In case of 3Phase Supply,
Voltage R-Earth/Neutral - 220
Y-Earth/Neutral - 220
Z-Earth/Neutral - 220
Total is -> 660Volts
Then Why it is said that 3Phase supply is 440

Answer / sachin mahangade
this voltage measure in R-Y 440v Y-B 440v RB-440 v so this
said that 3 phase R-Y-B supply is 440 v

Answer / jmdt
we are calculating in phase to pase oly , so r-y, y-b, b-r
is 440 volt

Answer / zubair
in three phase supply there are three phases (here R, y,
and z) and only one neutral.
the voltage between any one phase and neutral is 220.
and the voltage between remaining two phases is 440.hence
the 3 phase supply is 440

Answer / padmavathi
If we measure R-Earth/ Neutral that is 1 PH. 3 Phase, 440V
means we have to measure Phase - Phase i.e. R-Y, Y-B, R-B

Answer / vinoth
the vole meter have 2 terminals only.... then how can we
mesure in 3 phase voltage... only chance mesure in 2 phases
only the 2 phase voltage 440

Answer / n
220 Multiply by root three is equal to 281.4 volts. for 440
volts single phase voltage up to 254 volts.

What is MSL designation of a motor and same may be provided in details.
when we r using 3.5 cable for a bldg. and put laod on each phase using the neutral and neutral is the return paht for the phase so the current of the neutral must be Ir+Ib+iY (return).But the size of the netural is .5 as comper to the phase.
