An effective method of detecting inter-turn short circuits on round rotor windings is described Shorted-turns can have significant effects on a generator and its performance A method of detecting inter-turn short circuits on rotor windings is described The approach used is to measure the rate of change of the air-gap flux density wave when the rotor is at operating speed and excitation is applied to the field winding The inter-turn short circuits sensor for synchronous generator's field winding has been developed The sensor, installed in the generator air-gap, senses the slot leakage flux of field winding and produces a voltage waveform proportional to the rate of change of the flux For identification of reliability for sensor, a inter-turn short circuits test was performed at the West-Inchon combined cycle power plant on gas turbine generator and steam turbine generator This sensor will be used as a detecting of shorted-turn for field winding of synchronous generator The purpose of this paper is to describe the design and operation of a sensitive inter-turn short circuits detector In this paper, development of inter-turn short circuits sensor for field winding of synchronous generator and application in a field.<br/>
