What are power surges and what they lead

As we all know, a long service appliance depends not only on the brand, but also on the quality of the electric power stored in the home network. And any radical and rapid voltage changes sooner or later lead to failure of the electrical equipment. In this article I will tell you the reason why there is stress and what it may bring.

Causes of

The cause of the sharp rise in voltage is sharp load shedding. For example, for some reason it turned off abnormally large plant, so at this time, the network will be an abrupt increase in voltage.

But it is not only a sharp load drop can affect the voltage. It is also a contribution can make and nature, such as a lightning strike.

consequences of surge

Any voltage drop adversely affects the electrical appliances included in this point in the network. As is known, normal mains voltage is considered in figure 220 with a tolerance of 10 percent and greater in the smaller side. Of course in appliances manufacturers provide surge protection, for example, stiralka when the voltage simply shuts down. But often built-in protection is not able to cope. As a result, we will have the faulty appliance.

The methods of struggle

In order to avoid damage to expensive equipment you can use the following tools:

- voltage relay. This machine also installed in the electrical panel. A principle of action it is that if a power surge occurs in the network, the relay just simply disconnects the house wiring from a common network, and after the voltage "ustakanilos" again connects network.

- Voltage regulator. This device protects the devices from the majority "trick" voltage and within the claimed range eliminates low or high voltage, and outputs the standard value of 220 V.

- bespereboynik. Sudden power outages are very bad moment, especially if you previously worked at the computer. The way out is to install an uninterruptible power supply or abbreviated - bespereboynik. It will allow to complete the work safely with the lights off and safely shut down, such as a computer. Apart from this it also eliminates the harmful effects of the so-called "pecks" voltage, extending the life of the instrument.

That's all I wanted to tell you about the overvoltage and ways to combat it. Thanks for attention.
