Introduction To Electrical Fittings: What Is Electrical Quantity?

Energy power meter Introduction What is electricity?
Electricity refers to the amount of electrical energy required by electrical equipment. The unit of electricity is kilowatt-hour (kWh). Electricity is also divided into active electricity and reactive electricity. The unit of reactive electricity is kilowatt-hour (kvarh).
The power load must have a maximum value within a certain time interval, which is called the maximum load. The average value of the power load within a certain period of time is called the average load. The ratio of the average active load to the maximum load is called the load rate. Adjusting the load and increasing the load rate not only makes the power consumption of the power unit economically reasonable, but also creates conditions for the safe and economic operation of the entire power grid.
