Dielectric withstand voltage for NTC thermistors assures that no dielectric breakdown will occur when an extremely high voltage is applied to the thermistor. In the case of the NTCRP series, this is ascertained by applying a high voltage to both the thermistor and the conductive material surrounding it, and confirming the absence of leakage current.
Insulation withstand refers to the voltage tolerated by equipment insulation without failure. Knowing the withstand capability and endurance qualities of the insulation system is vital. Insulation-type designations, as well as high-potential and surge-voltage tests, classify the insulation''s properties and state the withstand capabilities.
Dielectric withstand test. In electrical engineering, a dielectric withstand test (or pressure test, high potential or hipot test) is an electrical safety test performed on a component or product to determine the effectiveness of its insulation. The test may be between mutually insulated sections of a part, or energized parts and ground.
