How to build Non-contact DC Voltage detector/sensor?
SEM, that's pretty much it.AndreyG said:How to build Non-contact DC Voltage detector/sensor?

Yes, sorry if it wasn't obvious.davenn said:SEM ? (only thing I could put to that was scanning electron microscope ??)
Well then you should have posted that. And you need to post about your thoughts to avoid getting an infraction for being obnoxious...AndreyG said:Dear Berkeman, you over-simplifying it. At least one more method I know myself - field mills.
If you know of a solution, and are asking for additional solutions, post what you know. Please do not waste our time here. We do not appreciate that. We enjoy helping people, but do not appreciate lazy people wasting our time.AndreyG said:Dear berkeman I found your replies confusing sorry. I did not mean to be obnoxious or anything personal. I am new here, asked plain question, got pointless disrespectful sarcasm from you. It does not help.
Have good day.
Baluncore said:You can measure the local voltage gradient by moving a FET gate connection backwards and forwards along a line towards the unknown voltage.
Yes. But we do not know the magnitude of the voltage or the energy involved. That may destroy a FET. It would take exceptionally low leakage diodes to protect the gate.AndreyG said:Do you mean to move it mechanically?

Good thinking young man. Sensitivity and calibration should be soluble.anorlunda said:Yes DC. Put a DC charged wire near the bulb and see distortions is the patterns.
AndreyG said:. Idea of using FET with spatial modulation as suggested by baluncore is scheduled for tests.
