ABSTRACT:
A method and system for detecting radio frequency emissions in an electrical machine, by: sensing the radio frequency emissions and deriving a light signal modulated by the radio frequency emissions; conducting the light signal via an optical conductor to a location remote from the site of the emissions; and converting the light signal from the optical conductor into an electrical signal representative of the modulation of the light signal by the emissions.
