The meter shows E, is it broken?

Living at home is about budgeting. Our production and life are inseparable from the measurement of clothing, food, housing, transportation, water, electricity and heat. Speaking of measurement, Toutiaojun remembered a fan message in the WeChat background two days ago:

My home meter screen keeps on, is it broken?

A friend once asked Toutiaojun a similar question. Therefore, Toutiaojun consulted professionals.

The meter screen that fans are talking about is actually an LCD screen. What is the reason why the LCD screen of the electricity meter at home is always on?

The prompt "Requisition for electricity" is prompted

The meter has an alarm light, when your home appliance bill is less than a certain value, the alarm light will turn on, prompting you to pay the electricity bill, and the LCD screen of the meter will also stay on to remind you to charge the bill in time.

However, the remaining amount of meter reminders may vary from province to province, city to city, and even between customers and customers.

For example, the LCD screen of the electricity meter in City B will always be on when the balance of the electricity bill is less than 100 yuan. For low-voltage residential customers in City M, the screen will light up when the balance of the meter is less than 20 yuan.

In H city, the power supply company will agree on a certain amount with the customer, which means that your home and your neighbor's house may be different, and the agreement shall prevail.

If your home appliance meter shows a balance of 0 yuan or even arrears, the power will be automatically cut off at home. After the power outage, please recharge in time to restore normal electricity.

The battery in the meter is dead.

The LCD screen of some customers' home appliances is always on, and err-04** appears, which means that the battery in the meter may be dead.

The meter battery is responsible for the clock and will power the meter elements in the event of a power outage. The appearance of err-04** is that the meter prompts you that the coin cell battery inside is dead, but this does not affect the metering function of the meter.

In addition to err-04, there have also been mysterious numbers on the meters of individual customers' homes that ordinary people can't understand.

If you encounter the above problems, you can call the power supply service** for fault repair, or contact the service person in charge of the power supply area in your community, or go to the nearby power supply business hall to explain the situation.

The environment is too dark. There is also a situation where some meters are installed in a very dark environment, and in contrast, the LCD screen of the meter is very bright. This situation is caused by the external environment and has nothing to do with the meter.

The LCD screen of the meter is on, will it use my home's electricity?

Of course, what the little friend who asked the question wants to know most is, will the LCD screen consume my home's electricity?

No matter how bright the LCD screen of the electricity meter is, it will not use your home's electricity.

The power consumption of the meter itself is very small, and the power consumption of the LCD screen is extremely small. Since the wiring to maintain the operation of the meter and the power of the backlight indicator is connected before the metering collection, the power consumption of the meter is not included in the meter. Think about it, if the meter is connected to the metering collection, then if your home is in arrears and the power goes out, the meter will also be blackout, and you will not be able to remotely control the power outage.

In a nutshell, the electricity bill for the electricity consumed by the meter is paid by the electricity company.

If it is a smart meter, it self-checks, sends out a prompt, and there is a fault.

You can turn off the power and restart it. If it still doesn't work, it's broken.

E means error code, please notify the electrician or report to the power supply department!

Causes and solutions for broken meters:

1. Overload. Due to the small capacity of the billing meter, there are too many household appliances used and the capacity is too large, resulting in the long-term overload and heating of the current coil of the billing meter, which causes the energy meter to be damaged.

2. The insulation is broken down by moisture. Due to excessive humidity or leakage of electricity at the installation site of the meter, the insulation of the meter is reduced and the insulation breakdown is burned out.

3. The meter is burned out due to lightning overvoltage.

4. Burnout due to poor manufacturing and maintenance of the meter.

5. Due to mechanical damage due to external force, the meter is damaged by smashing it.

In order to avoid the subsequent impact on your electricity consumption and billing, please reflect to the owner of the meter in a timely manner, if you belong to the electricity customer of Guangdong Power Grid, please call the 24-hour power supply service **95598, and the power supply company will arrange staff to follow up.

We hope you find ours helpful.

Today, I would like to introduce you to the rich and handsome people of the meter family - smart meters. "Smart meter" smart meter is an electric energy meter with intelligent chip as the core, composed of measurement unit, data processing unit, communication unit, etc., with functions such as electric energy metering, information storage, real-time monitoring, active control, and information interaction. At present, most users use smart meters.

It can be said that smart meters are a key element of the smart grid. Press the white button on the smart meter, and the display will scroll through the information such as power, meter number, time, voltage, current, power, and power factor. When the words "Current Forward Total Electricity KWH" appear on the display, the number in front of kWh is the cumulative total electricity consumption from the time the meter is installed (0 kWh) to the time the customer checks the meter level, and the smart meter only displays an integer number of power levels.

In the lower right corner of the smart meter display, there is an "E" indicator, once the energy meter fails, the "E" indicator will be solid or flashing.

The reasons why the meter does not show up and how to fix it are as follows:

1. The meter is not powered on. Access conforms to the nameplate.

on the rated voltage.

Can. 2. The battery in the meter is under-voltaged. Replace the energy meter.

within the display battery.

3. The meter hardware is damaged. Seek technical support from the manufacturer.

Or replace it with a new energy meter.

The electricity meter is the abbreviation of the electric energy meter, which is used to measure electric energy, also known as the watt-hour meter.

Fire meters, energy meters, and kilowatt-hour meters refer to instruments that measure various electrical quantities.

How to view the meter:

Method 1: The general straight-forward single-phase meter and three-phase meter can directly read the number minus the last reading to be the amount of electricity at this stage.

Method 2: Through the current transformer.

The three-phase meter connected by the connection mode should observe the current ratio of the connected current transformer, and the number read on the meter multiplied by the current ratio is the measured amount of electricity, and the accurate loss and line loss should be added.

Method 3: The smart meter only has an LCD screen, and if it is a single phase, it will directly display the total power and remaining power, and you can read it directly. If it is an IC card meter, the light-emitting tube display is a single graphics card table, and the red dot jumps to the total use is the total use, and jumping to the remaining is the surplus.

Dual graphics card table, read above or below can be.

The meter shows E-03, what's wrong, is it broken?

The meter shows E-03, what's wrong, is it broken? The meter shows E03: Relay failure The meter failure generally appears on the prepaid card meter indicating that the card is initialized wrong, you will replace the card in the correct position and insert it, if this error is displayed every time**, it means that the electric card needs to be replaced, it depends on who you pay for your electricity bill, if it is handed over to the power supply company, you must apply to the power supply company to quietly replace the card, if it is a property company, you must buy a card in the property company.

Hello dear! The meaning of the electric meter showing the stove E4: When the single-phase smart meter shows ERR-04, the alarm light and LCD screen are always on, this is because the clock battery voltage indicated by ERR-04 is insufficient.

When the above faults occur, the customer generally does not need to deal with it by himself, and only needs to pass the 95598 guaranteed foot banquet repair. Because the meter is the asset of the power supply company, the power supply bureau will deal with or replace it free of charge in case of failure. Hope it helps!

Possible causes

1. It is possible that the switch in the house is larger than the switch of the meter, and the electricity consumption is often overloaded (relative to the switch of the meter entering the house);

2. Another possibility is that the wired insulation between the switch in the house and the switch of the meter is damaged, and the power consumption will cause a short circuit fault;

3. Another possibility is that the wire of the switch of the household meter is loose and needs to be tightened.

Protection of home circuits.

The first line of protection is the sub-switch of each circuit in the home distribution box. This switch is also a protective measure at the end of our electricity. For example, almost all the socket circuits in our home are leakage protection switches.

For the lighting circuit in the home, almost all of them are selected air switches.

The second line of protection is the main switch in the home distribution box. According to the different choices, the main switch is actually divided into two situations: one is the air switch, and the other is the isolation switch.

Both of these switches can be used to control and protect the various branch circuits below to meet our requirements for safe electricity and operation safety. Burnout.

The third protection is the main gate at the lower mouth of the meter in the outdoor public meter box. All the electricity in our family is connected from the lower mouth of the meter, and first of all, there is a main switch at the lower mouth of the meter to connect our indoor electricity. Therefore, our indoor electricity is protected by this main gate.

The electricity meter at home has an err-04 failure**Don't panic, generally this situation is that the meter that has been used for a long time will have this situation, indicating that the clock battery voltage is insufficient. That is, the battery inside is out of power, and after a long time, the meter will be slid in the middle of the stream. What should I do if my meter fails?

If there is an error in the general meter, the user does not need to deal with the fault by himself, and needs to ask a professional to deal with it, and only needs to pass the 95598 warranty. Because the meter is the asset of the power supply company, the power supply bureau will deal with or replace it free of charge if it fails. Problems with err-04 faults** in the meter:

1. If it happens for a short time, the power will be out. That is an indication of a short circuit or design issue inside the meter. 2. This situation can only be solved by the original factory.

Because once this battery is dead. It will lead to many problems such as wrong time scale for power accumulation, wrong storage location and so on. 3. After replacing the battery, you need to recalibrate the clock, and there is also the processing of lost data.

Error in the meterCommon faults**Explanation: err-01: Fault -- Control loop error.

err - 02: Fault --ESAM error, note that the card chip is - 03: Fault --Prepaid card initialization error.

ERR-04: Fault -- The battery is undervoltage and the battery inside the energy meter has no power. err - 05：

Failure -- an internal program error. ERR - 06: Fault -- Memory failure or corruption.

In order to avoid the subsequent impact on your electricity consumption and billing, please reflect to the owner of the meter in time, e07 is the meaning of error, indicating that the electronic meter does not detect the signal of the safety lock, whether the magnetron is damaged, whether the position of the magnetron is correct, whether the magnetor is placed at low speed and normal high speed. Solution: Restart the treadmill, if the problem is not solved, you can contact the maintenance personnel.
