VEER make High Voltage Tester VHT is specially designed to test Dielectric Strength of Device under Test as per applicable standards. High Voltage test is required to determine whether test object has proper insulation or not. High Voltage test is carried out as Routine Test Each device is subjected to test at high voltage of 1 kV + 2 x (working Voltage)If Insulation is weak then device will consume more power because of leakage current which causes more heat. Heat will reduce the reliability and overall life of device under test It is also responsible for high risk of electric shock. So, High voltage test is necessary for all electrical equipments.

High Voltage terminal of EIV Tester is connected to the conductive part (Device under Test) and Earth Terminal Should be connected to safety ground (Earth ground). If the insulation between the two adequate, then the application of a large voltage difference between the two conductors separated by the insulator would result in the flow of a very small current Although this small current is acceptable, no breakdown of either the air insulation or the solid insulation should take place. If device under test draws more than pre set value current then tripping will occur and test will get off. In this way we can find problem in the insulation of device under test.
