Abstract
A diagnostic instrument distinguishes primary arcs from other electrical discharges in an electric power system based on pulse time density of radio frequency noise caused by the discharges. The instrument counts a maximum number of noise pulses in any small time window over a period, and identifies the discharges as primary arcs if the pulse time density is in a range characteristics of primary arcs.
