We know that the capacity of the meter will affect the power consumption of the appliance. The power supply company provides a small-capacity meter for the purpose of charging more. There are two main types of smart meters: one is the incoming line, connected to the power supply, and is responsible for power supply; the other is the outgoing line, connected to the customer's electrical appliances, responsible for transmission measurement. The meter capacity indicates the maximum current value that is allowed to pass during normal operation, and there is no relationship between the power consumption, so the user does not have to worry about this.
Precision shunts are important components in smart meters. The reason why smart meters can accurately measure the measurement depends entirely on the application of precision shunts on smart meters. Moreover, the manufacturer of each smart meter has very high precision requirements for the precision of the transmission shunt, and the shunt that does not have high accuracy cannot correctly feed back the current data.
Therefore, from the precision shunt, we can know the rumors that the smart meter will cause the electricity bill to soar are unrealistic.
