With a total of 3 patents to his name, Perulfi has developed innovative solutions that enhance the efficiency and reliability of electrical systems.

Latest Patents

One of Perulfi's latest patents is for a multiple vacuum interrupter fluid insulated circuit breaker. This circuit breaker utilizes a plurality of vacuum interrupters immersed in oil. A cross-bar with electrically conductive sections completes a series electrical circuit through the circuit breaker and actuates operating mechanisms. When in the raised position, the cross-bar closes the contacts of the vacuum interrupters. As the cross-bar is lowered, the contacts of the vacuum interrupters are opened by impact forces before isolation gaps, which fill with oil, are created in the series electrical circuit. Various arrangements of the vacuum interrupters are disclosed for uprating existing oil circuit breakers.

Another significant patent is for a current transformer characterized by a terminal bushing extending from a tank. This transformer features a pair of spaced conductors extending through the bushing and into the tank, with the portions of the conductors in the tank being enclosed within tubular means. The assembly of the conductors, bushing, and tubular means is clamped together by resilient (spring) means for holding the conductors in tension and the bushing and tubular means in compression. The transformer also embodies two separate oil systems.
