Protective Relay Settings - Pangonilo
pangonilo.comThe curve equations are given in the chapter entitled "IDMT protection functions" Figure 3 shows that for the Type 1 curve, the relay will activate at 1 X Is, after a certain time delay. However, for Type 1.2 curve, the relay will only activate at 1.2 X Is. The Type 1.2 curve characteristic is in accordance with BS
