How to Control Home Incoming Electrical Power?

Sounds like you need some form of power conditioning.....

that is a pretty broad term though. Could you describe the types of electrical problems and anything you might have noticed about how the appliances fail?

I describe like this.

Incoming Power is 240 VAC single phase.

Every thing in house working good.

All of a sudden from main line some disturbance is occurs in main transformers where the electric power distributed in area.

It fuses so many houses light, fans , TV and other.

But somewhere in the same distribution not a single appliances even light bulb.

I suspect phase changing or something else as i am not an electrician.

I want my hose to prevent from it.

How to do?

Neutral is getting disconnected on the pole.

Have you looked into residential surge suppression devices?

This is one way to protect your equipment/appliances.

This could get costly though.

Depending upon the severity of the surge/spike event, this usually (but not always) takes out the MOV's (metal oxide varistors).

Here is a pretty good read for you.

There are different types of surge suppressors available also. Here is another good read.

As gmphadtw pointed out, you may also have a floating neutral. IMO the most cost effective route would be to check (or have someone with experience do it for you) the integrity of the neutral connection(s).

To get a more clear picture connect(hire) a power analyser after the utility meter and record all parameters(V,I,instantaneous,Hz,Pf,THD,kw,Var,kVA etc) of your supply.
