Abstract

A switchgear includes a housing having a wall separating a circuit breaker compartment from a bus/cable compartment. A plurality of bushings is provided. Each bushing has first and second portions. Each bushing extends through the wall so that the first portion is disposed in the circuit breaker compartment and the second portion is disposed in the bus/cable compartment. Each second portion has an extension. At least one current transformer is mounted on the extension of the second portion of each bushing. The extensions are constructed and arranged so that a phase to phase distance is 180 mm or less. Such a configuration also decreased the overall size of the switchgear.
