Single Phase Energy Meter Phasor Diagram

Here we are going to discuss the single phase induction type in detail.

Single phase energy meter phasor diagram.

Construction driving system moving system braking syatem and registering system 4. Calibration and testing of single phase energy meter aim. This form is also used for many small businesses as well. To calibrate the given energy meter using a calibrated wattmeter.

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. The construction of the single phase energy meter is shown in the figure below. The energy meter has four main parts. Below energy meter diagram i shown a single phase kwh meter with incoming supply and out going supply to home collage shop etc.

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

In diagram i use red coler wire for line phase and black for neutral. The phasor diagram of the energy meter is shown in the figure below. Theory operation working 5. 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. They are the. Click here for a form 2s meter wiring diagram. 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 three phase energy meter is used for measuring the large power consumption. This meter is most commonly used in a 240v single phase three wire service. 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.

This name is given to it. Introduction single phase induction meter 3.
