Wuhan GDMK Electric Co., Ltd.

Overview:

Generator Rotor AC Impedance Testing Instrument is a special instrument for determining whether the turn-to-turn short circuit exists in the generator rotor winding, and can manually and automatically (unidirectionally or bidirectionally) measure many parameters of the generator rotor such as voltage, current, impedance, power and rotating speed.Generator Rotor AC Impedance Testing Instrument is the latest enhanced AC impedance tester launched by our Company. The instrument adopts the state-of-the-art high speed microprocessor technology with more powerful functions, preferable performances and more convenient use. The Tester has a series of characteristics such as high reliability, easy operation, high test precision, being compact and lightweight and etc., and currently is in the domestic leading level.
