Explanation of common data parameters of meter boxes

The meter box is a device used to measure, record and monitor the use of electrical energy. Common data parameters include current (unit: Ampere), voltage (unit: Volt), power (unit: Watt), power factor, frequency (unit: Hertz) wait. Current represents the number of electrons flowing in a circuit, voltage represents the force behind the current, and power is the rate at which electrical energy is converted into other forms of energy. Power factor is the phase relationship between current and voltage, which represents the effective utilization of electrical energy. Frequency represents the periodicity of the current, usually 50 Hz. In addition, the meter box may also display the amount of electrical energy used (unit: kilowatt hours), which is used to settle electricity bills. These parameters are presented through digital or analog displays to help users monitor power usage, rationally arrange power usage, and improve energy efficiency. Meter boxes play an important role in power management, ensuring stable operation of the power system and rational use of electrical energy.
