- •
A strategy based on voltages and currents at all sources is used for fault location.
- •
The 60Hz-measurements and the system parameters are used to define the location.
- •
The strategy examines the entire feeder length to find the faulted node.
- •
A new criterion is used to obtain the location in case of faults at radial feeders.
- •
A unique equation is used for location of shunt-faults in non-radial feeders.
