Single phase energy meter phasor diagram.

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. Theory operation working 5. Phasor diagram of single phase induction type energy meter 6.

Below energy meter diagram i shown a single phase kwh meter with incoming supply and out going supply to home collage shop etc. Click here for a form 2s meter wiring diagram. The phasor diagram of the energy meter is shown in the figure below. Introduction single phase induction meter 3.

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. Three phase type induction meters. In diagram i use red coler wire for line phase and black for neutral. This article focusses only on its constructional features and its working.

The construction of the single phase energy meter is shown in the figure below. To calibrate the given energy meter using a calibrated wattmeter. Let v applied voltage i load current. The energy meter has four main parts.

They are the. This form is also used for many small businesses as well. 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. Form 3s meters are typically used for single phase two wire services where the service is so.

This name is given to it. Calibration and testing of single phase energy meter aim. 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 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.
