High Voltage!

Aslamualikum All! Recently there has been a transformer problem in our area leading to increased voltage. Many fans and other electrical applicances have been burnt due to high voltage. I would like to know is there any device to prevent appliances from the affects of high voltage. I know about stabilizers but not every single electrical applicance can be connected with a separate stabilizer. Do circuit breakers serve this purpose!?.. Your kind suggestions will be appreciated.

directly connect your main line to a large stabilizer, in that case all your appliances will be protected with one single stabilizer and it will prevent over and under voltage

also, there are Surge protectors, eg Belkin makes them, . you will have to put one at each device..
