Abstract :
With the wide spread of HV switch cabinet in the electric system, how to effectively monitor the insulation inside the cabinet to avoid the fault is an important subject which all technicians are confronted with. The principle of the TEV measurement and its application in electric system are introduced to demonstrate the effectiveness of this method in the online test of partial discharge in the HV switch cabinet with the real case.
