We provide High Voltage Transformers for Testing for the need for checking the adequacy of Insulation, provided in the electrical apparatus, cannot be over emphasized. Insulation between the live and earth or between two different sections of live parts, this insulation is required to be tested at high voltage values recommend by applicable relevant standards. The standard specifications for various electrical apparatus specifies power frequency voltage withstand tests at different levels depending upon the working voltage of electrical apparatus. It is observed from the various standard for electrical equipments that the minimum power frequency voltage withstand test level for electrical Insulation is 2KV for one minute.
