Single phase energy meter phasor diagram.

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. 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 form is also used for many small businesses as well. The energy meter has four main parts.

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. To calibrate the given energy meter using a calibrated wattmeter. Calibration and testing of single phase energy meter aim. Theory operation working 5.

Form 3s meters are typically used for single phase two wire services where the service is so. Phasor diagram of single phase induction type energy meter 6. 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. Below energy meter diagram i shown a single phase kwh meter with incoming supply and out going supply to home collage shop etc.

This article focusses only on its constructional features and its working. Here we are going to discuss the single phase induction type in detail. Three phase type induction meters. The construction of the single phase energy meter is shown in the figure below.

In diagram i use red coler wire for line phase and black for neutral. 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. Single phase induction type energy meter is also popularly known as watt hour meter. They are the.

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. The three phase energy meter is used for measuring the large power consumption. Introduction single phase induction meter 3.

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