Single Phase Energy Meter Phasor Diagram

Phasor diagram of single phase induction type energy meter 6.

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. 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 meter is most commonly used in a 240v single phase three wire service. Click here for a form 2s meter wiring diagram.

The phasor diagram of the energy meter is shown in the figure below. They are the. 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. 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.

Here we are going to discuss the single phase induction type in detail. The three phase energy meter is used for measuring the large power consumption. This is the meter that most people will find on their homes. The construction of the single phase energy meter is shown in the figure below.

Let v applied voltage i load current. This form is also used for many small businesses as well. Introduction single phase induction meter 3. Calibration and testing of single phase energy meter aim.

Construction driving system moving system braking syatem and registering system 4. This name is given to it. In diagram i use red coler wire for line phase and black for neutral. Three phase type induction meters.

To calibrate the given energy meter using a calibrated wattmeter. 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. Single phase induction type energy meter is also popularly known as watt hour meter. 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. Theory operation working 5.
