Abstract: A method, system and computer readable medium for determination of distance to an electrical fault within a device. A signal generator excites the device with an electrical input signal. The device comprises an open circuited electrical transmission line. A frequency domain analyzer analyzes part of the signal reflected from the device for determination of the locations of resonant frequency of the signal within the device. A computer calculates the distance to the fault within the device, based on the resonant frequency.
