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.
The withstand voltage testing equipment is an important electronic testing equipment, which is mainly composed of AC (DC) high voltage power supply, timer controller, test circuit, display circuit and alarm circuit, etc.
In addition, the dielectric voltage withstand test may reveal faults in mechanically damaged insulation or the presence of a foreign material (such as water) which may bridge the insulation. This test is often used after mechanical abuse or temperature tests to confirm that the product has maintained its insulating capabilities.
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.
Withstand voltage testers must be able to apply the test voltages described in the standard and to measure the breaking current. They are also subject to requirements such as the following as imposed by standards and laws: • The voltmeter precision must be JIS Class 1.5 or greater.
It is performed in AC or DC with voltages varying from some hundred volts to several tens of kilovolts. The choice of the nature and value of the test voltage is determined by standards which apply to the product tested.
