Answer / prasad

Star or Delta are types of winding connections for 3 phase
systems. The line current is the current passing thru
conductor to these windings. The ammeter is generally used
to measure current thru those conductors & not winding.
This current is known as line current. While the current
passing thru each phase of winding is known as phase
current.
In Star winding entire line current passes thru
individual phase i.e. I(ph)=I(L)
In Delta winding however line current gets divided in two
windings. Here I(ph)=I(L)/1.732. Here 1.732 is square root
of 3.

Answer / mani

The phase current is current flow between phase to neutral
is called phase current and the line current is current
flow between two phases is called line current.
In Star winding entire line current passes thru
individual phase i.e. I(ph)=I(L)
In Delta winding however line current gets divided in two
windings. Here I(ph)=I(L)/1.732. Here 1.732 is square root
of 3.

Answer / gagan kumar gupta

in star system line current will equal to phase current and
delta system occured line current will equal 1.732*phase
current

Answer / kupstar tange

Line current is the current that is flowing from an AC supply and Phase current is the current that is flowing through each phase in the system.
In a star system the line current is equal to the phase current (IL = IP)
in a delta system, the line current is divided by 1.732 to get the phase current ( IP = IL/1.732)

Answer / mandeep

In a 3-phase system current accross any one phase and
neutral is called phase current whereas current accross any
two phases is called phase current.In star connection phase
currrent = line current wheras in delta connection line
current = 1.732 phase current.

Answer / rajeev kr. roy

in 3 phase system star and delta connection r used
according 2 requirement.now,phase current is d current
between any phase,line current is d current betwen one
phase and neutral line. in y-y connection line
current=phase current,in delta connections line
current=1.732 times of phase current.

Answer / asjad iqbal

in there phase supply mean star delta .no ny diffrance
between line curent and phase curent.

Answer / deepak ranu sharma

IN STAR CONNECTIONS THERE IS A NEUTRAL POINT SO PHASE
CURRENT IS 1.732 TIMES OF LINE CURRENT AND LINE CURRENT IS
THAT CURRENT WHICH IS PASSING THROUGH A LOAD THROUGH PHASE
AND NEUTRAL.

IN DELTA CONNECTIONS THERE IS NO NEUTRAL SO THE LINE
CURRENT IS SAME AS PHASE CURRENT.

Answer / deepak ranu sharma

IN THE SYSTEM OF 3 PHASE STAR CONNECTIONS THERE IS A
NEUTRAL POINT SO THE PHASE CURRENT IS 1.732 TIMES MORE THAN
LINE CURRENT.AND IN DELTA CONNECTIONS LINE CURRENT IS EQUAL
TO PHASE CURRENT.
