Both the live wire and the neutral wire of the meter are electrified, if the electrical appliances cannot work normally, it means that the neutral wire is disconnected.
The neutral wire is not charged in normal working condition. with a multimeter.
The voltage gear measures the neutral voltage of the live wire, and if there is no voltage, it means that the circuit is open.
When the remaining power in the meter is equal to the alarm power, the power will be turned off and the alarm will be turned off, and the user can restore the power supply by swiping the card in the sensing area; When the remaining power is zero, the power will be automatically turned off, and the user must pay the card again to purchase electricity before the power can be restored.

Both the live wire and the neutral wire are powered because the neutral wire is broken. That is to say, the current starts from the live line and passes through the electrical appliances returning to the earth from the zero line, and now the zero line is broken and the current cannot be returned, so it stops on the zero line that has been broken, and the phenomenon that both wires are electrified. In technical terms, it's often called no loop.
The plug-in board does not have an indicator light, showing that the plug-in board has a point, which is mostly because the plug-in board is dirty, such as the water has entered, and after it has dried, in the state of power failure, the multimeter measurement has no short circuit, and the resistance is infinite, but even if it is a resistance of tens of megaohms, the AC circuit of 220 volts will have several microamperes of current, so this situation is enough to light up the test pen, and mistakenly judge that the zero line has electricity.

Hey! First of all, the lights in your house are still on normally!? If it is not lit, it is a typical fault of the zero line break, and the zero line in the incoming line is broken or not connected.
If the lights in your house are still on, then what do you use to measure the electricity!? Voltage tester? Then check if there is a problem with the zero line that you should have grounded, and it has not been grounded.

Both the live wire and the neutral wire are electrified, what's going on? 1.If the electrical appliance is plugged in, the electrical appliance can be used, which is caused by the three-phase imbalance of the transformer;
2.If the electrical appliance is plugged in and the appliance cannot be used, it is caused by zero breaking;
3.After the power failure, if the zero line of the fire wire is live, it is caused by the wrong wire connection of the leakage protector that is constantly zero in the fire.

Hello, there are probably three reasons for this. : The zero live wire caused by the zero wire breaking is electrified.
Because the circuit in our home is formed from the live wire to the neutral line. If there is a break in the neutral line, then no loop can be formed between them. This is where the situation arises from the live wire to the neutral line and then through the electrical appliance.
You can't return to the earth from the zero line, and you can't return after the circuit is broken. So it stays above the zero line. This leads to the phenomenon that we commonly see that both wires are electrified.
In fact, there is another point, that is, the service life of the wires in our homes is still long, and the insulation layer of the wires is aging due to the harsh use environment. At this point, there is a leakage of electricity in the wire, forming a closed loop.
That is, the zero line and the live line, which are fundamentally out, did not form a normal fall, and there was a connection in the middle. : Finally, the whole impedance of the neutral line is too large.
For example, the most common reason is that we are not firmly connected at the position of a certain outlet, resulting in poor contact. Because of the poor contact, in fact, the zero line can still work, but it produces a large impedance. In this case, a certain voltage to ground is generated, which is what we call the neutral line charged.
Solution: Find the situation of the entire circuit after the power is off.
Because the first thing we should determine should be the total zero line open in the room. Therefore, at this time, we should follow the neutral line from the live neutral line to our indoor main switch, that is, the location of the indoor distribution box. In this way, we can basically find that there may be a zero disconnection at a certain location.
After we find the disconnected position, we reconnect the neutral wire as required. Then try powering it on. Basically, this is something that can be solved like a home circuit.
For example, the simplest point is that the part of the electrical wire connection is loose. In fact, this is also a kind of poor connection. Or a loose connection to the air switch or circuit breaker, as loose contacts can also cause this.
Therefore, it is necessary to find all the connection joints in the room again, so as to ensure the normal power supply. : When we judge that the main neutral line is not disconnected, and there is no bad contact, then it may be that there is a problem with the insulation of the wires at home.
In other words, there is a serious leakage at this time. In fact, if we install a qualified and effective leakage protection switch, should it be tripped in this case? If an air switch is installed, it may not trip.
In this case, that is, there is leakage, I personally recommend that you shake and measure the insulation resistance value of all wires in the indoor circuit. For example, the insulation resistance value of household wires should be above, if the measured value is lower than ohms, then it means that there is a problem with our wires. At this time, the method adopted is to change the unqualified wires.

The reason why both the live wire and the neutral line are charged with the electric tester is that the mains 220 AC power supply zero line is open, and the live wire is transmitted to the zero line through the electrical appliance, so the live wire zero line electric tester is electrified.
-
Neutral wire electrification is a manifestation of poor grounding, and most of the reasons for neutral wire electrification are either broken or bad contact, and of course there are other reasons.
Other reasons for this are:
1. When connected to the power grid, it is grounded in order to protect the electrical appliances, so that the neutral line is electrified;
2. Some beginner electricians directly grounded the neutral wire;
3. The zero live line is connected together;
4. The three-phase load is unbalanced, so that the zero line potential drift is generated, with voltage.
-
In this case, the circuit is connected to an electrical appliance with a closed switch, and the neutral line is broken. There is no current path on the upper line of the electrical appliance, and the electrical appliance does not produce a voltage drop. So the upper zero is also electrified.
-
The zero line of the jack with the problem has poor contact, not broken or poor contact, originally the zero line is not electric, but if the plug-in board has an indicator light of a light-emitting tube, the electricity of the live wire will be strung through this indicator light. In this case, both the live and neutral wires are electrified.
-
If both the live wire and the neutral line have computers, it is not certain which sentence will be short-circuited or where the power is off, you can check which place has power over?
-
It is to break the neutral line or connect the switch to the neutral wire.
-
It should be a mixed line, and it needs to be checked thoroughly.
-
This is a typical neutral disconnection fault.

What does it mean that both the live and neutral wires of household meters are electrified?
Ammeter**. This problem means that there is a problem with your home's power line!
The focus is to check and eliminate the zero line disconnection point, so as to find and solve problems in time and reduce the potential safety hazards caused by accidents!
Remember! Be sure to pay attention to safety when inspecting and repairing.
-
If there is a situation in the family where the zero line on the meter is live, then it is usually caused by the disconnection of the zero line in the household. It is recommended that you find an electrician in the village. Door-to-door inspection. Maintenance. to be able to use electricity normally.
Hope mine is helpful to you, hope, thank you.

The zero line at the front end of the meter is intact, and the zero line at the back end of the meter will not be electrified, only the zero line at the front end of the meter is broken, and the live wire will be transmitted to the zero line end of the meter through the voltage coil in the meter.
-
Very simple! The only reason why both the live line and the neutral line are "electrified" is that the neutral line is open!
-
Due to the zero line broken circuit or false contact, the line should be inquired in the direction of the entrance line.
-
The zero line of the meter is live, indicating that the zero line at the front end of the meter is broken.

Summary. The second reason: the zero line is broken, for this case, for example, after the power is sent, the electrical appliance does not work, and then use an electric pen to measure the 2 binding posts of the electrical appliance, if the live wire and the neutral wire are live, it is the neutral line is disconnected at a certain position.
Solution: Find the position of the wire joint, whether the zero line joint is open, or check the lower mouth of the electric switch, the zero line is not compressed, find the position of the zero line break, and connect it.
What is the reason why the live wire and neutral wire of my home appliance are electrified?
Hello wait a minute<>
The first reason: the power supply system in the three-phase live wire or current unbalanced, although we use single-phase electricity at home, but the transformer power supply is three-phase electricity, three live wires, a neutral wire, if the current on the three live wires is inconsistent with the blue words, then Pei Ju will lead to the current imbalance of the three-phase live wire, then the neutral point will be offset, so the neutral line is charged at this time.
The second reason: the zero line is broken, for this case, such as after sending electricity, the electric Ming Kaihu device does not work, and then use an electric pen to measure the 2 binding posts of the electrical appliances, if the live wire and the zero line are excited, it is the zero line in a certain position to sell the solution: find the position of the wire joint, whether the zero line joint is open, or the lower mouth of the electric switch to check whether it is, the zero line is not compressed, find the position of the zero line broken, and connect it.

What is the reason why the live wire and the neutral line of my home appliance are electrified, hello dear, can the zero-wire live household appliances work normally. If the codeseller cannot be used normally, the neutral line is disconnected, and the neutral line is broken. Check the switch fuse at the re-detection point and check whether the neutral line is falsely connected.
If it works normally, it means that the three-phase load is unbalanced, resulting in an unbalanced current on the neutral line. It is necessary to balance and distribute the three-phase load on the total power supply as much as possible. I hope I can help you!
If my answer is helpful to you, please also give a thumbs up (comment in the lower left corner), look forward to your praise and failure, your efforts are very important to me, your support is also the driving force for my progress, and finally I wish you good health and a happy mood!
