How does the meter look at the power, and how does the meter look at the electricity?

Method 1: Directly call up the current power data (applicable to smart meters installed in the power department).

Press the button on the meter to switch the content displayed on the screen until the unit on the right side of the meter screen is only the word "kw", at which point the number on the screen is the electricity power, and the unit is kilowatts.

Scheme 2: Calculate the flashing period by pulse indicator (applicable to all electronic energy meters).

First, find the pulse constant of the meter (generally printed on the front of the meter, the unit is a data of imp kwh), and then use the stopwatch to measure the interval (in seconds) between two consecutive flashes of the meter pulse indicator (a red light that flashes from time to time), and use the following formula to calculate the average power (in watts) between the two flashes:

p=3600000 pulse constant The time interval between two flashes.

Press the flip down button of the meter button, the LCD display of the following electricity will appear, we will first explain the LCD display of the electricity amount, as follows:

The current total positive active electricity (, is the total amount of positive active electricity accumulated by the meter from the beginning of electricity consumption to this month. It means that the cumulative amount of electricity by this month has reached the degree.

The current positive active power consumption (which is the total amount of positive active electricity consumption accumulated by the meter from the beginning of electricity consumption to the peak period of electricity consumption in this month. Peak electricity is the amount of electricity used to measure electricity consumption during peak hours. For example:

The peak hour set by DTZ341 is (19:00-22:00), and the electricity used during this time period is all sharp electricity, and the unit price of electricity is more expensive than the usual unit price of electricity (the specific amount of electricity depends on the local charges).

The current forward active peak electricity (refers to the total amount of positive active electricity consumed by the meter from the beginning of electricity consumption to the peak hour of electricity consumption in this month. Peak electricity is the amount of electricity used to measure peak electricity consumption, and the time period varies from place to place. For example:

The peak hours set by DTZ341 are (08:00-11:00; 15：

00-19:00), the electricity used in this time period is peak electricity, and the unit price of peak electricity is more expensive than the usual unit price of electricity (how expensive it depends on the local charging situation).

The current positive active electricity consumption (refers to the total amount of positive active electricity consumption accumulated by the meter from the beginning of electricity consumption to the peak period of the electricity consumption level in this month, and the average electricity consumption is the electricity consumption during the peak period of the metered electricity level. For example, the weektime period set by dtz341 is (07:

00；22:00-23:00), the electricity used during this period is flat.

The current positive active valley electricity (is the total amount of positive active electricity consumption accumulated by the meter from the beginning of electricity consumption to the trough period of electricity consumption in this month, and the valley electricity is the electricity consumption during the trough period of metered electricity consumption. For example, the trough period set by dtz341 is (23:.)

00-07:00), the electricity used in this time period is valley electricity, and the unit price of valley electricity is cheaper than the usual unit price of electricity (how much cheaper depends on the local charges).

The current forward reactive power is the total reactive power accumulated by the meter from the beginning of electricity consumption to the positive direction of this month, and the forward reactive power is the amount of electricity generated by the reactive power transmitted by the user using the power grid.

The current total reverse active electricity is the total amount of reverse active electricity accumulated by the meter from the beginning of electricity consumption to the current month. Reverse active electricity is the amount of electricity generated by the user's transmission of electrical energy to the grid. Generally, unless there are special circumstances, this item is 0, and the electricity fee is not calculated.

The current reverse reactive power is the total reactive power accumulated by the meter from the beginning of electricity consumption to the reverse of this month, and the reverse reactive power is the capacitor overcompensation, resulting in reactive power to the power grid, causing the power generated by the power grid, which is not charged with electricity charges.

The total amount of positive active electricity in the previous month (, which is the total amount of positive active electricity accumulated by the meter from the beginning of electricity consumption to the previous month.

According to your description, if you are using a smart meter, it is recommended that you can view the current meter readings through the LCD screen on the meter; A string of numbers on the screen will directly display the integer and decimal of the meter reading, the model of the meter is different, and the data displayed on the LCD screen may be different; You can press the wheel display button next to the screen to switch the display interface and view the data displayed on the LCD screen with the words "Current Total Electricity" or "Current Forward Active Total", which is the cumulative electricity consumption of the current meter.

If you are using a mechanical meter, you can see the cumulative electricity consumption recorded by the meter through the numbers in a row of windows on the dial of the meter; In general, the red window represents the decimal part, which is 1 decimal place; The black window represents the integer part, starting from the far right, with the first digit being the single digit, and so on.

If you need to calculate the actual electricity consumption during a certain electricity consumption period, the electricity consumption = this meter reading - the last meter reading reading, if your meter is equipped with a transformer, you also need to multiply the multiplier of the transformer.

We hope you find ours helpful.

The selection of electricity meters is based on the current specifications. The single-phase meter is selected to calculate the rated current after the total power of the electrical appliances with it, and in the 220V power grid, 1KW has about 5A current.

Power refers to the amount of work done by an object per unit of time, i.e., power is a physical quantity that describes how fast or slow work is done. The amount of work is constant, and the shorter the time, the greater the power value. The formula for finding power is the power work time.

Power indicates the physical quantity of how fast or slow the work is done. The work done per unit of time is called power and is denoted by p. Therefore, the power is equal to the scalar product of the force and the velocity of the point where the object is stressed.

Power representation: power is the physical quantity that represents the speed of the work done by the object, the power in physics p = work j time t, the unit is watt w, the power units we often see on ** are kw, ps, hp, bhp, whpmw, etc., as well as the cv used in Italy.

Here, kilowatt kW is the international standard unit, 1kW = 1000W, and the power of 1000 joules is 1kW when 1 second is done. In daily life, we often refer to power as horsepower, and the unit is horsepower, just like torque is called torque.

In the automotive field, the largest power machine is the engine, the power of the engine is calculated from the torque, and the calculation formula is quite simple: power (w) = 2 torque (nm) speed (rpm) 60, simplified calculation becomes: power (w) torque (nm) speed (rpm).

Meter specifications are generally distinguished by current. Look at the meter, regardless of how many times the meter, such as 10 (80) a, it is 8 times the meter. Commonly used currents are in parentheses, and maximum currents are in parentheses.

In contrast, the power of a single-phase meter is multiplied by the current (220V). Electrical power is calculated by multiplying the current by the voltage. Just find the voltage and current correctly.

Method: Read out the current and voltage, and multiply the two to get the power.

Under normal circumstances, the magnification is not directly displayed on the meter, if your meter has a transformer installed, 1. The electricity customers of Guangdong Power Grid Company can check the magnification of the transformer through the electricity bill electronic bill or check the magnification on the nameplate of your transformer on the spot; You can also follow and bind the "China Southern Power Grid 95598" public platform through WeChat My Electricity Electricity Bill Check and Pay My Electricity Bill Select any electricity bill and click the "View Details" button next to it You can query the meter multiplier in the "Total Electricity" interface.

You can pay attention to the "China Southern Power Grid 95598" public platform, click on the "My Electricity Consumption" personal center, and you can query the user number by binding the mobile phone number reserved by the power supply company or the ID number of the head of the electricity meter.

2. If you are not a customer of Guangdong Power Grid Company, it is recommended that you can learn about the transformer from the owner of the meter.

We hope you find ours helpful.

Method 1: Directly call up the current power data (applicable to the smart meter installed by the electric pure and weak department).

Press the button on the meter to switch the content displayed on the screen until the unit on the right side of the meter screen is only the word "kw", and the number on the screen is the electricity consumption rate, which is measured in kilowatts.

Scheme 2: Calculate the flashing period by pulse indicator (applicable to all electronic energy meters).

First, find the pulse constant of the meter (generally printed on the positive difference hole of the meter, the unit is a data of imp kwh), and then use the stopwatch to measure the interval between two consecutive flashes of the meter pulse indicator (a red light that flashes from time to time) (in seconds), and the average power (in watts) between the two flashes can be calculated by the following formula:

p=3600000 pulse constant The time interval between two flashes.

How to see how much power is left on the meter.

1. If it is a smart meter with an IC card, it will clearly show how much power is left in your home, we only need to adjust one button of it, and this button can control the different functions of the meter. Then you will see that there will be a word in the LCD screen, such as the remaining power, and this smart meter will be displayed directly with Arabic numerals, and you don't need to read it.

2. Some are old-fashioned meters, which will display different digits, including thousands, hundreds, tens, units and decimals, generally speaking, we only need to read the integer part.

3. In addition, we can also query the balance of the electricity bill, if the balance of the electricity bill is relatively low, it will remind you that it is time to charge the fee.
