Power receiving/distributing equipment is composed of a switchgear incorporated for each major electric path section, wherein, when arc fault occurs on an electric path to which a circuit breaker is connected, a high-speed closing device closes to detour arc current so as to flow to a ground conductor, thereby eliminating arc at a fault electric path portion. The high-speed closing device is connected to one pole or both poles of a breaking portion of the circuit breaker, and is incorporated into an insulating support member on a corresponding pole electric path so as to be able to be drawn as a whole.

A switchgear current transformer replacement system includes a truck system having a connection section. The truck system engages with and moves along a rail system of a compartment of a switchgear. The connection section connects to a current transformer. The truck system is positioned along the rail system to a position adjacent to the current transformer so the connection section connects to the current transformer and moves it away from its operational location within the compartment of the switchgear.
