Is it just areas of Lamai, or more wide spread.

Yesterday, and all of last night, the voltage dropped off to 50 volts on many occasions, even zero at times.

Fortunately I have 3 phase and water pumps and fridge kept running, but the phase that my bedroom lights, sockets and fans run on was the problem.

Anyone else experiencing the same?

yep...welcome to samui and its world class infrastructure

No problems in the Bophut/Maenam area... unless it's raining, or it's windy, or it's a day that ends in "y".

this is usual in samui, don't worry most of the time it's only around 90 volt that you get when there's a "power failure" .

doesn't make any difference amost for recent electrical appliances.

Probably one of the phases went down.

When this happens, the remaining healthy two phases tend to "leak" into the down phase through the local step-down transformer (usually 33Kv -> 230v), resulting in approx 170v supply for each of these two.
