Is it possible to measure the power factor of the balanced?
Of the 'balanced' what?
Is it possible to measure power factor of the balanced three-phase load by two-wattmeter method?
yes.
Is it possible for generators having different power factor to work together?
yes, it is possible. in fact in power systems all the generators do not run with same power factor.
What mean power factor 0.26 lead?
When looking at power factor, it is the ratio of watts (true power) to VA. The power factor is how we measure power systems. A person with a low power factor like .26 will have a higher electricity bill.
Why dynamo meter not use for measure power factor?
Because a dynamometer is used to measure the mechanical power output of a motor or engine. There are ways of measuring the power factor directly, for example use a plug-in power and energy monitor.
What is equivalent of MW to Kva?
VA is the measure of Complex Power in a system which includes Real power(Watts, KW, MW) and Reactive power.Direct answer to your question :VA = Power Factor * Real Power (W Or KW Or MW)
Can power factor greater than 1?
not possible. power factor is an cosine angle between current and voltage...
What is power factor of resistor?
A resistor doesn't have a power factor. However, if a circuit is pure resistance in nature the power factor will be one when a voltage is applied and a current flows in the circuit. The power factor is a measure of the relative phases of the current and voltage in a circuit.
Why should the power factor of a power system be high?

Is it possible to transmit power with leading power factor?
The power factor depends on the properties of the load, and if any power factor correction is done it has to happen at the load, so that the current in the transmission lines is reduced. Correcting the power factor at the sending end fails to address the problem.
Why dc supply is a unity power factor?
Power factor is a measure of the ratio between the "True Power" and the "Apparent Power" of a system. THe variation from unity arises from the effect of certain components (namely capacitors and inductors) on an AC waveform, causing a phase shift between the current and the voltage. As a DC supply does not suffer from these reactive losses there is no reactive power and the current and voltage are always "in phase". With a phase angle of 0 degrees, the power factor is the cosine of the angle... cos 0 = 1 therefore unity power factor!
