The KDFZ-A generator rotor AC impedance tester is a relatively new enhanced AC impedance tester launched by our company. The instrument adopts the latest high-speed microprocessor technology, with stronger functions, superior performance, and more convenient use. Used for measuring the rotor AC impedance and characteristic curves of various synchronous generators under dynamic and static conditions in most capacity generator sets. It is a specialized instrument for determining whether there is a turn to turn short circuit in the rotor winding of a generator. It can automatically or manually (unidirectionally or bidirectionally) measure parameters such as voltage, current, impedance, power, phase angle, etc. of the rotor winding.

The KDFZ-A generator rotor AC impedance tester has the following functions and features:
1. Rotating the mouse makes operation more convenient.
2. There are two methods to choose from: fast automatic measurement and manual selection measurement.
3. Large screen Chinese menu interface, real-time display of test data and curves.
4. Storage of data, built-in micro printer, real-time and fast printing of test data and characteristic curves.
5. Automatically adjust the protection action value based on experimental parameters to ensure equipment safety.
6. It can also be used for no-load and short-circuit tests of single-phase transformers, as well as volt ampere characteristic tests of voltage (current) transformers and arc suppression coils.
