What are the types of power factor?

Answer 1

there are 3 types of power factor meter:

1). electrodynamic power factor meter,

2).moving-iron power factor meter and

3). nalder-lipman moving-iron power factor meter.

Answer 2

To my knowledge, there are only two main types, analog and digital. Analog is the old style with four or five round counter with the big horizontal dial that spins. It's electromechanical. Most meters being made now are digital and use C.T.s to measure current usage and display the reading with an L.E.D. readout.

Answer 3

Power factor is simply the ratio of a load's true power to its apparent power. True power is expressed in watts, whereas apparent power is expressed in volt amperes.

Another way of defining power factor is to say that it is the cosine of the phase angle -i.e. the angle by which a load current lags or leads the supply voltage.

To describe the operating principle of a power-factor meter is difficult without referring to a diagram, so I suggest you do a search on the internet for this answer.

Answer 4

A force variable meter is a kind of electrodynamometer development when it is made with two mobile curls set at right edges to one another. The strategy for association of this sort of force component meter, in a 3phase circuit. The two stationary loops, S and S1, are associated in arrangement in Phase B. Curls M and M1 are mounted on a typical shaft, which is allowed to move without limitation or control springs. These loops are associated with their arrangement resistors from Phase B to Phase An and from Phase B to Phase C.
