Abstract
A system for identifying an arcing event in electrical distribution systems is provided. The system comprises a sensor configured to detect ultraviolet light and to generate a signal indicative of the arcing event propagating from the electrical distribution system. A processor coupled to the sensor and configured to analyze an ultraviolet light characteristic from the signal and generate an arc fault signal. A protective device configured to receive the arc fault signal and to mitigate the arcing event in the electrical distribution system.

A system for identifying an arcing event in electrical distribution system comprising:
- a sensor configured to detect ultraviolet light and to generate a signal indicative of the arcing event propagating from the electrical distribution system;
- a processor coupled to the sensor and configured to analyze an ultraviolet light characteristic from the signal and to generate an arc fault signal indicative of the arcing event;
- and
- a protective device configured to receive the arc fault signal and to mitigate the arcing event in the electrical distribution system.
An arc detection system for identifying an arcing event within an electrical distribution system comprising:
- a plurality of optical sensors disposed proximate to the electrical distribution system and configured to sense an ultraviolet light and to generate a first signal indicative of the arcing event in the electrical distribution system;
- a plurality of radio frequency sensors disposed proximate to the electrical distribution system and configured to sense a radio frequency signal indicative of the arcing event generated in the electrical distribution system;
- a processor coupled to the optical sensors and to the radio frequency sensors, the processor being configured to extract an ultraviolet light characteristic from first signal, and a radio frequency characteristic from the radio frequency signal, and to compare the extracted ultraviolet light characteristic and the extracted radio frequency characteristic to a pre-determined characteristic to identify occurrence of the arcing event, and to generate an arc fault signal;
- and
- a protective device configured to receive the arc fault signal and to mitigate the arcing event in the electrical distribution system.
