1 metering problems of electric meters. It means that the internal metering components of the electric meter are damaged by human or self-failure, resulting in over-counting.

Someone connected the electricity behind the meter. That is to say, your billiard room used to use an electricity meter, but someone connected the electricity behind your electricity meter, and then all the electricity was measured on your electricity meter, which led to an increase in electricity.

The solution is to cut off the power supply of the electricity meter, that is, turn off the circuit breaker or air switch on the incoming side of the electricity meter to see if any other merchants have power outages. Under normal circumstances, only your billiard room should be dead. If other merchants lose power, it is likely that your electricity meter is receiving power.

There is something wrong with the wiring behind the meter, which means there is something wrong with the wiring in your billiard hall, which leads to the meter using more electricity.

The solution is to turn off all the appliances in the billiard hall and see if the electric meter can still be used. If it's still spinning, there's a problem.
