ABSTRACT:
A current sensing apparatus suitable for sensing the amount of current flowing in a power feeder cable without the necessity for any ohmic connection between the meter and the circuit being measured that does not require separation of the wires in a cable and in fact utilizes both current carrying wires simultaneously includes a magnetically permeable core suitable for concentrating the magnetic fields generated by the current flowing in the pair of wires and includes a single coil disposed upon the core. The core includes a pair of poles which are placed proximate to the feeder cable and the coil yields an induced output voltage proportionate to the current flowing in the feeder cable and may be held in position on the feeder cable with the aid of a resilient member which permits ready removal of the sensing apparatus.
