Difference between load voltage and phase voltage ( sai saikumar jn )

                                                  Hello ,... Engineer's

Interview question for u people

MCQ:- Difference between Load voltage and Phase voltage..?

MUST READ & SHARE

Ans:- Line voltage is the voltage across any two phases of the output of generator.
Phase voltage is the voltage across each phase winding.

If connected in DELTA configuration the line voltage = phase voltage.

If connected in STAR, or WYE configuration, line voltage = 1.732 x phase voltage.

Generators are usually connected in STAR configuration, the star point, or common
connection of the 3 windings being connected to earth, or ground. This provides a
NEUTRAL connection so that 1 phase to neutral will give you the phase voltage, (Line
voltage/1.732). 1.732 being square root of 3.
3 phase power, in Watts, is 1.732 x VL x IL x pf.

Where L = line voltage and line current
and pf = power factor of load, regardless of how connected.
