Got me thinking about the hammering that the switch gear in the substations must take with all the switching off and then back on under load.

Maybe someone in the know can comment on whether the switch gear in substations is actually designed to switch their respective loads as frequently as they do with load shedding. One would think that they were designed to trip under fault conditions and maybe to be switched off for maintenance to be done on the line periodically but I cannot see them lasting too long, being switched off and on twice daily for who knows how long.

"spring loaded"

Just like various types of contactors ...i am sure the fellas who installed the whole load shedding system would have taken all this into consideration... like they did with the new power stations.

I am hoping the load shedding continues over the next few weeks... i will have the fluke 435 connected to an 800 amp supply in a factory... it is going to be interesting to see the voltage "spikes" as they are referred to... in the past 2 years i have seen more damaging "dips" in power than surges

I have seen a few voltage surges due to neutral conductor theft.
