Which site can give me the schematics for a 160 v. ac to 230 v. ac step-up single phase transformer?

Question

The voltage level at my residence is only 160 v. during peak hours, though theoretically it is expected to be at 230 v. Can someone tell me which site can give me the detailed schematics for a single-phase step up transformer for 160 v. to 230 v. with surge protection?

Answer 1

You don't want a transformer, you need a voltage regulator.

Don't try stepping up the voltage yourself, it's dangerous to everything electric in your home, not to mention expensive.

Call the utility company and get someone to check your supply for brown-outs. Your agreement to purchase electricity should be for a constant 230 3-phase VAC delivered to your meter box 100 % of the time. If you live at the end of a long circuit, the power company should install a regulator type isolation transformer. Bear in mind that "constant 230" and "100%" are relative terms, and that nothing in electronics is perfect.

It may take some convincing on your part because isolation transformers are expensive for the power company, too.

Answer 2

No schematic required, it's just a transformer with 160 volts on the primary and 230 volts on the secondary. You need to specify the power or current.

But I don't think you want to go that route. There may be times when the input is at 230, and then the secondary will go up to 330 volts, and even momentary voltages that high will burn out your appliances and lights.

You need a voltage regulator (or stabilizer), possibly combined with a UPS for when the power goes out totally.

But first talk to your power company and find out what the basic problem is and how to solve it. You are paying for that lost 70 volts.

If you do go the regulator route, carefully decide what needs to be regulated and what does not. Then purchase a regulator of the correct size.

My first concern is why is your voltage so low?

In any developed country, your power company would be responsible to provide you with the correct voltage. It they don't then there is a problem that needs to be corrected. There could also be a problem in your house such as loosing the neutral. This would show up as a low voltage, depending on what is turned on ( in the US, we have a 2 phases with a neutral. 240 across both and 120 to each side).

Then comes the problem, when the 160 comes back to 230, your step up transformer will come up to around 300. As for a form of regulator, if you run electric water heater, electric stove or electric heat, you will need a very large device.
