Abstract
A device for measuring current of an electric power line conductor includes a housing with an opening for accepting a power line conductor. A first coil loop including coil windings with a first end spaced from a second end and having a circular shape. The first coil loop is configured to partially surround the power line conductor located in the housing. An internal central wire attached to an end of the first coil loop extends through a center of the first coil loop. A jaw assembly is configured to insure a vertical centerline of the first coil loop is aligned with a vertical centerline of the electric power line conductor.

A device for measuring current of an electric power line conductor comprising:
- a housing including an opening for accepting a power line conductor;
- a first coil loop including coil windings with a first end spaced from a second end and having a circular shape and configured to partially surround the power line conductor located in the housing and an internal central wire attached to an end of the first coil loop and extending through a center of the first coil loop;
- and
- a jaw assembly configured to insure a vertical centerline of the first coil loop is aligned with a vertical centerline of the electric power line conductor.
A method of determining a fault on a power line conductor comprising the steps of:
- determining a magnitude and a direction of a load current waveform in the power line conductor with a loop coil;
- determining a magnitude and a direction of a fault current waveform in the power line conductor with the loop coil;
- comparing a polarity of the fault current waveform with a polarity of the load current waveform to determine if a change in polarity between the fault current waveform and the load current waveform occurred to determine the direction of the fault;
- and
- transmitting data representing a fault to at least one remote location when a predetermined trigger value is reached.
