ABSTRACT:
Apparatus 50 for the detection and location of arcing within an enclosed electrical device, such as an electric generator 20. Fiber optic cables 53 are strategically mounted within the generator 20 detect emitted light 44 incident to arcing of the stator windings 32. Positive indication is given that the source of the arcing is within the generator 20 itself. By examining and comparing the relative magnitude and intensity of the light 44 received by each of the individual fiber optic cables 53, the location of arcing within the generator 20 can be established.
