Why is it that all of a sudden all the lights in the house are flashing and then all the power is go

The zero wire must be broken, and some of the sockets at home are connected in parallel, and the wires may not be connected for a long time. Unplug all electrical equipment in the house, turn off the switch, and the zero line should be no longer electrified.

How it works

Electric light is a device that converts electrical energy into light energy to provide illumination, which appeared in the second industrial revolution.

Here's how it works:

When the current passes through the filament (tungsten filament, melting point above 3000), heat is generated, and the spiral filament continuously gathers heat, so that the temperature of the filament reaches more than 2000, and when the filament is in an incandescent state, it emits light like red-hot iron can shine [2]. The higher the temperature of the filament, the brighter the light emitted.

Therefore, it is called incandescent lamp.

From the perspective of energy conversion, when the lamp emits light, a large amount of electrical energy will be converted into heat energy, and only a very small part can be converted into useful light energy. The light emitted by electric lamps is panchromatic light, but the proportion of each color is determined by the luminescent substance (tungsten) and temperature. The imbalance in proportions leads to a color cast in the light, so the color of the object is not realistic under incandescent light.

History of Invention. The earliest practical electric light was the incandescent lamp, but long before the invention of the incandescent lamp, the Englishman Humphrey Davy.

The arc lamp was made with 2,000 batteries and two carbon rods, but the arc lamp was too bright, produced too much heat, and was not durable, and could not be used in ordinary places.

In 1854, the German watchmaker Henry Goebel emigrated to the United States.

Using a carbonized bamboo wire placed in a vacuum glass bottle, he made the first practical electric lamp, which lasted for 400 hours, but he did not apply for a patent in time.

In 1860, the Englishman Joseph Swan also made a carbon filament electric lamp, but he failed to obtain a good vacuum environment that allowed the carbon filament to work for a long time. It was not until 1878, when British vacuum technology developed to the extent that it was necessary that he invented a light bulb powered by carbon filament under vacuum, and obtained a British patent. Swan's own house was the first private home in Britain to be electrically illuminated.

In 1874, two Canadian electrical technicians applied for a patent for an electric lamp: nitrogen gas was filled under a glass bubble to emit light with an electrified carbon rod, but they did not have the financial resources to continue perfecting the invention, so they sold the patent to Edison in 1875.

Edison bought the patent and tried to improve the filament, and finally in 1880 he made a carbonized bamboo filament lamp that could last for 1,200 hours.

There is a leakage in a place, or you have a short circuit in a place, and your live wire is not in the protection, and the protection is disconnected from the neutral line, which is very dangerous.

Why is it that all of a sudden all the lights in the house are flashing and then all the power is gone?

Hello dear! Suddenly all the lights in the house flashed and then all of them were out of power because of the short circuit of the main line, and the missing search manuscript was protected by the electricity At this time, the power should be cut off in time, check the insurance, and check the main line circuit! In general, the main reasons for the fact that the lights at home are not lit at all are:

Power outage, power supply bureau because of the rush to repair the circuit, bad reputation disturbance and other reasons, 1, maybe the power quality is not good, when the computer is turned on in the Qing Leak, there may be any electrical appliances in the room or at home that have been turned on, the most suspicious is the tube light, the moment the light is turned on, the contact of the power supply, produced an electric wave, and this radio wave impacted the power supply and motherboard of the computer.

Why is it that all of a sudden all the lights in the house are flashing and then all the power is gone?

Hello! Suddenly all the lights in the house flashed and then all of them were out of power Reason 1, there is an error in the wiring, that is to say, the neutral wire and the live wire are connected wrongly, and then the circuit is reconnected. 2. The voltage of the electrical appliances used at home is too high, resulting in unstable voltage.

3. The contact between the power supply and the lamp is poor, and the current is not smooth, which will cause the lamp to flicker and flash. 4. The current of the neutral line is too large, resulting in the neutral line being electrified.

The causes and solutions of flashing lights are as follows:

1. The neutral line and the live wire are reversed.

Solution: Check whether the red line at the switch is red, if not, consider that the switch may control the zero line, if it is confirmed that it is reversed, adjust it immediately, and switch the light and switch wire;

2. Observe the flashing lights, whether there are multiple lights flashing in the room, and these lights belong to the same circuit, it is necessary to consider that the zero line of the electric box and the live wire are reversed.

Solution: Swap the two lines at the lower mouth of the circuit breaker, and be sure to mark them after the adjustment, and the line color of the neutral line and the live wire in this circuit is exchanged, so as not to affect the maintenance in the future.

3. If the neutral line and the live wire are not reversed, it may be that the lamp generates self-inductive current, in this case, the flickering frequency of the LED lamp is relatively high, and the flickering frequency of the fluorescent lamp is relatively low.

Solution: Switch to an incandescent lamp, or buy a 220V relay and connect the relay coil in series to the circuit to absorb the induced current.

This happens because of the unstable current in the incoming power grid. It is advisable to observe for a while longer, there is no need to find an electrician.

Find the decoration company for your decoration, it is a matter of the line, and there is a reason that the voltage is unstable, buy a voltage regulator, but the second situation is relatively rare.

Yes, find an electrician, the main circuit is virtual.

Or maybe the voltage is unstable.

If you have a place near you that has high voltage, it will suddenly disappear, and the voltage will become unstable, etc.

Let's ask an electrician to take a look.

He doesn't take money if he doesn't have anything to do.

Summary. Hello, this is because the voltage is unstable, flashing causes the lamp to be one, and the voltage is too large in an instant, which will cause the electrical appliances at home to burn.

Why is it that all of a sudden all the lights in the house are flashing and then all the power is gone?

Hello, this is because the voltage is unstable, flashing causes the lamp to be one, and the voltage is too large in an instant, which will cause the electrical appliances at home to burn.

If there is no electricity near your home now, it means that there is a fault in the power supply line, and wait for the call to check whether the electrical appliances in your home are damaged.
