Abstract
According to an embodiment of the present invention, an apparatus for determining the location of an electrical disturbance in a circuit is provided. The apparatus has at least one sensor configured to determine the relative phase of current and voltage waveforms across the circuit inductance of a portion of the circuit produced by a voltage or current perturbation, and a controller configured to identify the location of the electrical disturbance within the circuit from the relative phase of the current and voltage waveforms.

An apparatus for determining the location of an electrical disturbance in a circuit, the apparatus comprising:
- at least one sensor configured to determine the relative phase of current and voltage waveforms across the circuit inductance of a portion of the circuit produced by a voltage or current perturbation;
- and
- a controller configured to identify the location of the electrical disturbance within the circuit from the relative phase of the current and voltage waveforms.
A circuit comprising:
- a power source;
- at least one distribution leg comprising a load;
- and
- at least one apparatus for determining the location of an electrical disturbance in a circuit, the apparatus comprising:
- at least one sensor configured to determine the relative phase of current and voltage waveforms across the circuit inductance of a portion of the circuit produced by a voltage or current perturbation;
- and
- a controller configured to identify the location of the electrical disturbance within the circuit from the relative phase of the current and voltage waveforms,
- wherein the apparatus is configured to identify the location of an electrical disturbance within the power source portion or the at least one distribution leg.
A method for determining the location of an electrical disturbance in a circuit, the method comprising:
- determining the relative phase of current and voltage waveforms across the circuit inductance of a portion of the circuit produced by a voltage or current perturbation in the circuit;
