Abstract: A system for detecting electrical arcing on an electrical power system includes: a) a data acquisition unit that is electrically connected to an electrical power system, wherein the data acquisition unit is configured to monitor signals indicative of a first periodic property of the electrical power system, wherein the signal includes a normal load component; and b) a computing device operably connected to the data acquisition unit. The computing device is programmed to: i) obtain first data from the data acquisition unit indicative of the temporal behavior of the first signal; ii) remove the normal load component from the first data; and iii) determine that an arcing event is present on the electrical power system when the at least one burst within the first data presents a generally sinusoidal shape which includes generally flat regions which are present where the generally sinusoidal shape crosses over a zero-magnitude line.

Abstract: A method for analyzing an electrical power system includes analyzing data representing a signal of interest of the power system, the data containing at least one power system event; and based on the analysis, associating the power system event with a root cause. A computer program product is also provided for carrying out the method.
