© 2016 IEEE. This paper deals with partial discharge (PD) location in a power module by measuring electromagnetic (EM) wave of PD using four loop sensors. As the distance between the sensor and PD source decreases, the peak to peak magnitude of the first wave of detected EM wave was found to increase using four sensors array. An attempt is made to locate PD source using output electromagnetic waves detected four loop sensors by the time of flight method. As a result, the present method is found to allow PD location with location identification error of 5 mm.
