Leakage current generation classification
Jul 25 , 2022
Generally, there are four types of leakage currents: semiconductor component leakage current, power supply leakage current, capacitor leakage current and filter leakage current 1. Leakage current of semiconductor components The very small current that flows through the PN junction when it is turned off. D-S is forward biased, G-S is reverse biased, and after the conductive channel is opened, curre...

Equipment required to calibrate current transformers
Nov 10 , 2022
1, Transformer calibrator: measure the error between the standard transformer and the transformer under test, display the working current. 2、Standard current transformer: used as a standard in transformer calibration, the accuracy is generally higher than the measured more than two levels, designed with multiple ratio taps, to adapt to different transformer calibration. 3, Booster: with the regula...
