Abstract
Disclosed are various embodiments for fault location in an active compensation resonant grounded power distribution system. In one embodiment, an inverter is programmed to allow a configurable set of triplen harmonics to pass during the ground fault condition for a duration of time. First current sensor data from a first line sensor mounted on a line conductor is analyzed to determine that a programmable set of harmonic currents are present. Second current sensor data from a second line sensor mounted on the line conductor is analyzed to determine that the programmable set of harmonic currents are absent. The second line sensor is downstream of the first line sensor on the line conductor. A ground fault being compensated for by the active compensation resonant grounded power distribution system is determined to be present on the line conductor between the first line sensor and the second line sensor.
