Single Phase Energy Meter Phasor Diagram

Three phase type induction meters.

Single phase energy meter phasor diagram.

Calibration and testing of single phase energy meter aim. This meter is most commonly used in a 240v single phase three wire service. This name is given to it. The construction of the single phase energy meter is shown in the figure below.

Click here for a form 2s meter wiring diagram. They are the. Introduction single phase induction meter 3. Below energy meter diagram i shown a single phase kwh meter with incoming supply and out going supply to home collage shop etc.

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. 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. 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.

To calibrate the given energy meter using a calibrated wattmeter. The three phase energy meter is used for measuring the large power consumption. Form 3s meters are typically used for single phase two wire services where the service is so. This form is also used for many small businesses as well.

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. This article focusses only on its constructional features and its working. Single phase induction type energy meter is also popularly known as watt hour meter.

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. The energy meter has four main parts. This is the meter that most people will find on their homes.

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. Theory operation working 5.
