ABSTRACT:
The phase of electrical current flowing through a power distribution network is sensed and fed to a computer. A transducer also detects the position and movement of an insulator rod used to mechanically open the contacts of a high voltage circuit breaker in the power distribution network. Signals indicative of insulator rod position and movement are also furnished to the computer. When it becomes necessary to open the circuit breaker contacts, the insulator rod movement and the electrical current phase are coordinated so that the contacts are carrying little, if any, current when they open. The fault-interrupting capacity of a circuit breaker is increased, while damage to the breaker contacts is reduced.
