| Abstract: | An accurate, quick and automatic measurement scheme is presented to solve the key problems in measuring DC resistance of main transformer windings. A portable instrument developed in this scheme is proved to be suitable, not only for resistance measurement of main transformer, and other devices with high inductance and micro ohm equipment, such as smoothing reactors, power transformers, as well as for measurement of contact resistance in relays, contactors and tap changers . |
