Claim Text:
1. A method of determining a fault on a power line conductor comprising the steps of: mounting a sensor transmitter receiver unit on the power line conductor with a jaw assembly, wherein a first end of a loop coil is rigidly fixed from movement relative to a second end of the loop coil when the jaw assembly moves between an open position for accepting the power line conductor and a closed position for engaging the power line conductor; determining a magnitude and a direction of a load current waveform in the power line conductor with the 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.
