Self-healing low-voltage shunt capacitor is widely used in network, to check its reliability in network operation, it is very necessary for destruction test.
In order to improve the safe reliability of shunt capacitor devices, some units like to enlarge the reserved capacity, such as increasing the rated voltage of capacitor, when they choose equipment.
