ZFZK-502B generator rotor AC impedance tester


Generator rotor winding inter-turn short circuit is a common fault in power system. When this kind of fault occurs, the rotor current increases and the winding temperature increases, which limits the output of the generator and affects the normal operation of the generator in severe cases. Inter-turn short circuit is usually determined by measuring the AC impedance and power loss of the generator rotor winding. The traditional measurement method is to use multiple test instruments and meters to measure after on-site assembly. This method, which requires a lot of test instruments and meters to form a measurement system, has the disadvantages of heavy test equipment, time-consuming and laborious, cumbersome data sorting and low measurement accuracy.
