Abstract: A support bracket assembly for supporting a pair of bushing well interrupter devices provided within a transformer enclosure that encloses a transformer. The support bracket assembly includes a mounting bracket assembly rigidly secured to a parking stand on the enclosure and including a plurality of mounting bosses. The support bracket assembly further includes support brackets, a first adjustable link secured to one of the mounting bosses on the mounting assembly and a mounting boss on a support bracket, a second adjustable link secured to another one of the mounting bosses on the mounting assembly and a mounting bosses on a support bracket, and a third adjustable link secured to mounting bosses on two support bracket, where the first, second and third adjustable links form a triangular configuration.

Abstract: A system and method for determining an open or closed position of a magnetically actuated vacuum interrupter. The method includes applying a voltage signal of a known voltage to the actuator over a predetermined period and determining a change in current over time during the period when the voltage signal is applied to the actuator using an output of a Rogowski coil. The method also includes calculating the inductance using the voltage and the change in current over time at a predetermined time during the period and using the calculated inductance to determine whether the actuator and thus the vacuum interrupter are in the open or closed position.

Abstract: A circuit breaker system uses a microprocessor for calculating at least one function of a measured current flow.

Abstract: A circuit breaker system employs a sensor circuit to measure the current flow in a conductor. A microcomputer monitors the current flow and trips a circuit breaker if the measured current flow exhibits certain predetermined characteristics. A power supply circuit generates a regulated output voltage proportional to the measured current flow to supply power to a portion of the circuit breaker system electronics. To protect the portion of the electronics powered by the power supply circuit, the output from the power supply is shorted through a resistance circuit for a predetermined period of time if the magnitude of the measured current flow induces an output voltage in excess of a predetermined level.
