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.
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 is the meter that most people will find on their homes.
The phasor diagram of the energy meter is shown in the figure below.
Form 3s meters are typically used for single phase two wire services where the service is so.
Introduction single phase induction meter 3.
Phasor diagram of single phase induction type energy meter 6.
Calibration and testing of single phase energy meter aim.
Click here for a form 2s meter wiring diagram.
This article focusses only on its constructional features and its working.
In diagram i use red coler wire for line phase and black for neutral.
Construction driving system moving system braking syatem and registering system 4.
The energy meter has four main parts.
Let v applied voltage i load current.
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.
This name is given to it.
This form is also used for many small businesses as well.
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 induction type energy meter is also popularly known as watt hour meter.
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 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.
They are the.
To calibrate the given energy meter using a calibrated wattmeter.
Three phase type induction meters.
Here we are going to discuss the single phase induction type in detail.
