Question about loadshedding

[markanthony61]

Hi all,
Just a question out of idle curiosity, how exactly do they go about implementing loadshedding? By that I mean, how do they acually switch off the power? Is there one big breaker switch for each area or are there multiple switches that need to be thrown to turn power off?

And how commonly are the breakers remotely actuated from a control room?

They are actuated remotely. Problems arise when substations are faulty and staff have to go manually operate the transmission system.

The way I understand, it's not one big breaker, but multiple breakers at various substations actuate remotely at the same time to switch off a large area.

@Bliksis, thank you for your reply, I think I understand, who actually does this the local municipality, like for instance in my case City of Cape Town, or Eskom themselves?

The local municipality usually does this although in the case of Cape Town you have Eskom supplied areas and city supplied areas. The Eskom supply area load shedding is managed by Eskom and don't benefit from Steenbras.

City of Cape Town control their own network. I *think* Eskom says hey, cut xxx amount, and City decides which areas for how long.

I might be wrong, so I'm open to be corrected.
