What is the reason for the total burning of electric meters?

1. Some workers were careless when installing the electric energy meter, and did not tighten the wiring screws or carry out copper-aluminum transition treatment, resulting in poor contact or oxidation, burning out the junction box and disconnecting the current coil.

2. The voltage coil is burnt out due to natural disasters and lightning strikes. Note: When installing the electric energy meter, choose the installation location reasonably to avoid lightning strike.

3. There are many inferior watt-hour meters on the market at present. There are quality problems in the selection of components and coils, the treatment of solder joints and the assembly process. They are not produced and tested according to national standards, and it is even more impossible to make promises on quality and after-sales service. Using this inferior watt-hour meter is easy to burn down and cause accidents.

4. In this case, due to the aging of the line, rats bit the wire, and the socket and switch were not carefully repaired at home, and the watt-hour meter burned badly.

5. In rural areas where the land is vast and the population is sparse and scattered, the line from the transformer to the user is far away, and the voltage drop is large. Some subscriber line voltages are only l80V, not to mention the power supply voltage of 380V.

6. Due to improper operation, the power cord is mistakenly connected to the lighting line, resulting in the burning of the voltage coil of the watt-hour meter.
