Introduce The Precautions Of Single Phase Electromechanical Kwh Meter

The electric meter is also a very common tool in our daily life, and everyone should be clear about its function.

The electric meter is also a very common tool in our daily life, and everyone should be clear about its function. Now is the era of technology and information, the electricity demand will only increase, so the electric meter has been improved accordingly. Both functions and others have made some progress, and the single phase electromechanical kwh meter have also appeared in succession.

After the single-phase electromechanical kWh meter is installed, close the switch, turn on the light, and the turntable rotates from left to right; after turning off the light, the turntable sometimes still rotates slightly, if it does not exceed a full circle, it is a normal phenomenon. If you continue to rotate after more than a full circle, try to remove the 3 and 4 wires. If they no longer rotate continuously, it means that there is a phenomenon of power overturning on the line. If it continues to rotate, it means that the watt-hour meter is abnormal and needs to be overhauled; there is an AC magnetic field in the watt-hour meter, and it is normal to generate induced current on the metal casing, which will not consume electricity, nor will it affect safety and correct measurement. If the shell is electrified for other reasons, try to eliminate it to ensure safety.

The same is true for the three phase electromechanical kwh meter . Remember the above precautions when using it.
