A dielectric withstand test is performed to confirm a product's safety by preventing electric shock and current leakage during its use. It is also used to verify the function and performance of insulators. For example, components like CV cables that carry high voltage from generators, as well as wire harnesses and signal cables that transmit electrical signals, are all covered with insulating materials such as plastic and film.
There are two main types of insulation tests: the insulation resistance test and the dielectric withstand test. The insulation resistance test measures the resistance of the insulation by applying a specific DC voltage and measuring the resulting leakage current, verifying that the insulation is adequate. In contrast, a dielectric withstand test (also known as a hipot test) verifies that the insulation is not damaged when a much higher voltage is applied for a short period. For every electrical product, the specific test parameters and required values are defined in its corresponding safety standards and specifications.
Performing these tests requires a high voltage power supply to generate the necessary test voltages. Matsusada Precision offers a wide range of high voltage power supplies suitable for both dielectric withstand testing and insulation resistance testing.
