Abstract
An electric arc detection system is presented. The electric arc detection system comprises a receiving antenna that receives electromagnetic radiation generated by an electric arc formed in an internal cavity of a non-conductive hollow structure, and a processing subsystem for determining an existence of the electric arc in the internal cavity based upon signals representative of the electromagnetic radiation.

An electric arc detection system, the system comprising:
- a receiving antenna that receives electromagnetic radiation generated by an electric arc formed in an internal cavity of a non-conductive hollow structure;
- and
- a processing subsystem for determining an existence of the electric arc in the internal cavity based upon signals representative of the electromagnetic radiation,
- wherein the receiving antenna comprises a directional antenna directed towards at least one potential electric arc location in the non-conductive hollow structure.
