Single Phase Energy Meter Theory

The total energy is the sum of the reading of both the elements.

Single phase energy meter theory.

The meter is less expensive and accurate. The meter which is used for measuring the energy utilises by the electric load is known as the energy meter. Induction type instruments are used for a. Working of single phase induction type energy meter.

Circuits in a prescribed period where supply voltage and frequency are constant. Mechanism of counting and displaying the amount of energy transferred. Three phase energy meter definition. To understand the structure of watt hour.

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. Induction type energy meter used invariably to measure the energy consumed in any a c. Single phase induction type energy meter is also popularly known as watt hour meter. Energy meters are the basic part to measure the power consumption.

It is used everywhere no matter how big or small consumption it is. This article focusses only on its constructional features and its working. Here we are going to discuss the single phase induction type in detail. The energy is the total power consumed and utilised by the load at a particular interval of time it is used in domestic and industrial ac circuit for measuring the power consumption.

The number of revolutions is thus proportional to the energy. Three phase type induction meters. 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. Mechanism of rotation of an aluminum disc which is made to rotate at a speed proportional to the power.

The induction principle find its widest application as an energy meter. Induction type single phase energy meter. It is also known as watt hour meter.
