AC motor capacitor leads to the end of the shell and the voltage test between the provisions of what

September 16, 2020

Capacitors shall be capable of withstanding the sine wave ac voltage test as specified below applied to the terminals (connected together) and the enclosure at a frequency as close as possible to the rated frequency.

Twice the rated voltage + 1000V, but not less than 2000 V. Duration of the test: 60 s during type test and at least 1 s during factory test If the capacitor case is of insulating material, the test voltage shall be applied during the type test (If any) between the terminal and the metal frame, or between the terminal and the metal foil tightly encasing the surface of the case. During the factory test, the test voltage shall be applied between the terminal and the metal part Words).

If the housing is entirely made of insulating material, you do not have to make a factory test.

During the test, there should be no dielectric breakdown or flashover.

The above is the AC motor capacitor leads to the end of the shell and the voltage test between the provisions of what we have listed for you. You can submit the following form to obtain more industry information we provide for you.
