Abstract
A system for detecting a fault type and faulted phase in a power grid includes a controller and a relay. The relay is configured to monitor a line of the power grid and generate a monitoring signal. The controller may be configured to determine, in response to the monitoring signal received from the relay, sequence voltages and sequence currents in the line. The controller may further determine, in response to the sequence voltages and sequence currents, an absence or a presence of a weak-infeed condition in the line. The controller may further determine, in response to the monitoring signal and the absence or the presence of the weak-infeed condition, a first plane sequence signature and a second plane sequence signature. The controller may further determine a fault type and faulted phase in the power grid in response to the first plane sequence signature and the second plane sequence signature.
