What’s wattmeter? What number of sorts of wattmeter | wattmeter circuit diagram | Energy Measurement Strategies | digital watt meter worth | Measurement technique by two watt meters. Measurement technique by three watt meters.
In the present day we’re going to discuss what’s wattmeter and the way it works, why in the present day we are going to talk about about it intimately –
Wattmeter is a tool used to measure electrical energy and it watts of energy I measure in electrodynamic impact is used.
What number of sorts of wattmeter are there?
There are primarily three sorts of wattmeters –
- Dynamometer wattmeter
- induction wattmeter
- Electrostatic wattmeter
Dynamo Wattmeter:- It’s a shifting coil machine, two coils are utilized in it, the strain coil / shifting coil which is made from skinny copper wire, the second present coil which is made from thick enameled copper wire, it’s also known as present coil or stationary coil. |
- scale of this instrument proportionate occurs.
- use this machine AC or DC supply however could be executed equally.
- This instrument can be utilized as a vote meter however not as an ampere meter as a result of a considerable amount of present can’t move by means of the shifting coil of the instrument.
- Altering the frequency might trigger error within the studying of the instrument.

Induction Wattmeter:- On this machine, two electromagnets are used, that are excited by strain coil and present coil. Between the 2 electromagnets, a round disc of aluminum steel is connected to the 2 jeweled buildings at a distance to generate managed torque. Together with this, two hair-comaniyas are utilized.
- Being based mostly on induction precept, this machine can be utilized solely in AC circuits.
- No separate association is made for damping on this machine, as a result of the eddy present generated within the aluminum disc itself routinely generates the eddy present damping pressure.
- Present transformer and potential transformer are used with this instrument to measure voltage in excessive present circuits at excessive voltage.
What are the strategies of energy measurement by wattmeter?
Following are the strategies of energy measurement by wattmeter –
Measurement technique by a wattmeter – A watt meter technique is used to measure energy on a balanced load in all three phases.
Measurement technique by two watt meters – Two watt meter technique is used to measure energy on balanced and unbalanced load in three section system.
Measurement technique by three watt meters – Three watt meter technique is used to measure energy on all section unbalance section in three section system.
