My landed type house using single phase system
All the lamps will flicker suddenly. Sometimes very frequent sometimes not at all
Today suddenly the lamp and fan became very bright and spin very fast, last for few seconds before went back to normal.

On my right side the house is vacant, I asked my neighbor on the left and he said he didn't experience all that, which I doubt very much

When all these things happens, I never switch on/off anything. Nothing.
The only thing I turn on all the time is the fridge. I switched off and flickers still happen.

Should I just call tnb? These happen for a week already.
Anyone of you have this kind of experience?

Call TNB and ask them to check their sub-station.

It happened to me once and blown some of my appliances (including my neighbors).

Rempit stolen some metal parts inside the sub-station.

Borrow ur friend clamp meter and measure the voltage .
It should be +10 -6% variance from the 230v.

I measured and it is normal
But i can't see the peak voltage coming so I didn't measure at that particular moment

Just call the TNB.

Will do. Is it something to do with my meter and the two fuses around the meter?

If you have PC better plug it off until the fluctuation problem is fixed.
It can damage your PC especially hardisk.

Thanks for the reminder

Someone stealing neutral bar at the substation.
Report to tnb

In the mean time, be ready to kill the switches.
Else install a overvoltage relay to trip the main breaker

Bracing myself

Nope. Mostly from TNB.

Either like CKKwan explain or voltage coming not stable.

Your neighbour might not have the same problem because his line is another line.

I already called tnb. I stay in double storey Terrance house. Actually how they distribute the three phase wire?
