KDZK-F Generator rotor AC impedance tester Generator rotor impedance tester Impedance tester

Core Application Scope

The instrument is a specialized device used to detect inter-turn short circuits in generator rotor windings. By measuring parameters such as the rotor winding's AC impedance and power loss under different conditions, and plotting its characteristic curves, it diagnoses the health status of the rotor winding.

Specific Application Scenarios

1. Power Systems and Power Generation Enterprises:

   • Synchronous Generator Testing: Widely used in thermal, hydro, nuclear, and renewable energy power plants (such as wind power) for routine maintenance and condition assessment of synchronous generators of all capacities.
   • Asynchronous Motor Testing: Can also be used to measure the rotor AC impedance of asynchronous motors.

2. Test Conditions:

   • Static Testing: Measurements are performed when the generator is shut down.
   • Dynamic Testing: Measurements are taken while the generator is rotating (at different speeds) to obtain a more comprehensive impedance characteristic curve.

3. Multi-Function Extended Applications: The instrument is typically multifunctional and can also be used for:

   • Single-Phase Transformer Tests: Performing open-circuit and short-circuit tests.
   • Transformer Tests: Measuring the volt-ampere characteristics of voltage transformers (VT) and current transformers (CT).
   • Arc Suppression Coil Tests: Measuring the volt-ampere characteristics of arc suppression coils.

4. Other Application Fields:

   • Large Manufacturing Enterprises: Used for maintenance of large motor equipment within factories.
   • Research Institutions: Used for research and testing related to power systems.

In summary, the Generator Rotor Impedance Tester is primarily used in power systems, various power plants, and large industrial enterprises for preventive testing and fault diagnosis of rotor windings in critical rotating equipment such as generators and motors, ensuring safe and stable operation of the equipment.
