| Abstract: | In the process of field application,poor insulation resistance exists in the indication part of switch locking devices,including VCC and VPM.Through replacing contact materials or conducting insulation processing of materials for the existing contacts,two solutions to improve the insulation of the system were proposed by analyzing the data from a 12 cycle alternating hot and humid experiment. |
