What is stand voltage testing?
Withstand voltage testing is used to check whether a given electrical product or part provides sufficient dielectric strength (i.e., insulation strength) for the voltages to which it may be exposed. Three locations are tested: 1.
Why are withstand voltage tests important?
Why are withstand voltage tests important and what are the test methods? Withstand voltage testing is used to check whether a given electrical product or part provides sufficient dielectric strength (i.e., insulation strength) for the voltages to which it may be exposed.
What is a withstand voltage test / partial discharge test?
Withstand Voltage Test / Partial Discharge Test – KIKUSUI ELECTRONICS CORP. What Is a Withstand Voltage Test? The withstand voltage test also called the dielectric strength test or hi-pot test, is a test to evaluate whether the insulation of electrical products and parts has sufficient dielectric strength against the voltage.
What is withstand voltage?
A very high voltage (up to the range at which dielectric breakdown is likely to occur) is applied to determine the withstand voltage. The voltage is gradually increased and the point at which dielectric breakdown occurs is called the withstand voltage (limit voltage). The Purpose of Withstand Voltage Tests
What is the purpose of voltage resistance testing?
The purpose of voltage resistance testing is to verify whether electrical products have sufficient dielectric strength to protect consumers and their property from electric shock, fire, and other hazards. The figure on the left illustrates the withstand voltage test.
What is a withstand voltage tester?
Z1 and Z2 between the AC line and the chassis contain Y capacitors, which have the characteristics of passing AC and are mainly used for noise removal. The withstand voltage tester detects the overall leakage current, including the current flowing through the capacitors, and checks whether it exceeds the set limit value.
