Single Phase Energy Meter Theory

Here we discuss the construction and working principle of induction type energy meter.

Single phase energy meter theory.

Three phase energy meter definition. It is used everywhere no matter how big or small consumption it is. Mechanism of counting and displaying the amount of energy transferred. Induction type energy meter used invariably to measure the energy consumed in any a c.

This name is given to it. Energy meters are the basic part to measure the power consumption. Three phase type induction meters. Single phase induction type energy meter is also popularly known as watt hour meter.

On a single phase ac supply the electromechanical induction meter operates through electromagnetic induction by counting the revolutions of a non magnetic but electrically conductive metal disc which is made to rotate at a speed proportional to the power passing through the meter. The induction principle find its widest application as an energy meter. Working of single phase induction type energy meter. The meter which is used for measuring the energy utilises by the electric load is known as the energy meter.

Circuits in a prescribed period where supply voltage and frequency are constant. The meter is less expensive and accurate. The meter which is used for measuring the power of three phase supply is known as the three phase energy meter the three phase meter is constructed by connecting the two single phase meter through the shaft. Induction type single phase energy meter.

Here we are going to discuss the single phase induction type in detail. The total energy is the sum of the reading of both the elements. It is also known as watt hour meter. The basic working of single phase induction type energy meter is only focused on two mechanisms.

This article focusses only on its constructional features and its working. The number of revolutions is thus proportional to the energy. Mechanism of rotation of an aluminum disc which is made to rotate at a speed proportional to the power.
