Single Phase Energy Meter Phasor Diagram

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.

Single phase energy meter phasor diagram.

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. This is the meter that most people will find on their homes. Form 3s meters are typically used for single phase two wire services where the service is so. This article focusses only on its constructional features and its working.

This form is also used for many small businesses as well. 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 name is given to it. To calibrate the given energy meter using a calibrated wattmeter.

Introduction single phase induction meter 3. In diagram i use red coler wire for line phase and black for neutral. Theory operation working 5. Single phase induction type energy meter is also popularly known as watt hour meter.

The phasor diagram of the energy meter is shown in the figure below. Three phase type induction meters. Construction driving system moving system braking syatem and registering system 4. The energy meter has four main parts.

Calibration and testing of single phase energy meter aim. 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. Let v applied voltage i load current. Phasor diagram of single phase induction type energy meter 6.

This meter is most commonly used in a 240v single phase three wire service. Here we are going to discuss the single phase induction type in detail. 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 three phase energy meter is used for measuring the large power consumption.

The construction of the single phase energy meter is shown in the figure below. 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.
