What is motor power factor?
Power factor is the ratio of apparent versus true power. It depends on the phase angle between voltage and current, and is the cosine of that phase angle. This occurs because a motor is an inductive (reactive) load, constituting a stored energy device. In an inductor, current lags voltage. In a capacitor, current leads voltage.

Is transmission voltage a phase to phase voltage or a phase to ground voltage?
Phase to Phase voltage Correction to the above answer: There is no such thing as a 'phase-to-phase' or 'phase-to-ground' voltage. The correct terms are 'line-to-line' (or 'line voltage') and 'line-to-ground' (or 'phase voltage'). Transmission-line voltages are line-to-line (or 'line') voltages.

If in the three phase connection phase to phase voltage is 400v what will be the phase neutral voltage?
The formula to use is, phase voltage /1.73 = phase to neutral (ground) voltage. Comment There is no such thing as a 'phase to phase', or 'phase to neutral' voltage.

Why capacitor improve the power factor?
A capacitor draws a leading current which is in anti-phase to the current drawn by the inductive component of the load, and the resulting load current will therefore be closer to being in phase with the supply voltage, thus reducing the phase angle or improving the power factor (cosine of the phase angle).

How do you calculate the voltage between a phase and ground?
There is no such thing as a 'phase-to-phase' voltage. The correct term is 'line-to-line' voltage or 'line voltage'. For a star (wye) connected system, the line voltage is 1.732 times the phase voltage, where the phase voltage is measured between any line and neutral.

How many phase to phase voltage in 440 lines?
Let's get the terminology correct. A 'phase voltage' is measured across a phase, whereas a line voltage is measured between two lines. So there is no such thing as a 'phase to phase' voltage -it's a line to line voltage (hence the term 'line voltage').

What is a line to line voltage?
In a 3 phase system, the voltage measured between any two phase is called line to line voltage. And the voltage measured between line to neutral is called phase to neutral (line to neutral) voltage. Answer There is no such thing as a 'phase-to-phase' or a 'phase-to-neutral' voltage. The correct terms are 'line-to-line' and 'line-to-neutral'. The voltage between any two line conductors is called a line voltage. In a three-phase, three-wire, system, the line voltage...
