Errors, compensations and adjustments for single phase induction energy meters 1 errors: in single phase induction type energy meters the errors may be caused by driving system or braking system. In the induction type single phase energy meter, the flux produced by shunt magnet (pressure or voltage coil current) sh φ lags behind the applied voltage v by almost 90° the flux φ se is produced by the load current i and se φ is in the direction of i (see fig443. The basic working of single phase induction type energy meter is only focused on two mechanisms: 1 mechanism of rotation of an aluminum disc which is made to rotate at a speed proportional to the power. Dt8three phase watt-hour meter application dt8 series three watt-hour meter is a kind of induction type meter which measure energy electric power consumption in rated frequency 50hz and three phase ac electricity net.
Objectives • to understand the basic construction and different components of a single phase induction type energy meter • explain basic principle and development of torque expressions for. Working of single phase induction type energy meter the basic working of single phase induction type energy meter is only focused on two mechanisms: mechanism of rotation of an aluminum disc which is made to rotate at a speed proportional to the power. Single phase induction type energy meters construction of induction type energy meters there are four main parts of the operating mechanism (i) driving system. I think you mean induction motor if you apply dc to an induction motor, it will get hot and not turn induction motors are ac only if you really mean energy meter, they contain an induction motor again dc will damage it.
The operation of induction type energy meter depends on the passage of alternating current through two suitably located coils producing rotating magnetic field which interacts with a metallic disc suspended near to the coils and cause the disc to rotate. The number of revolutions made by the disc depends upon the energy passing through the meter the spindle is geared to the recording mechanism so that electrical energy consumed in the circuit is directly registered in kwh.
The wattmeter is an instrument for measuring the electric power (or the supply rate of electrical energy) in watts of any given circuit electromagnetic wattmeters are used for measurement of utility frequency and audio frequency power other types are required for radio frequency measurements. The principle of working and construction of induction type meter is very simple and easy to understand that's why these are widely used in measuring energy in domestic as well as industrial world. Single-phase induction kilowatt hour meter single phase induction type energy meter is also popularly known as watt-hour meterthis name is given to it this article is only focused about its constructional features and its working.
Induction type meters the principle of working and construction of induction type meter is very simple and easy to understand that's why these are widely used in measuring energy in domestic as well as industrial world. Single phase energy meter the induction type single phase energy meters are universally used for energy measurements in domestic and industrial establishments since they possess some of the very useful features such as . Induction type energy meter ii electrical technology ii unit 3 https: energy meter - working principle and construction - electronic instrumentation and measurement - duration: 33:34. Application type dem071 single phase long life watt-hour meter is a kind of induction type meter which measure active energy electric power consumption in rated frequency 50hz and single phase ac electricity net.
Hence it is the working of induction type energy meter , adjustment of induction type energy meter if you want to know more about the induction type energy meter you must watch this video ← difference between renewable and nonrenewable energy sources. An electricity meter, electric meter, electrical meter, or energy meter is a device that measures the amount of electric energy consumed by a residence, a business, or an electrically powered device. Thus we need an integrating instrument which can measure and record the energy consumed by the load under varying load condition the simplest such instrument is single phase induction type energy meter.
Given below is the picture of single phase induction type meter single phase induction type energy meter consists of four important : systems which are written as follows () a driving system : driving system consists of two electromagnets on which pressure coil and current the diagram. Induction type single phase energy meters these are, by far, the most common form of ac meters met with in every-day domestic and industrial installations these are, by far, the most common form of ac meters met with in every-day domestic and industrial installations.
