Single Phase Energy Meter Phasor Diagram

This name is given to it.

Single phase energy meter phasor diagram.

They are the. This article focusses only on its constructional features and its working. To calibrate the given energy meter using a calibrated wattmeter. The construction of the single phase energy meter is shown in the figure below.

This meter is most commonly used in a 240v single phase three wire service. Phasor diagram of single phase induction type energy meter 6. 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.

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. Three phase type induction meters. Let v applied voltage i load current.

Single phase induction type energy meter is also popularly known as watt hour meter. Construction driving system moving system braking syatem and registering system 4. 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. Form 3s meters are typically used for single phase two wire services where the service is so.

Theory operation working 5. 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 phasor diagram of the energy meter is shown in the figure below. The three phase energy meter is used for measuring the large power consumption.

Below energy meter diagram i shown a single phase kwh meter with incoming supply and out going supply to home collage shop etc. In diagram i use red coler wire for line phase and black for neutral. 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. This form is also used for many small businesses as well.

Introduction single phase induction meter 3. The energy meter has four main parts.
