A resident’s home used 1,044 kilowatt hours of electricity in one and a half months. The electricity bill soared to 520 yuan. It was only 200 yuan before. Please analyze the reasons.

I am an electrician. The situation you mentioned can be judged this way

1: The circuit is leaking. If you think there is a problem, you can try this and test the leakage switch at home. Is it good? There is a test button on the leakage switch. If you press the leakage switch, it will trip. Otherwise, the leakage switch is broken. After confirming that the leakage switch is good, the leakage of the circuit to the earth can be eliminated. Now stop all electrical appliances in the house for one hour. The meter should not run at all. If the meter still runs, it means the live wire is leaking to the neutral wire. This leakage switch cannot operate.

2: There is a problem with the electric meter. If you think there is a problem with the electric meter, find a stable load, such as a 750W rice cooker, stop all the electrical appliances in the home and only let the rice cooker boil water. The time is 1000W/750W=1.3 hours, which is about 1 hour and 20 minutes. At this time, the meter should be reading exactly one kilowatt hour. If it is too high, there is something wrong with the meter.

3: Someone steals electricity. This may be from your electric meter when you are not at home. They steal electricity to use for welding and other heavy-loaded things. If this happens, the electricity bill on the meter will be normal next month. If Someone connects your electrical wires in a secluded area of ??your home. This is usually done by your neighbor. If you sometimes deliberately turn off your power switch, and his home also has no power at the same time, then he is stealing electricity.
