque in the disk causing it to rotate. Now, speed is proportional to braking torque, and is proportional to ...
