Hi guys,
I have a setup in which 1000v 50Hz sinusoidal waveform have information signal of 1kHz riding on the 50Hz sinewave. volatge level of this 1KHz signal is 8volts AC.
can anybody help me to design a circuit to detect the 1kHz signal from 1kV line?
If I use a potential divider circuit to take 10 v of 50Hz signal then 1Khz signal level will also drop with same proportion... there should be an isolation circuit, between high voltage and signal detector electronic circuitry.
What cooments from you will be highly appreciated.
Kind regards,
Fraz
