Street Light Pole Top Box "specialty is our goal"

The manufacturer of the Street Light Pole Top Box will share with you the use of the electric energy meter and the precautions for the use of the electric energy meter. Under the condition of low voltage (no more than 500 volts) and small current (tens of AMPS), the electric energy meter can be directly connected to the measuring circuit. In the case of high voltage or current, the electric energy meter cannot be directly connected to the line, and the use of voltage transformer and current transformer is required. For direct access line watt hour meter, select appropriate specifications according to load voltage and current. The rated voltage and rated watt hour meter current are equal to or slightly greater than the load voltage or current. In addition, the power consumption of the load at 10% of the rated value of the electric energy meter, otherwise the measurement is inaccurate. Sometimes it doesn't rotate at all. Therefore, the instrument cannot be too large. If it is too small, it is easy to burn the electric energy meter
