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.

why we cant use AC supply products in DC supply?
