CPC G01R 31/1272 (2013.01) [G01R 31/40 (2013.01); H03F 1/0233 (2013.01); H03F 3/245 (2013.01); H03F 2200/105 (2013.01); H03F 2200/451 (2013.01)] | 15 Claims |
1. A failure detection system for an energy network, the failure detection system comprising
a radio frequency (RF) receiver adapted to be coupled with or in close proximity to the energy network, the RF receiver providing an amplitude modulated RF signal;
an RF amplifier receiving the amplitude modulated RF signal and providing an amplified signal;
an envelope detector receiving the amplitude modulated RF signal and providing a demodulated envelope signal;
an optional algorithm implementation system receiving the demodulated envelope signal, where the optional algorithm implementation system processes the demodulated envelope signal by one or more of a Fast Fourier transform (FFT) trigger system and a phase-locked loop (PLL) trigger system; and
a signature output that is the overall output signal of the failure detection system, wherein the signature output is adapted to indicate whether the energy network is experiencing partial discharge.
