Voltage stabilizer

Quite often you can hear or read that a device such as a voltage stabilizer is very important and needed for every house or apartment. But what is its role and is it really necessary? Let's figure it out together.

What are voltage stabilizers used for

As it becomes clear from the name, a stabilizer (you can also find the name: "voltage regulator") is needed so that we get 220V at the output. And given the fact that voltage is a variable parameter, we do not always have the ideal "two hundred and twenty".

Sometimes deviations can be insignificant and within five percent are even considered the norm. But more and more often, 200V, 180V, or 240V can be fixed in our sockets. What are these numbers fraught with, and what problem will we solve if we buy a voltage regulator in this case?

The fact is that for most devices, exactly 220V is not required for normal operation and small deviations are acceptable. However, if the voltage is too small or too large, the device will not even be able to turn on. Let's look at an example.

You want to turn on the washing machine, but the outlet is only 170V. Because of this, household appliances do not start, but still continue to consume starting current. The engine is standing still and starts to get very hot, which can cause serious breakdown and costly repairs.

But if you have a voltage rectifier, then you can not be afraid of such troubles, because at the output you will always have a current parameter close to the ideal value of 220V. This is the essence of the stabilizer's work - to protect your equipment from voltage surges and overheating, which significantly affects the service life of the devices.

How to identify voltage drops?

Sometimes there are clear signs of fluctuations in the current parameter. For example, regularly blinking light bulbs indicate voltage that "jumps". But, unfortunately, most of the time we are not even aware of such a problem.

You can solve it by calling the wizard or by purchasing a multimeter device, which will allow you to measure the voltage in the outlet with the help of probes. In this case, it is very important to do the measurement several times over the course of 2-4 days in order to get a clearer picture. If 220V is not even close, then you just need to buy a voltage stabilizer.

What types of device are there

Basically, these devices are divided by the type of stabilization, by the number of phases and by the method of installation. By the type of stabilization, one can distinguish:
