GGuineafowl replied to the thread When 50,000 volts go through a wire at 5,000,000 FPS - The Slow Mo Guy.What I said seemed to be the conclusion of Veritasium’s experiment? Time to first current pulse in the bulb was 1m/c seconds, determined...

GGuineafowl replied to the thread When 50,000 volts go through a wire at 5,000,000 FPS - The Slow Mo Guy.A ‘negative’ wavefront? Does an opposite wavefront travel the other way around the circuit? I did see those, and the responses from...

Yes, that works for me. But the charges inside the wire (the waveguide part) are also involved. Ultimately it's a bit too complex to be... -

One of these terminals has an excess of electrons on it, waiting to "go". That is the initiation of the wavefront. We require electrons...

GGuineafowl replied to the thread When 50,000 volts go through a wire at 5,000,000 FPS - The Slow Mo Guy.Could it be said that the connecting wires have some velocity factor, eg 0.7, and the electric (electromagnetic?) wavefront travels at...

I had an interesting chat with a guy in UK Power Networks. He saw my problem. He did say that the supply may never have been changed... -
GGuineafowl replied to the thread Following up on the recent thread about Earth Resistance measurements.The PV installers wouldn’t have seen a problem - 130Ω is within spec for TT. Don’t forget the RCD requirement. I can’t explain why...

GGuineafowl replied to the thread Following up on the recent thread about Earth Resistance measurements.Unlikely. - Service head belongs to your DNO. - Meter belongs to your energy company. - Anything after that belongs to you, and you or...

GGuineafowl replied to the thread Following up on the recent thread about Earth Resistance measurements.I’m not sure what you mean by this - in the common TN-C-S system they are linked. Unless you mean YOU are forbidden from doing it, which...

GGuineafowl replied to the thread Following up on the recent thread about Earth Resistance measurements.Ok. It’s hard without being there or seeing pictures, that’s all. Does it dive into the wall, where do you lose sight of it? In any...

GGuineafowl replied to the thread Following up on the recent thread about Earth Resistance measurements.I’d have to add (see post #11) that this is not the case for TT and TN-S installations.

GGuineafowl replied to the thread Following up on the recent thread about Earth Resistance measurements.One further thought, @sophiecentaur , is that your PV installation should have involved some basic electrical tests on the existing...

Ok. Makes sense. So line and neutral do not float.
