Answer Posted / neeraj pandey
voltage value is the Line to Line Voltage. Line to line
voltage is the voltage between any two phase lines.
In single phase there is one phase and another is earth wire
and voltage between them is 230V approx.
In two phase the line voltage is 1.732 times of the single
phase voltage and the value is 415 V approx.
In three phase system the value of voltage between two
phases are taken which is same as two phase system.
if we take the voltage diff between all three phases it will
be ZERO..
