MissInformationsomething, something energy conductor
C++ Wage SlaveI wonder why the system can leak so much current to earth and still not cut out.
I also wonder about the voltage on those transmission lines, right outside people's houses.

Because the system carries thousands of amps under normal conditions. This isn't enough to register as a fault.

jan guerillahandwerker ullrich@brouhaha @CppGuy @MissInformation typically you find a ground fault detection independent from amps and current monitoring

I haven't seen that in neighborhood distribution, but I'm not a power distribution engineer. Even so, the fault current to trip it would have to be quite high.

I guess you don't want a domestic wiring problem taking out the power for the whole neighborhood. But this is not that. 😄
@brouhaha @CppGuy @MissInformation not sure about the oversea way of doing electricity, but that's a common thing in europe.
John Francis 🦫🇨🇦🍁💪⬆️@brouhaha @young_ullrich @CppGuy @MissInformation distribution circuits don't have any neutral line returning upstream. The neutral in a household circuit is bonded to ground in the panel. Ground fault detection is between live & neutral. Distribution is to ground via load. The molten ladder is an acceptable load.
@brouhaha @young_ullrich @CppGuy @MissInformation if the ladder gets a top high voltage wire, its also beyond the fuse coming out of the service transformer.
I wonder if the auditors will notice they didn't seem to get paid enough for that neighbourhood distribution circuit.
I'm unsure of some of the terminology here (especially panel) but, here in the UK, we do get an earth line from the 230V transformer to the house. I know more about that than I want to because of fun and games getting an adequate supply to our new heat pumps.
I have no idea on what goes into that transformer, so, if you're saying that an 11kV supply has no earth then I'm not arguing.
@CppGuy @brouhaha @young_ullrich @MissInformation we also get an earth from the circuit breaker panel in the house to the nearest transformer, but it doesn't go back any further. My nearest transformer is fed by a single high-voltage wire, something around 3-6 KV. That's the ladder liquifier, it live right at the very top of the poles. To keep the local bumbling telco contractors from touching it.
@johnefrancis @CppGuy @brouhaha @young_ullrich As a person from a country where the energy network is largely buried in the ground, I am always amazed at the structure of energy networks in other countries. 😁
@MissInformation @CppGuy @brouhaha @young_ullrich some is buried here, in new construction, dense urban environments. But overall it's tough to beat just hanging the wires on specially prepared trees for cheap.

Anyway, the ladder will eventually melt down enough to fall away from the transmission line and the problem will correct itself.
