This paragraph] active energy meter and reactive energy meter.

Active energy meter.

Electrical energy can be converted into various types of energy. For example, it is converted into heat energy through electric furnaces, mechanical energy through motors, and light energy through electric lamps. The electrical energy consumed in these conversions is active energy. The meter that records this electrical energy is an active energy meter.

Reactive energy meter.

The principle of electrical engineering tells us that some electrical devices must first establish a conversion environment when doing energy conversion, such as: motors, transformers, etc., must first establish a magnetic field to do energy conversion, and some electrical devices need to establish an electric field before energy conversion. Whereas, the electrical energy required to establish the magnetic and electric fields is reactive energy.

The meter that records this energy is a reactive energy meter. Reactive energy does not consume energy in the electrical device itself, but it will generate reactive current in the electrical circuit, and a certain loss will be generated in the current ** circuit. Reactive energy meters are specially designed to record this loss, and generally only larger units are installed with this type of meter.

When there is electricity and when there is a load, the dial of the meter is turned to the right.

During the operation of the meter, the remaining power and total power consumption in the meter are displayed in turn every 30 seconds, when the small indicator light in the upper left corner of the display is lit, the total electricity consumption is displayed, and when the small indicator light in the lower left corner of the display is lit, the remaining power is displayed.

The total electricity consumption is displayed in two segments: the first segment displays the values of 100,000, 10,000, and 100, the second segment displays the values of ten, single and decimal places, and the remaining electricity is displayed in two segments, the first segment displays the values of thousands and hundreds, and then displays the values of 10 digits, single digits and decimal places.

There is an electronic watt-hour meter that turns on for a while and dims when there is electricity, and if you cut off all the power when it is on, that indicator will stay on.

But now most of them are in the electricity when a while to flash it, a degree of electricity 3000 flash, not necessarily flash when the electricity must be in the electricity, the more electrical appliances flashed, the faster the flash, long dark or bright must not be working with electrical appliances.

Energy meter (watt-hour meter): A meter that measures the amount of electrical energy consumed by an electrical appliance. 1 kWh 1 kWh 1000 watts 3600 seconds = joules.

For example, how many hours can 1 kWh of electricity make two "220V, 40W" lights work?

Solution t w p 1 kWh (2 40 watts) 1000 watt hours 80 watts = hours.

The speed of the electric energy meter is related to the power of the electric appliance, the more powerful the electrical appliance is working, the faster the disc of the electric energy meter will rotate.

Significance of important parameters:

1. "220V" - means that the energy meter should be used in the circuit of 220V.

2. "10 (20A)" - means that the calibration current of this ruler-type Youneng meter is 10A, and the rated maximum current is 20A (where 20A is not the maximum current allowed in a short period of time but the rated maximum current).

3. "50Hz" - means that it is used in 50Hz AC circuit.

4. "600revs kw·h" - means that for every 1 kilowatt-hour of electrical energy consumed, the turntable on the energy meter Linghuai turns 600 times.

It is calculated according to the number of revolutions rotated by the turntable of the energy meter. If the energy meter is marked with "600revs kw·h", when the turntable turns n times, the energy consumed is w=nr 600r kw·h=n 600.

Electric energy meterThe electric energy meter is a meter used to measure electric energy, also known as an energy meter, a fire meter, and a kilowatt-hour meter, which refers to a meter that measures various electrical quantities. When using an energy meter, it should be noted that in the case of low voltage (no more than 500 volts) and small current (tens of amps), the energy meter can be directly connected to the circuit for measurement. In the case of high voltage or high current, the electric energy meter cannot be directly connected to the line, and needs to be used with a voltage transformer or current transformer.
