The reading of three-phase four-wire watt-hour meter can be directly seen in the reading area of its watt-hour meter. When confirming the actual power consumption, it is necessary to calculate the actual power consumption according to whether the incoming line passes through the transformer. If there is a transformer, you need to multiply the reading by the multiplier of the transformer to calculate the actual power consumption.

The main type of smart meters is IC card meters. The user pays money to the power supply department with an IC card, and the power supply department writes the purchase amount into the IC card with the power sales management machine. Users can turn on the power by swiping the contactless IC card in the induction area with the IC card. After the power supply, they will leave Kolor. When the remaining power of the meter is equal to the alarm power, turn off the power supply and give an alarm (or buzzer alarm). At this time, the user can restore power supply by swiping the card in the induction area; When the remaining power is zero, the switch is automatically turned off.
