Description
Overview
GAOTek partial discharge tester the fault types of switch cabinet can be generally divided into refuse operation or mal operation fault, insulation fault, breaking and closing fault, current carrying fault, external force fault and other faults. Rdpda-102 partial discharge inspection instrument adopts two new technologies transient voltage to ground (TEV) measurement and ultrasonic (US) measurement to detect the fault of switchgear. The equipment is portable and easy to operate. The TEV sensor is attached to the wall of the box, and the US sensor scans along the gap on the switch cabinet. There is no damage to the high-voltage switch and switch cabinet, and all the tests have no impact on the operation of the high-voltage switch and switch cabinet equipment. This can observe the measured signal in multiple periods, identify the discharge frequency, and analyze various modes to clearly judge whether the switch cabinet is faulty. Its measurement technology has reached the leading level at home and abroad.
