What is the working principle of 3-phase energy meter?
The principle of working of a 3-phase energy meter is similar to the single-phase energy meter. When the load is connected to the meter both the pressure coil and the current coil of the two elements mounted on the shunt and series magnet produces magnetic flux.
What is the working principle of energy meter?
Working Principle of Energy Meter The basic principle of induction energy meter is electromagnetic induction. A thin disc of aluminium (or copper) is pivoted between the two Shunt and Series magnets and cuts the fluxes of both the magnets (Fig. 1). Hence two eddy currents are induced in the disc.
What is the principle of digital energy meter?
This type of meter operates by counting the revolutions of a metal disc that rotates at a speed proportional to the power drawn through the main fuse box. Nearby coils spin the disc by inducing eddy currents and a force proportional to the instantaneous current and voltage.
How many types of 3-phase energy meter are there?
Basically three types of energy meters are present. It consists of rotating aluminum disc mounted on a spindle between two electro magnets. Speed of rotation of disc is proportional to the power and this power is integrated by the use of counter mechanism and gear trains.
What is a three-phase meter?
What is a 3-Phase electric meter? The 3-phase electric meter is used for measuring the power of three-phase electrical supply, most commonly for commercial use.
What is the principle of single-phase 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. Mechanism of counting and displaying the amount of energy transferred.
How do you install a 3 phase energy meter?
Installation of 3 Phase kWh Energy Meter
- R = RED Phase / Live Wire from the source supply voltage.
- Y = YELLOW Phase / Live Wire from the source supply voltage.
- B = BLUE Phase / Live Wire from the source supply voltage.
- Line or IN = Incoming Phase / live or Neutral from the source supply voltage.
What is energy meter explain working of single-phase induction type energy meter?
What is the working principle of wattmeter and energy meter?
The energy meter work on the principle of conversion of electrical energy into mechanical energy. Whereas the wattmeter works on the principle that the force acts on the current-carrying conductor when it is placed in an electromagnetic field.
What is phase meter and its types?
Single phase energy meter is used for home appliances. The single phase energy meter is directly connected between the line and load. It consists of two electromagnets one is the shunt magnet and other is the series magnet and in between these two magnets we are having the aluminium disk.
