Hi Doctor
Would you let us know how to test dirty electricity of water pipe or window frame by oscilloscope ?
I am wondering if thet are polluted by dirty electricity
Thank you very much
An easier approach is to test for stray voltage AC. If there are stray voltages, then there is likely dirty electricity too. If the voltage is zero or near zero, then you should be okay.
Use a voltmeter that can measure at least 600 mV AC. Ground the meter to the Earth, set on V AC, and probe the metal pipe and window.
