Abstract

The invention discloses a digital calibration system of partial discharge test equipment. The digital calibration system is characterized in that the system comprises a device to be tested, and a digital calibrator and a measurement and control computer of the partial discharge test equipment which is connected with the device to be tested, wherein the output end of the digital calibrator of the partial discharge test equipment is connected with the measurement and control computer; the measurement and control computer compares the collected waveform and data measured value with the standard value output by the digital calibrator to perform analysis and calculation and obtain the error of the measured value and the standard value, outputs the error value, and measured value and standard value to a data outputting machine so as to realize the calibration of the partial discharge test equipment. In the system of the invention, the wide measuring range which is 1-10000pc, the high accuracy standard pulse calibrator and a high speed data acquisition card with 12 bits of precision are adopted to ensure the calibration accuracy to reach + / -2%.

Description

technical field [0001] The invention discloses a calibration system for calibrating partial discharge testing equipment and a digital calibration system for field partial discharge testing equipment. Background technique [0002] With the continuous development of power electronic systems and high-voltage electrical products, and with the upcoming revision of the IEC standard on "Partial Discharge Measurement", the measurement and calibration of the test system for partial discharge tests is proposed to be more stringent and stricter. Meticulous and new requirements, especially in the range of 1-10000PC, the realization of a digital standard system with a calibration accuracy better than ±2% or higher needs to be established urgently. [0003] The currently used calibration method is to calibrate and open the cover plate of the calibrator of the partial discharge test system to be calibrated, and measure the square wave voltage value U 0 , and then measure the capacitance v...
