How dangerous breakage of the neutral conductor
Interruption of the neutral conductor - behind this short phrase lies quite dangerous phenomenon, not only signified able to bring down your entire consumer electronics, but also a real threat to your health and even life. In this article I will discuss the causes of this situation, as well as how to protect themselves from the negative consequences of breaking the neutral conductor.
Breakage in a three-phase and single-phase network
First, let's find out what consequences arise in case of interruption of the neutral conductor in three-phase and single-phase network, and start with trehfazki.
If breakage occurs in the three-phase network, for example on the main board of an apartment building, then we are faced with such a phenomenon as a phase shift.
Schematic representation trehfazki in normal mode:
The circuit is broken at neutral conductor
This means that the outlet may appear as a low voltage of 0 or higher, and high, up to 380 V. And as you know all our electrical naminal performed at 220 volts and such abrupt change would cause the failure of all, that at this moment has been connected to the network.
Breakage in a single-phase network
So, we have found that to break ground in three-phase systems suffer mainly electrical equipment, but to break ground in the single-phase supply, the situation is somewhat different.
In this embodiment, AC mains voltage is lost, but there remains a lethal potential of 220 V. And he will be present not only in the phase conductor, but also at zero.
But the danger of this phenomenon lies in the following: if you have implemented the so-called protective earth and neutral.
In this case, all the housing appliances, these should connected at this point in the network will be under stress. And if you are in this moment accidentally touch the metal housing, for example, will begin to pull out of the linen washing machine, you will get an electric shock, which can lead to a very sad consequences.
If you have a grounding, vanishing not, in principle, or have implemented a full-fledged ground, there is nothing wrong with your health will not happen.
Important. Here, the variant, when a disconnection occurs directly in the distributor plate, if zero otgoraet, for example, on the chandelier, it fails only that section of the network, the rest of the wiring remains intact and preservation.
How to find open
So, we have considered the question of what happens in case of interruption of the neutral conductor, now let's learn how to find the site of injury.
The best option would be to call a specialist course, but if you decide to try and find their own remove the cause, you should start exploring with your electrical panel, you can see there's a picture
If, however, in the panel's all right, it is necessary to examine all junction boxes, perhaps one of the twists over time weakened, overheated and there was lost contact.
If such inspection did not give results, it is possible to break occurred in the wall, and to find such damage would require a special device
In this case, you can not avoid a specialist call.
How to protect yourself and the house
In order to protect yourself and your property from a similar situation, you should install a dedicated device, called the signified voltage relay.
Another option is to install a voltage stabilizer with protection function of the undervoltage and overvoltage.
That's all I wanted to tell you about this dangerous phenomenon as breakage of the neutral conductor. Thanks for attention.
