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 housing for a hermetically sealed bulkhead connector is machined of an integral metal member to have a precisely planar bulkhead-engaging surface of a mounting section extending peripherally around a contact support section disposed within a hood section extending through a cutout of the bulkhead. The housing also is machined to have precisely planar surfaces of a contact support section to facilitate assembly of contacts precisely concentrically disposed in passageways through the support section and securing therein by glass seals to comprise a parallel contact array. The housing is free of joints between the several sections which could provide sites for breaching the hermetic nature of the housing. No steps are performed which involve impacting or striking the housing which could disturb the precise planarity of the several precisely machined surfaces. The contact positions may be identified by laser etched indicia.
