I think I have it for an early warning of imminient load shedding

As you are aware I'm doing research on the ripple control systems used in JHB I am working on decoding the data sent and what I have found is that today, some very peculiar data being sent, where basically everything is being turned off across the board. I have of course seen this before and when I did see it last time, I happened to be working on the project and the power went out very shortly thereafter.

I saw a similar transmission this morning so, I am now idling here and waiting to see what the exact sequence is before the power is cut, I believe it will be cut at 10:00 which is exactly 2 hours away so let's see if it works out.

The benefits of this is huge, we'd be able to switch a generator in without power dipping or interrupting the supply to sensitive stuff like computers and CNC machinery. No UPS needed in other words.
