Project Description
Product Features:
Automatic collection, measurement, display, storage and printing of all measurement parameters and impedance characteristic curves (voltage, current, impedance, power, frequency, equipment number, time, etc.).
Automatically collect the real-time speed of the generator (requires the support of the speed sensor), and can measure the rotor AC impedance and its characteristic curve of various synchronous generators in dynamic and static conditions.
Super long range, can measure all generator rotor AC impedance and characteristic curve automatically and manually.
Comes with a miniature printer, which can print AC impedance test reports and AC impedance characteristic curves in real time.It can also be used for no-load and short-circuit tests of single-phase transformers.
The generator rotor AC impedance tester is a special instrument for judging whether the generator rotor winding has an inter-turn short circuit. It also ac impedance test generator rotor. It can measure the voltage, current, impedance, power, speed and other parameters of the rotor winding automatically and manually (one-way or two-way).
LTFZ generator rotor AC impedance tester adopts advanced high-speed microprocessor technology, which is more powerful, superior in performance, and more convenient to use. It has the characteristics of high reliability, easy operation, high test accuracy, compactness and lightness. At present, it is at the leading level in the country.
Built-in large-capacity memory, can store test data, and upload to PC via standard industrial communication interface (RS232), use the random software developed by our company to realize data download, automatically generate and edit typical test reports, which is convenient for technical management and archiving .
It has perfect over-voltage and over-current protection functions, in which the over-current and over-voltage protection value is automatically adjusted according to the setting of the test parameters, which is simple and can ensure the safety of the equipment under test.
