Abstract

A transformer truck for a transformer system is provided. The transformer truck defines a first direction, a second direction, and a third direction, the three directions orthogonal to each other. The transformer truck includes a housing and a grounding switch mechanism. The housing is arranged to receive a first transformer, the first transformer in a first orientation relative to the third direction and a laterally adjacent second transformer in a second orientation relative to the third direction, wherein the second orientation is opposite to the first orientation. The grounding switch mechanism is coupled to the housing, is switchable between a non-grounded condition and a grounded condition, and includes a pair of grounding arms each coupled to respective inner portions of the housing and rotatable between the non-grounded condition and the grounded condition and a grounding bar extending between the pair of grounding arms.
