Impedance Tester - Yangzhou Darui
Darui Electric recommends for you
☆Impedance Tester adopts a split structure with an external voltage regulator, allowing users to flexibly choose the regulator as needed;
☆Can quickly measure the AC impedance and power loss of synchronous generator rotors both inside and outside the bore, and at different speeds;
☆Can also be used for single-phase short-circuit and no-load characteristic tests of power transformers;
☆Can also be used for volt-ampere characteristic tests of voltage transformers and current transformers;
☆Can simultaneously measure parameters such as AC voltage, AC current, active power, and frequency;
☆Automatic test function: During the test, it can automatically track sampling in real time based on preset test parameters, automatically process and store test data;
☆According to different user requirements, when testing the AC impedance of generator rotors, two test methods are provided: "one-way test" and "two-way test":
One-way test------Only tests in one direction during the voltage increase process of the voltage regulator;
Two-way test------Can test separately during both the voltage increase and decrease processes of the voltage regulator;
☆Has interrupt measurement function: During impedance measurement, the measurement process can be manually interrupted, and the data before the manual interruption will be automatically saved;
☆Data storage function: Can store up to 200 data files. If used solely for storing AC impedance test data, it can store up to 7280 data points; stored data can be preserved for more than 10 years;
☆Data and curve display function: Can display current and historical measurement data and test curves;
☆Printing function: Can instantly print measurement data and curves with Chinese labels. This unit uses a thermal printer, which has the characteristics of long life and quiet operation;
☆Has a "zero value" detection function for the output voltage of the voltage regulator. Ensures that the voltage regulator starts increasing voltage from zero at the beginning of each measurement, thus ensuring the test is safe and smooth;
☆Uses a 1/4VGA (320X240) color LCD screen, with full Chinese menu prompts, clear and intuitive interface;
☆Uses an advanced rotary encoder, making operation more convenient, simple and reliable;
☆ Complete overvoltage and overcurrent protection;
☆Non-volatile calendar and clock functions;
☆Measurement data upload function: Through the RS232 interface, measurement data can be uploaded to a PC for technical management and data archiving.
