The insulating oil dielectric strength tester calibrator is a professional instrument designed for the measurement and calibration of insulating oil dielectric strength tester in electric power test and measurement Institute. The instrument can calibrate the performance parameters such as breakdown voltage, boost rate and waveform distortion of insulating oil dielectric strength tester, and automatically give the test result report. The device takes the voltage at the moment of breakdown of the insulating oil dielectric strength tester as the detection basis and calculates the error of the instrument. Compared with the previous steady-state calibration method, it is more intuitive, accurate and effective.
