Types of Energy Meter
Generally some types of energy meter are as follows:
- Single Phase Energy Meter
- Three Phase Energy Meter
- Analogue Energy Meter
- Digital Electric Energy Meter
- Time of use Energy Meter
Single Phase Energy Meter
Single phase energy meter is used for home appliances. The single phase energy meter is directly connected between the line and load. It consists of two electromagnets one is the shunt magnet and other is the series magnet and in between these two magnets we are having the aluminium disk. So this aluminium disk is rotating in the magnetic field. The speed of this disk is proportional to the part which is consumed by the appliance. Read my article on the Electrical House wiring, in this article you will learn how energy meter is connected, and also explains the complete house wiring.
Three Phase Energy Meter
Three phase energy meter is used for commercial or industrial application. As in the industries we have huge amount of current so to protect it we will use current transformer. It will step down the current to isolate energy meters from high current. The three phase energy meters have three phase wires and one neutral wire. The output three wires go to the main db. One unit means 1000 watt hour.
Analogue Energy Meter
Also known as electromechanical meter, these are among the oldest meter in Indian history. They do not have a display or connectivity facility. These meters read the electricity and display it on circular scales. The operator reads the electricity meter on the scale and analyses the total electricity consumed.
Digital Energy Meter
These meters offer easier readings than analogue electric meters. Besides, they provide an LED or LCD display and have a connectivity feature. The operators do not need to calculate the readings on the scale as the LED or LCD screen provides an accurate reading.
Time-of-Use Energy Meter
This is the third type and can either be digital or analogue. The primary difference is that it is for people who register for the time-of-use plan. In this plan, the electricity is charged considering the peak and off-hours. Two separate meters are used for this purpose, one for calculating the electricity during peak hours and the other for off-peak hours.
Energy Meter
Energy meters play a crucial role in measuring and monitoring electrical energy consumption, enabling fair billing, promoting energy efficiency, and supporting the management of power distribution networks. These meters come in different forms, including analog, digital, smart meters, and advanced metering infrastructure (AMI). There are various types of energy meters, which have several functions. It is used for household or domestic purposes for measuring electricity bills. In this article, we will go through what is energy meter?, construction with its operations, Then we will go through its types and finally, we will conclude our article with its Advantages, Disadvantages, and characteristics.
