Comment on Millions of smart meters will fail when 2G and 3G turns off
echodot@feddit.uk 8 months agoI work on the national electrical grid and there are a bunch of remote sensors in all of the substations. Some of them are what essentially amount to remotely controlled circuit breakers. I think they trip automatically if they lose connection because they assume something bad has happened. So that’ll be fun.
I work on the software side of things I’m not an electrical engineer so I have no idea if they’re actually changing them over yet but they’re still thousands of them on the network at the moment.

I work for the grid too and we also have these. Usually only for bigger substations to Transmitter measurements and switching states, maybe a bit of telemetry like a tripped fuse.
I hope for dear god that you are remembering wrong and none of them trigger when loosing connection. Whoever thought of that should be immediately fired.
A loss of connection from a single device should never trip a circuit breaker (no idea how the bigger equivalent is called in english), especially if its connected wireless.

The software that controls them is absolutely terrible so I wouldn’t be surprised if that is how they work.
But thinking about it it does seem really stupid for no reason so maybe what it is is the concern that if they do trip after 2G is turned off there’s no way for us to know that.
