ABSTRACT:
The present invention monitors RF emissions within a turbine generator. A coupling device provides a connection between preexisting thermal sensor leads and an RF monitor. Preexisting thermal sensor leads are connected to thermocouples and resistance temperature detectors during manufacture of the turbine generator. The RF monitor is used in the present invention to monitor RF emissions flowing in the thermal sensor leads thereby avoiding a need to retrofit RF sensors on the generator. The present invention also provides a capacitive coupling means between the thermal sensor leads and the RF monitor. The present invention also provides an inductive means to reduce interference from RF emissions having sources external to the generator.
