Protective Relay Settings - Pangonilo
pangonilo.comThis is because the time delay T is the operation time of the relay when the current reaches 10Is. Hence, the time delay of the IDMT tripping may be set either by: T (s): operation time at 10Is or TMS: where TMS = T/ β Example: For 100/5 CT with P.S at 100%, TMS=0.1, using the standard inverse 3/10 curve, the SEPAM relay will be set

www.gegridsolutions.com18 FUNDAMENTAL RELAY-OPERATING PRINCIPLES AND CHARACTERISTICS Time delay is obtained in induction-type relays by a "drag magnet," which is a permanent magnet arranged so that the relay rotor cuts the flux between the poles of the magnet, as shown in Fig. 4. This p roduces a retarding effect on motion of the rotor in either di rection.
