Abstract
Traditional voltage withstand equipment can only tests withstand voltage under 2 kV,class Ⅱ insulation energy meter can not be test.To solve this problem,a kind of new testing equipment was designed.Voltage output above 4 kV is added on the energy meter for one setting time.Then capability of voltage withstand is confirmed by testing the peak current.All energy meter positions are independent.It can switch between the test of voltage withstand and others by separate relay,and change for data by RS485 to control center.It is characterized with easy operation,safety and steady performance.
