How to check the electric meter yourself.
Electronic-mechanical electricity meter counts electricity in 3 ways
1. By means of a digital dial with an accuracy of a hundredth of a kWh
2. Flashing LED. 3200 pulses per 1 kWh.
Link to this video. This is the meter constant
3. Clicking. 200 times per 1 kWh. This is the gear ratio of the counter.
Electricity consumption is equal to power multiplied by time. The consumed electricity is measured in kWh.
You can check the electricity meter with a 100W light bulb or a 1000W electric stove.
We count the flashing of the LED, the clicking of the counter and the movement of the last wheel of the dial.
An electronic meter is checked in the same way as an electronic-mechanical electric meter, only it has an electronic display instead of a dial. we check the electronic meter in the same way as the electronic_mechanical one.
The induction counter has a similar dial. as well as an electronic-mechanical counter. Instead of flashing the LED, it counts the revolutions of the disk. The number of revolutions per kWh is the constant of the electricity meter. the mechanical counter is checked according to the same formulas as the electronic-mechanical one.
In a three-phase meter, each phase is checked separately. a three-phase meter, in fact, these are 3 single-phase meters, united by a common housing and counting mechanism.
In electric meters with 2 current sensors, special attention should be paid so that the LEDs "Reverse", "Earth", "Difference between phase and zero currents" do not light up. If they light up, then the meter is not connected correctly, which leads to increased electricity readings.
Check the electric meter for self-propelled. Otherwise, you pay for electricity that you did not consume. The procedure for checking the electric meter for self-propelled
1 Do not turn off the input machine
2 Turn off the machines after the electricity meter
3 Record the electricity meter reading
4 Leave it like this for a long time
5 Compare old readings with new ones
6 If they differ, the electric meter is self-propelled.
I do not recommend repairing the electric meter. It is better to replace the electric meter. It will come out cheaper.
