An electricity meter, electric meter, electrical meter, energy meter, or kilowatt-hour meter is a device that measures the amount of electric energy consumed by a residence, a business, or an electrically powered device. Electric meter or energy meter measures the total power consumed over a time interval. Electric utilities use electric meters installed at customers' premises for billing and monitoring purposes. They are typically calibrated in billing units, the most common one being the kilowatt hour (kWh). They are usually read once each billing period. When energy savings during certain periods are desired, some meters may measure demand, the maximum use of power in some interval. "Time of day" metering allows electric rates to be changed during a day, to record usage during peak high-cost periods and off-peak, lower-cost, periods. Also, in some areas meters have relays for demand response load shedding during peak load periods.

(1) Electric energy meters can be divided into DC electric energy meters and AC electric energy meters according to the circuits they use. AC electric energy meters can be divided into single phase energy meters, three-phase three-wire electric energy meters and three-phase four-wire A relay is an electrically operated switch. It consists of a set of input terminals for a single or multiple control signals, and a set of operatingA printed circuit board (PCB) is a laminated sandwich structure of conductive and insulating layers.

IPS, TFT, and SLCD are all subclasses of LCD. Its working principle is that under the action of the electric field, the alignment direction of the liquid crystal molecules is changed,
