Energy Meter or Watt-Hour Meter is an electrical instrument that measures the amount of electrical energy used by the consumers. Utilities are one of the electrical departments, which install these instruments at every place like homes, industries, organizations, commercial buildings to charge for the electricity consumption by loads such as lights, fans, refrigerator, and other home appliances.

The basic unit of power in watts and it is measured by using a Din Rail Energy Meter. One thousand watts make one kilowatt. If one uses one kilowatt in one-hour duration, one unit of energy gets consumed. So energy meters measure the rapid voltage and currents, calculate their product and give instantaneous power. This power is integrated over a time interval, which gives the energy utilized over that time period.

Types of Energy Meters

The energy meters are classified into two basic categories, such as:

Electromechanical Type Induction Meter

Electronic Energy Meter

The electricity supply connection may be either single phase or three phase depending on the supply utilized by the domestic or commercial installations. Particularly in this article, we are going to study about the working principles of single-phase electromechanical induction type energy meter and also about three-phase electronic energy meter from the explanation of two basic energy meters as described below.

Single Phase Electromechanical Induction Energy Meter

It is a well-known and most common type of age-old Smart Energy Meter. It comprises a rotating aluminum disc placed on a spindle between two electromagnets. The rotation speed of the disc is proportional to the power, and this power is integrated by the use of gear trains and counter mechanisms. It is made of two silicon steel laminated electromagnets: shunt and series magnets.
