Single Phase Energy Meter Phasor Diagram

This is the meter that most people will find on their homes.

Single phase energy meter phasor diagram.

Below energy meter diagram i shown a single phase kwh meter with incoming supply and out going supply to home collage shop etc. Click here for a form 2s meter wiring diagram. Here we are going to discuss the single phase induction type in detail. A complete sine wave can be constructed by a single vector rotating at an angular velocity of ω 2πƒ where ƒ is the frequency of the waveform.

The construction of the single phase energy meter is shown in the figure below. In the above diagram i shown an utility pole form which i get supply to kilowatt hour e meter and after that i get supply form energy meter. The magnetic field produced by series magnetic in phase with the line current and magnetic field produced by shunt magnet is in quadrature with the applied voltage thus a phase difference exists between the fluxes produce by the two. Form 3s meters are typically used for single phase two wire services where the service is so.

The phase of an alternating quantity at any instant in time can be represented by a phasor diagram so phasor diagrams can be thought of as functions of time. This form is also used for many small businesses as well. Calibration and testing of single phase energy meter aim. Let v applied voltage i load current.

This meter is most commonly used in a 240v single phase three wire service. This article focusses only on its constructional features and its working. S no equipment range type quantity 1 variac single phase 10 a ac 2 voltmeter 300 v ac 3 ammeter 0 10a ac 4 rheostat ac 5 wattmeter lpf ac 6 single phase energy meter 10a ac theory. Theory operation working 5.

This name is given to it. Introduction single phase induction meter 3. The energy meter has four main parts. When the energy meter is connected in circuit the current coil carries the load current and pressure coil carries the current proportional to the supply voltage.

The phasor diagram of the energy meter is shown in the figure below. Phasor diagram of single phase induction type energy meter 6. Three phase type induction meters. The three phase energy meter is used for measuring the large power consumption.

To calibrate the given energy meter using a calibrated wattmeter. Single phase induction type energy meter is also popularly known as watt hour meter.
