What Are The Effects Of Moisture On A High-voltage Disconnecting Switch?

Malfunction of isolator high voltage may also be due to moisture. A damp environment causes the internal electrical contacts of high voltage isolator to be corroded by moisture, increasing contact resistance and causing poor signal transmission, which in turn affects the normal operation of high voltage isolator switch. Moisture can also degrade the performance of insulation materials, increasing the risk of failure. In severe cases, it may cause hv isolator to fail to open and close normally, or even cause safety hazards such as short circuits.
