Answer / kamal

the voltage between two phases is called phase voltage
and the voltage between phase neutral is called line voltage

Answer / ramit saluja

both are actually same....

v(line)= v(R or Y or B) - v(neutral) = 220 v
now,
v(R) - v(Y) = [v(R)-v(N)]-[v(Y)-v(N)]
but both the phase are separated by a phase angle of 120 deg
so acc. to vector addition
v(R)-V(Y)= [(220)^2 + (220)^2 + 2*220*220*.5]^.5 = 220*1.732
= 381.04
and not 440...plz think bout it
i hope u r agree....thnx

Answer / unknown

Phase to Phase Volatge is referred to as Phase Voltage and
the formula is ......... Vphase = Root 3 * 240V = 415V

whereas

Line to Neutral is simply called Line Voltage and it is
Vline = 240V

Answer / devang

Phase to phase voltage
means.phase to naural
voltage 240v and line to line
means phase to phase 440v.

Answer / jk

If so, how the difference noted in 440V & 415V?

Answer / sankar maiti b.tech ee w.b

Q. what is phase to phase voltage? what is line to line
voltage
Answer:


phase to phaes voltage 440v
line to line voltage is 220v

Answer / nagarjuna

phase to phase voltage means ,the voltage b\w the phases(r,y,b).
line to line voltage means the the voltage b\w line and neutral.
Vph=Vl/1.732

Answer / sankar maiti b.tech ee (

phase voltage 440v and line voltage 220v

Answer / ravichikmagalur

phase to phase 440

line voltage 220

Answer / satish

there is a standar for three phase wire in india Red
(live),Blue(nutal) ,Green(earth),Yello(2nd live)Red and
yello macks 440 v.this is phase voltage

R------connected with--------R
y------connected with--------Y
B------connected with--------B
G------connected with--------G = for 440 v

Lne to line ********

Live------connected with--------Live
Nutal------connected with--------Nutal
