The virtual load method-based generator rotor alternating current impedance tester calibration device includes a first high-accuracy meter, a high-stability precise program-control source, a second high-accuracy meter, a digital display and man-machine interface module, a current output terminal which is connected with the first high-accuracy meter and the high-stability precise program-control source respectively, as well as a voltage output terminal which is connected with the high-stability precise program-control source and the second high-accuracy meter respectively. With the virtual load method-based generator rotor alternating current impedance tester calibration device of the invention adopted, defects of large manual workload, high misoperation rate and high calibration difficulty in the prior art can be eliminated. The virtual load method-based generator rotor alternating current impedance tester calibration device has the advantages of small manual workload, low misoperation rate and low calibration difficulty.

Description

technical field [0001] The invention relates to the technical field of detection of power electronic equipment, in particular to a calibration device for a generator rotor AC impedance tester based on a virtual load method. Background technique [0002] Generator rotor AC impedance tester is a comprehensive measuring instrument used to measure and analyze the AC impedance of generator and condenser rotor windings. Through the specially designed measurement circuit, the parameters of AC impedance, power, frequency and other parameters of rotor windings can be realized. Automatic measurement. In the calibration, verification and detection of AC impedance testing instruments, the detection of the measurement function of the transition process (including transition resistance and transition time) is the most important detection item. In recent years, with the development of science and technology, the integrated generator rotor AC impedance tester has appeared on the market, pr...
