ABSTRACT:
A power measuring system includes a transformer that produces a voltage signal in response to the presence of a changing current within a power cable. An input circuit is electrically connected to the transformer for receiving the voltage signal, and produces an analog current signal representative of the changing current within the power cable, in response to receiving the voltage signal. A transmission line has a first end electrically interconnected with the input circuit so as to receive the analog current signal and has a second end electrically interconnected with an output circuit located at a location remote from the first end. The output circuit receives the analog current signal and produces a resultant signal in response to receiving the analog current signal. The resultant signal may be used to provide a meter display. A housing for a sensing transformer having a split toroidal core is disclosed.
