Stage 2 loadshedding from today until... 11pm Monday

[Grouter]

Really?

Well, every time I look at my little meter, it says "50Hz" - never varies . With my genny running the house, it's all over the place, anywhere from 47 to 55. One of the main reasons I've given up using the genny. That and my inverter, gas hot water and gas cooker.

To be fair, those graphs you cite are pretty steady (apart from that one spike: I wonder what happened there?)

A pc power supply is actually an ac to dc inverter.

I get that but what happens when the DC goes through all the circuitry that was supposed to rectify the voltage?

Can I just connect 230V dc to a phone charger? I am in awe of your bravery, I have a very healthy respect for direct current.

Eksdom is far more destructive!

Wouldn't say steady, just consistently random.

Yes, I also wonder about the high frequency shift to a remarkably consistent 51.9Hz, accompanied by 4.4 VAC, wouldn't call it a "spike", lasted for over 25 minutes...

**** knows! - too scientific for me! Anyways - it's beer time!

CoCT is at stage 1 loadshedding until 18:00... but what's gonna happen after that? Stage 2 or will it be suspended?

Now Stage 1 until 10pm, then Stage 2 until 6am.

 

[RonSwanson]

So here is my graph of yesterday's loadshedding (12H00 - 16H30 slot, ended up being 12H19 to 16H31). Before and after load shedding, grid frequency is a lottery. When load shedding happens, the grid frequency shoots to a very consistent 51.9 Hz, and still delivers 4.8 to 5.2 VAC. I guess that Eskom is quite correct when they say that we must treat all circuits as if they are live (apart from it being common sense).

Now Stage 1 until 10pm, then Stage 2 until 6am.

I saw that. It's good for me since I miss another Loadshedding session, but the frequent short notice changes are a little annoying.

Viva! Such a good story to tell. Wow, ANC, you really are doing us proud

Well there is still a few more penny's to grab... so disappointing they won't even leave you the bread crumbs lol

Freaking round 2 done, tried to sleep but the heat was intense. Neighbours had their genies going, I thought nah I can ride this one out with my phone charged and watch a couple vids.

still delivers 4.8 to 5.2 VAC.

mmm, going to test and see how much VA I get, if any.
Will play around with some components and see if I can charge a phone..
Come to think of it, I can do a lot with 3.3-5V DC

I wish they'd ban generators in residential areas. Flipping irritating.

Strange experience waking just before 6am on a Saturday, knowing that power is going to be off for 2 hours. May as well stay in bed, its lockdown after all...

No better time for a stroll on the beach.

If the generator is too loud turn the volume up on your tv

Can also make a lot of magic blue smoke when it gets back up to 220VAC. Need an overvoltage detection circuit as a first precaution.

Came out of our first load shedding round this morning, recharging batteries getting ready for round 2 this evening
