PROBLEM TO BE SOLVED: To provide an electric energization testing system that serves to enhance convenience and safety in electric energization testing of generator current transformers.;SOLUTION: In an electric energization testing system, by causing a multi-core cable 5 formed by passing a single core wire back and forth a plurality of times from one end to the other to penetrate the primary side iron core of a generator current transformer 2 and connecting a plurality of core wires in linkage, a state similar to what results from winding a testing wire 3 around the primary side of the generator current transformer 2 a plurality of times is achieved; in this state, a current for subjecting the generator current transformer to an electric energization test is applied from a voltage-current generator 4 through both ends of the testing wire 3, a current phase arising on the secondary side of the generator current transformer 2 is measured with a measuring instrument 20, and the soundness of the generator current transformer 2 and circuits around it is thereby checked.;COPYRIGHT: (C)2015,JPO&INPIT
