Current transformer assemblies

摘要

A current transformer assembly has an annular transformer encompassing a busbar where it projects through the wall of equipment. The assembly has an electrically-insulative housing bolted to the equipment wall. The housing has a rear wall with an aperture through which the busbar extends, the transformer being located in a recess between the rear wall of the housing and the front of the equipment wall. The housing is open on its front and has a removable cover plate. The busbar is bolted to the upper surface of a plinth in the housing, which also supports the end of a cable entering through the front wall and bolted to the busbar.
