Page 4: I.scope Of Application
I.Scope of application HZZGF-Z series intelligent DC high-voltage generators are mainly used for DC withstand voltage tests on high-voltage electrical equipment such as zinc oxide arresters, power cables, transformers, circuit breakers, generators, etc. or DC leakage current test. Using AIPWM technology, the inaccurate linearity of PWM technology has been adjusted, so that the accuracy of the instrument has been greatly improved. -

Page 15: Vi.the Use Of Discharge Rod
(4)Test generator VI.The use of discharge rod 1. The special discharge rod should not be in direct contact with high-voltage DC discharge, and should be kept at a distance. When the tip of the discharge rod initially produces corona discharge, and the voltage on the test object gradually drops by 20% of the test voltage, then touch the discharge rod to the shell of the microammeter.
