Loadshedding oddity.

[Rickster]

Quick one, I have this fan in my room that beeps once when you plug it in the wall for power, I also have these battery powered loadshedding bulbs that stay on when the power goes out.

Now, just after loadshedding starts about 1 min later the fan will beep 3 times and the battery powered lights flicker 3 times when the power goes out.

I got curious one day and hooked up a multimeter to a PC power cord and it read 3v every time the fan beeped, so 3v-0v-3v-0v... Sometimes it will do this for longer, no longer than 1 min, also it would sometimes do this 5 min before loadshedding ends.

What would cause this?

Dips and spikes. The reason you want stuff on surge and low voltage protection, preferably something with a 5 min. delay.

Anyways, that's my theory.

Remove the load shedding lightbulb and see if it still behaves the same.

I did, the fan still beeps.

Someone asked this before, I replied with buy more fans to harness the voltage

 

[krieg]

I did, the fan still beeps.

You can't always trust a multimeter's reading, I would test with a resistive test bulb first to verify actual voltage, if you actually have a voltage leak somewhere I would first test if it is in the house or coming from the mains. Might be worth considering a over/under voltage protection device.

I have an oddity.

No loadshedding since they announced stage 6.

 

[AstroTurf]

Some of my lights plugged into ceiling fan fixtures also do strange things.

Like if the fan is on and the power goes off the lights will flash till the fan comes to a complete standstill then you have to turn them off and on again or they keep flashing.

Eskom would like to know your location.

Eskom would like to know your location.

They can check with the FBI like everyone else.

Have you had someone move into your 'hood recently who is fat, black, multiple folds on the back of the neck with a bald head that looks like a malteser in the sun?

It's probably some residual current produced by the fan motor as it spins.

And then

Something strange I noticed during loadshedding.

So I have this fan that beeps when you turn it on via the remote etc. During loadshedding I would hear it faintly beep a couple of times, thinking this was just a capacitor I just ignored it. Today I connected a multimeter in one of the sockets and found that every time it beeps I would get a...

Forgot a made that TBH.
