There was a sudden power outage at home and there was no tripping

What happened to the sudden power outage at home without tripping, the sudden power outage at home, the switch box in their room did not trip, this is the main switch in the corridor tripped, the main switch was empty, it will be automatically closed immediately after tripping, if you jump again, he will not close, so you don't see your own trip.

Summary. 1. There is a problem with the line, it may be that the line is not connected well, resulting in ignition and a short-term power outage, but once the line is stable, it will be connected by chance, it is recommended that you pay attention to every wire connection part in the home, and feel whether there is a fire phenomenon or overheating. 2. The zero line is broken.

Test it with a test pen, the two holes of the socket, and the light of the test pen must be on. To see if there is electricity in other people's homes, it is best to look at the place where the zero line and the main zero line are connected, usually the probability of problems appearing here is higher, especially when using high-power electrical appliances. 3. It should be the line break, the treatment method, add a resistive load, such as an incandescent lamp, (turn on the light control switch) and then measure the resistance value of the switch (must be powered off), and the fault can be judged.

Finally, find the lights or sockets in sections. 4. The meter is broken. If you have a universal meter at home, you can test it yourself, and the voltage at the inlet of the universal meter reaches 220V, which means that the power outage caused by the broken meter.

If you have a problem with the meter, you need to find a professional electrician. 5. It may be caused by the loosening of the clamp screws of the lamp switch or the main power switch. Once the wire is loose, it will cause the phenomenon of being connected or not connected, it is normal when there is no electrical appliance or low-power electrical appliances are used, when you turn on the light, due to the increased load, the clamp screw part will be ignited and accompanied by a sizzling sound.

Reason 1: If there is no electricity in the community, it is a power outage caused by the power supply stopping; Reason 2: Long-term use of high-power electrical appliances or aging lines; Reason 3: The wire at a switch in the home is disconnected; Reason 4: Power outage due to damage to the electricity meter.

There was a sudden power outage at home and there was no tripping

The first reason that can be thought of for a sudden power outage in your home is that the meter trips. At this time, you only need to dial up the jump at the main meter. If you can't flip it, you'll need to turn off all the switches and try again.

If it weren't for the meter tripping, then the possible causes of a power outage are as follows:

1. Collective power outage

If the power is not lost due to tripping, it is best to go to a neighbor or an upstairs or downstairs household to ask if there is a power outage. If there is a power outage upstairs and downstairs, it is possible that the power supply station will be collectively cut off.

Generally speaking, if there is a temporary power outage, the property and the community will make a notice or notify the property group. It's best to pay attention to whether this is the reason.

2. The use of high-power electrical appliances

After checking for a power outage that wasn't caused by a tripping meter, it's time to check if there are high-powered appliances in use in your home. Long-term use of high-power appliances or aging lines can lead to power outages.

3. The switch is disconnected

Or you can check the switches in your home. Take a small light bulb and connect it to the binding post of the switch, and the light bulb is on, indicating that the switch is broken. At this time, you need to find an electrician to repair it.

4. The meter is damaged

If the power outage is not caused by a tripping meter, it may also be a power outage caused by a damaged meter. In this case, just go and check the meter.

A universal meter can be used to test the voltage at the incoming line. If the voltage at the incoming line reaches 220V, it means that the meter is damaged and the power is out.

There was a sudden power outage at home, but it didn'tTrippingThere was no power outage either: it could be a faulty power cord, causing a power outage in the neighborhood and surrounding areas. However, if there is electricity in the hallway or adjacent house, it means that the wiring in your home may be disconnected or the connection is faulty.

It is advisable to find a real estate company or a professional electrician for verification.

Household electricity needs precautions:

1. We can't see electricity in life, but in fact, all electrical appliances have a constant load. When designing home circuits, owners should use square roots.

To select the right size wire based on the total electrical load (e.g. electricity used for lighting), metric copper core wire is sufficient.

2. In order to ensure the safety of household electricity and facilitate future maintenance, the circuit should be separated according to the purpose of lighting, kitchen sockets, water heaters, etc., and if one of them fails, the other can continue to be used to work.

3. According to the relevant introduction, it is necessary to install a short-circuit protection device in the home circuit to make it automatically trip when the circuit fails or the equipment leaks, so as to ensure the safety of the power supply circuit and avoid electric shock accidents.

4. The premise of ensuring the safety of household electricity is to use general electrical products, such as: wires, switches, lamps and other electrical equipment, therefore, do not buy products with poor greed and poor quality.

Summary. If there is a sudden power outage in your home but there is no trip and no power outage, the reasons are as follows:1

Power failure: A power failure causes a computer or other electrical appliance to lose power suddenly. You can check if the power plug is loose or try replacing the power supply.

2.Wire Fault: Aging or damage to the wire that causes a short circuit or power outage in the circuit.

You can inspect the wires for damage or age, and if you need to replace them, ask a professional electrician to replace them. 3.Fuse failure:

A faulty fuse causes a short circuit or loss of power to the circuit. You can check whether the fuse is burned or loose, and if you need to replace it, ask a professional electrician to replace it. 4.

Appliance failure: A sudden power outage due to a malfunction of the appliance itself. You can check if the appliance is working properly, and if you need to replace it, please find a professional repairer to repair it.

Hello dear, if your home suddenly loses power but there is no trip or power outage, then there may be the following situations:1Brief blackout:

Sometimes, utilities will overhaul or upgrade power lines, which can cause short-lived power outages. If this happens only once and for a short period of time, it usually doesn't have much of an impact. 2.

Input power failure: If your computer, TV and other devices suddenly shut down, and other devices can still be used normally, then there may be a problem with the input power of the device, such as loose plugs, aging lines, etc. In this case, it is necessary to check whether the power cord of the device is plugged in, whether there is a burning smell, etc.

Hail potatoes 3Home circuit failure: If multiple devices in your home are not working properly, then there may be a fault in the home circuit.

In this case, you need to check whether the circuit is tripped or short-circuited, and you can also try to check the status of the circuit switch at the meter. 4.Power supply transformer failure:

If there is a power outage in your neighborhood or street, it may be that the power supply transformer is faulty. In this case, you need to contact the local power supply company in time to deal with it. In short, if there is a sudden power outage at home but there is no trip or power outage, you need to confirm whether there is a problem with a single device, if there is a problem with multiple devices at the same time, you need to check the home circuit or the power supply transformer and other problems, and contact professionals in time to deal with it.

Summary. Hello dear relatives are now installed in the home is an air leakage switch, in the case of short circuit, leakage, leakage will automatically trip. If there is a sudden power outage in the home but it does not trip, it should be caused by a problem with the power supply in this area.

First, check whether there is electricity in the house next door, neighbors, streets, etc. If there is none, there is a problem with the power supply line. If only your home has a power outage, it means that there is a problem with the wiring at home, and the main switch should trip by itself.

See if the leakage switch at home has tripped, if not, it means that there is no problem with the circuit and electrical appliances at home. At this time, we use an electric pen to measure the circuit on the light to see if it is still charged, and after confirming that there is no electricity, we will knock down the switch of the switch switch and completely cut off the power supply.

Hello, dear and popular, the safe operation of the tripping system of the traction power supply system that supplies power to the electric locomotive should be guaranteed. In the event of an accident, the relay protection device installed in the traction substation (opening and closing station, partition pavilion) will be activated by the short-circuit current generated by the accident, and the circuit breaker that supplies power to the accident point will be automatically disconnected to reduce the scope of the accident and ensure the safe operation of other pure equipment and the normal power supply to the non-accident line. This action of automatically disconnecting the circuit breaker due to an accident is customarily called "tripping".
