How To Test The Reaction Torque Of High Voltage Disconnector

First, remove the high voltage isolator mechanism and retain the high voltage isolator switch connection mechanism. Use a digital torque wrench to test the torque on the hv isolator transmission spindle. At this time, the main test is the reaction torque of hv isolator switch (the friction torque of the high voltage electrical isolator connection mechanism is relatively small under this condition).
