Generator Rotor AC Impedance Testing Instrument , Turn-to-turn Short Circuit Characteristic Testing
I. Product Description and Why select the test device :
The Turn-to-turn short circuit of the generator rotor winding is a common fault in power system. When the fault occurs, the current of rotor and the temperature of windings will increase, that limits the output of the generator, even affects the normal operation of the generator. The interturn short circuit is usually determined by measuring the AC impedance and power loss of the generator rotor windings. The traditional measuring method is to use a lot of test instruments to measure after assembling in the field. This method which requries a lot of test equipment to form a measurement system has the shortcomings of cumbersome, time-consuming, tedious sorting data and lower measurement accuracy.
Model FK-ZKC 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.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.
