Dielectric withstand test is performed to prevent electric shock and leakage accidents during product use, and to confirm product safety. It is also used to check the function and performance of insulators. For example, CV cables that transport high voltage from generators, wire harnesses and signal cables that transport electrical signals are covered with insulating materials such as plastic and film.
There are two types of insulation tests: insulation resistance tests and voltage resistance tests (dielectric breakdown tests). The insulation resistance test is a test to check if the insulation is properly maintained. The insulation resistance is calculated by applying a certain voltage to the insulated area and measuring the leakage current. A voltage resistance test is a test to check if insulation is not destroyed by applying a high voltage. For each electrical product, the details of the insulation resistance test and the resistance value to be guaranteed are listed.
In order to perform the insulation test, a transformer must be used to create a high voltage. Matsusada Precision has a range of power supply equipment that can be used for insulation resistance testing.
