Single Phase Energy Meter Theory

Induction type single phase energy meter.

Single phase energy meter theory.

Here we discuss the construction and working principle of induction type energy meter. Mechanism of rotation of an aluminum disc which is made to rotate at a speed proportional to the power. Induction type instruments are used for a. Three phase type induction meters.

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. Energy meters are the basic part to measure the power consumption. Here we are going to discuss the single phase induction type in detail. Working of single phase induction type energy meter.

The meter is less expensive and accurate. To understand the structure of watt hour. Mechanism of counting and displaying the amount of energy transferred. The meter which is used for measuring the energy utilises by the electric load is known as the energy meter.

The induction principle find its widest application as an energy meter. 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. It is also known as watt hour 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. It is used everywhere no matter how big or small consumption it is. The basic working of single phase induction type energy meter is only focused on two mechanisms. The number of revolutions is thus proportional to the energy.

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. Circuits in a prescribed period where supply voltage and frequency are constant. This article focusses only on its constructional features and its working.
