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.
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. discharge. Finally, hang the ground wire of the grounding end of the discharge rod directly on the test object.
2. Special attention is not allowed to directly discharge the ground wire on the shell of the high-voltage microammeter, so as to avoid the damage of the high-voltage microammeter caused by the strong impulse discharge current.
