Product overview
EDHNZ-3 generator rotor AC impedance tester is the latest AC impedance tester developed by our company on the basis of EDHNZ- 1 and EDHNZ-2. It adopts "one-button shuttle" technology (rotating mouse). Adopt high-speed synchronous test system; The display and printing functions of AC impedance characteristic curve are added, and the functions of downloading data and editing test report can be realized online by PC, which increases the test capacity and is suitable for all capacity generator sets.
The instrument adopts the most advanced high-speed microprocessor technology, which is more powerful, superior in performance and convenient to use. At present, it is at the leading level in China.
According to the requirements of users, we can customize ultra-low harmonic safety isolation voltage regulators and reactive power compensation devices with various capacities and output voltages. The total capacity is 30KVA and the weight is only 20Kg!
Using EDHP-3 electric parameter matcher of our company, we can measure the parameters such as AC impedance of single pole of hydrogenerator. This function is exclusively owned by China!
Functions and characteristics
◆ High-speed measurement of AC impedance of various synchronous generator rotors and their dynamic and static characteristic curves.
◆ Fully automatic (unidirectional or bidirectional) acquisition, measurement, display, storage and printing of all measured parameters (voltage, current, impedance, power and frequency).
◆ Imported high-quality "one-button shuttle" (rotating mouse) does not need buttons, making the operation more convenient.
Built-in super-capacity memory can store 6400 groups of data, which can be uploaded to PC through RS232 communication interface, so as to download data and automatically generate editable test reports, which is convenient for technical management and archiving.
◆ Fast automatic measurement and arbitrary manual measurement can be selected.
Imported high-brightness blue large-screen graphic LCD display, full Chinese menu prompt operation, simple and convenient. (With contrast adjustment function, the best visual effect can be obtained in various environments)
Self-contained micro printer can print test data and characteristic curve quickly in real time.
◆ Perfect overvoltage and overcurrent protection function. Automatically adjust the protection action value according to the test parameters to ensure the safety of the equipment.
◆ It can also be used for no-load and short-circuit tests of single-phase transformers and volt-ampere characteristic tests of voltage (current) transformers and arc suppression coils. It can also measure the AC impedance of various synchronous and asynchronous motor windings.
◆ All-metal standard industrial chassis is adopted, which conforms to national standards and has strong anti-interference ability. The electromagnetic field interference in the AC impedance test environment of generator is very serious, especially in the out-of-bore test. Because the magnetic field is open, the instruments in the non-metallic cabinet may be disturbed, which will bring great errors to the measurement data. )
The equipment adopts the latest test system, and the efficiency of data processing (passing the test) is more than 4 times faster than that of similar products, ensuring the speed, reliability and accuracy of data processing;
