Abstract
The power system monitoring & protection normally makes use of different types of relays. These relays basically operate with signals drawn from system such as voltage & current those are sensed in the current practice by using current transformer & capacitive voltage transformer. These devices suffer problems such as ratio & phase error along with saturation which affects the performance of relay & hence fail to operate. This limitation can be overcome by rogowski coil having air core. This paper while addressing the problems related to current transformer & capacitive voltage transformer using PSCAD software also presents effectiveness of rogowski coil by experimental validation.
