ABSTRACT:
A coupler series connects in the power line to be monitored. Sensing circuitry within the coupler senses power flow in each direction of the power line, and produces D.C. signals representing the magnitude thereof. The D.C. signals appear at contacts on the body of the coupler.
A housing is provided with a cavity for receiving the coupler. Contacts in the housing adjoin the cavity and are aligned to connect to the coupler contacts. A D.C. activated meter is mounted in the housing, and is electrically connected through a switch to the housing contacts.
In operation, the coupler is series connected in the line and, when power is to be monitored, it is secured within the housing. By operating the switch, a user may monitor power flow in either direction down the line.
