Abstract:

A power system that supplies electrical power to at least one load is disclosed. The power system may include an electrical power generator, current sensors configured to provide current signals representative of currents output from the electrical power generator to the load, and voltage sensors configured to provide voltage signals representative of voltages output from the electrical power generator to the load. The power system may also include a controller configured to receive the current signals and the voltage signals, compare the current signals and the voltage signals to a predetermined map, determine whether a short circuit exists inside the electrical power generator based on the comparison, and send a command to turn off the electrical power generator when the short circuit exists inside the electrical power generator.
