Abstract: PURPOSE: A method for measuring a partial discharge during the drive in the stator winding of a high pressure rotator is provided to economically and reliably monitor the insulation status in the stator winding of the high pressure rotator. CONSTITUTION: A method for measuring a partial discharge during the drive in the stator winding of a high pressure rotator includes the steps of: detecting the zero point and dividing(S304) the partial discharge signal inputted thereto into a positive(+) and a negative(-) partial discharge signals, dividing(S305) the divided signals into dual paths, detecting by dividing one set period by a predetermined plurality of unit intervals on the phase axis in response to each of the signal on the dual paths, detecting/maintaining(S307) the maximum value by the divided period unit based on the detected phase, implementing(S308) the analog to digital conversion therefor, and alternately performing the above step to each of the signals on the dual path on the phase axis and analyzing the insulation status of the stator winding based on the converted digital data.

Abstract: PURPOSE: A sensor for measuring temperature, partial discharge, and magnetic flux of a winding type power device is provided to form a resistance temperature detector complex sensor by using only a single resistance temperature detector wire rod. CONSTITUTION: A sensor for measuring temperature, partial discharge, and magnetic flux of a winding type power device includes a resistance temperature detector wire rod and a plurality of signal lines. The signal lines are connected to both ends of the resistance temperature detector wire rod(200). An epoxy is molded around the resistance temperature detector wire rod. A diameter and a length value of the resistance temperature detector wire rod are decided to form the Ampere turn enough for maintaining a resistance of 100 ohms and measuring magnetic flux.
