A voltage stabilizer can help with flickering lights, voltage drops and appliance shutdowns, but the cause should be diagnosed first.
An electrician should measure voltage at the input, panel and problem sockets under load. If the issue is a loose contact or old cable, a stabilizer will not fully solve it.
It can protect refrigerators, computers, boilers, pumps and other sensitive equipment from voltage fluctuations. Capacity and installation point must match the real load.
If lights flicker, sockets get hot, breakers trip or appliances shut down, the panel, cable, contacts and load should be checked.
