Abstract
Systems and methods for calculating load direction even under adverse environmental conditions are provided. A system may include sensing circuitry and processing circuitry. The sensing circuitry may sense a first parameter and a second parameter of the electrical waveform on the transmission line of the electric power distribution system. The processing circuitry may determine a present load direction of an electrical waveform using a first method based at least in part on the first parameter in response to detecting that the sensing circuitry is experiencing a first environmental condition. The processing circuitry may determine the present load direction of the electrical waveform using a second method based at least in part on the second parameter and not the first parameter in response to detecting that the sensing circuitry is experiencing a second environmental condition.
