Two-stage high impedance fault detection

Abstract

A method and apparatus detect and localize of electric faults in electrical power grids and circuit. Readouts from remote sensors are pre-analyzed by remote processor units using pre-defined updateable fast algorithms to make an initial identification of a high impedance electrical fault. Whenever the data is remotely qualified as potentially representing a fault, it is then transmitted to the central processor unit running sophisticated, potentially self-learning, easily modifiable and adaptable algorithms for detailed analysis of the transmitted signal. The central process can request more data from other remote processor units than the one or more remote processor units reporting the potential fault for comparative analysis. The remote processors are provided with limited storage capacity to allow backtracking readouts for a limited period of time.
