PORTABLE SELF POWERED LINE MOUNTABLE ELECTRIC POWER LINE CURRENT MONITORING TRANSMITTING AND RECEIVING SYSTEM

摘要

A method of determining a fault on a power line conductor includes the steps of determining a magnitude and a direction of a load current waveform in the power line conductor with a loop coil and determining a magnitude and a direction of a fault current waveform in the power line conductor with the loop coil. A polarity of the fault current waveform is compared 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. Data representing a fault to at least one remote location is transmitted when a predetermined trigger value is reached.
