| Sep 6 at 8:14 | comment | added | DreiDe | I was thinking about 230V AC mains. With higher single phase voltages I wouldn't be able to plug in the scope to the same isolation transformer as the DUT. I see that because of filter caps/noise in gerneral it could make the measurement inaccurate but does this make user safety any worse? | |

| Sep 6 at 4:39 | comment | added | Justme | What kind of HV measurements you are talking about? If the HV is earth referenced without the isolation transformer, if it is too high, you need the correct probes anyway to measure it. Isolating it would change nothing. Can you be more specific about the scenario you are after? Or does HV means "unisolated rectified mains at most" to you? Because, floating a scope, or desktop computer, or any other three pronged device makes no sense because they have mains inlet filter caps to the earth you just disconnected with the isolation transformer. | |
