High Voltage Test Sets

Every electrical apparaus or machine is provided with insulation between live part and earth or between two or between two different sections of live parts. This insulation is required to be tested at high voltage values recommended by applicable relevant standards.              The standard specification for various electrical apparatus specifies power frequency voltage withstand test at different levels depending upon working voltage of electrical apparatus. It is observed from the various standards for electrical equipments that the minimum power frequency voltage withstand test levelfor electrical insulation is 2 KV for one minute.
