working principle:
Shanghai Single-Cup Automatic Insulating Dielectric Strength Tester adopts AC reversible motor pressure regulator to automatically and uniformly boost pressure. When the oil is broken down, the protection system automatically cuts off the circuit. When the breakdown occurs, the discharge spark is small and no free carbon is produced. For six consecutive tests, the dispersion is small and there is no need to stir between the electrodes. The oil cup is placed in a closed glass cover with an interlocking device. Opening the cup cover automatically cuts off the high voltage circuit without storing charges and ensuring personal safety.
