Why you use low power factor wattmeter on primary and unity power factor on secondary side of transformer?
There is no such thing as a 'low power-factor' wattmeter. A wattmeter always reads true power, regardless of the load's power factor.
Is it possible to measure power factor of the balanced three-phase load by two-wattmeter method?
yes.
What is effect of power factor on the readings of wattmeter?
If you are asking whether power-factor improvement has any effect on a wattmeter reading, then the answer is no, it doesn't. Improving the power factor of a load has absolutely no effect on the power of the load, but it can act to reduce the value of the load current.
Why you use upf wattmeter for short circuit test on load test on single phase transformer?
If, by 'upf', you mean 'unity power factor', then allwattmeters measure the in-phase component of the load current, so the term is quiet unnecessary.A short-circuit test is used to determine the (true) power loss in the transformer, which is exactly what a wattmeter measures
What is difference between lpf and upf wattmeters?
LPF wattmeter is used for measuring power in highly inductive circuits & UPF wattmeter is used for measure power in resistance circuit in which the power factor ranges from 0.5 to unity. Answer is given by :Er. M KUMAR YADAV
Why you use low power factor wattmeter on primary and unity power factor on secondary side of transformer?
There is no such thing as a 'low power-factor' wattmeter. A wattmeter always reads true power, regardless of the load's power factor.
State the meaning of multiplying factor of wattmeter and with suitable example explain how it is determined?
watt meter is constructed such that it read only power on a single scale. Only single scale will available to read the measured power. In order to take the accurate reading just we measure the reading and we will multiple along with factor called multiplication factor. That's depends on on which voltage knob we connected and also the current. Multiplication factor can be determined by: Multiplication factor =(voltage range*current range*pf)/Max scale deflection.
What does upf stands in upf wattmeter?
Unity Power Factor.
What does factor strings mean?
Factor strings are multiplication sentences. 3 x 3 is a factor string for 9.
What is low power factor watt meter?
A wattmeter reads the true power of a load, regardless of its power factor.
What is factoring multiplication?
Factor multiplication is the process of multiplying prime factors. The product of factor multiplication is the number that the prime factors are multipilicands of.
How is the power factor of an Electrodynamometer type wattmeter improved?
Power Factor of an electrodynamometer can be improved by connecting a large resistor in series with the current coil.
What is the meaning of da newton?
The Prefix 'da' is a multiplication factor. It stands for deca and In this case is a multiplication factor of 10.
Is it possible to measure power factor of the balanced three-phase load by two-wattmeter method?
yes.
What does factor mean when it's multiplication?
Two numbers that multiply to create another number are factors of that number.
What is the multiplication factor in watt meter?
wattmeter is constructed such that it read only power on a single scale. Only single scale will avilable to read the measured power. In order to take the acuurate reading just we measure the reading and we will multiple along with factor called multificaion factor. That's depends on on which voltage knob we connected and also the current. Multification factor can be dtermind by: Multification factor =(voltage range*current range*pf)/Max scale deflection...
What is thew answer to multiplication problem?
the multiplication of two numbers is called a factor the answer to a multiplication problem is called a product
