Generator rotor AC impedance tester is a special instrument used to determine whether there is an inter-turn short circuit in the generator rotor winding, which can manually and automatically measure many parameters of the generator rotor, such as voltage, current, impedance, power and speed. RDZZ-605 engine rotor AC impedance tester adopts advanced high-performance microprocessor technology, which is more powerful, better performance and more convenient to use. The tester has a series of characteristics such as high reliability, convenient operation, high test accuracy, compact structure and light weight, and is currently at the leading level in China.
Product Description
The RDZZ-605 Generator Rotor AC Impedance Tester is designed to check generator rotor windings for possible inter-turn short circuits. It can measure key rotor parameters, including voltage, current, impedance, power, and speed. Both manual and automatic measurement modes are available, making routine testing easier.
The tester uses a high-performance microprocessor for data processing and control. Its compact design and low weight make it convenient for on-site use, while the measurement system provides stable and accurate test results. The RDZZ-605 is also designed for simple operation and reliable long-term use, making it suitable for generator rotor inspection and maintenance.

Product Features
1. Rotor AC Impedance Testing – Measures AC impedance and plots characteristic curves for synchronous generators and asynchronous motor windings while the rotor is stationary.
2. Two Test Modes – Users can switch between automatic and manual measurement modes according to the test requirements.
3. Clear Data and Curve Display – The large-screen menu makes operation simple and shows test values and curves in real time.
4. Data Storage and Printing – Test results can be saved for later review, while the built-in micro printer can print measurement data and characteristic curves on site.
5. Automatic Safety Protection – The tester adjusts the protection threshold according to the test parameters, helping protect the equipment during measurement.

Why Is Rotor AC Impedance Testing Important?
AC impedance testing is used to check the electrical condition of generator rotor windings and help identify possible inter-turn short circuits. By measuring impedance and recording the characteristic curve, technicians can compare different test points or compare current results with previous records.
The test can be used for routine maintenance, commissioning, troubleshooting, and inspection after rotor repair.
How Should the Test Results Be Evaluated?
A single impedance value should not be used to make a final fault diagnosis. Technicians should review the impedance, voltage, current, power, and characteristic curve together.
If the curve shows an unusual change or differs significantly from previous test records, further inspection may be required. Test conditions such as voltage, frequency, rotor position, and winding temperature should also be considered when comparing results.
Key Safety Points
Before testing, make sure the generator is properly isolated and the rotor is stationary. Check all test connections before applying voltage and follow the generator manufacturer's specified test procedure.
After testing, discharge and ground the winding as required before disconnecting the test leads.
