What is the difference between phase current & line
current, how both can be measured in star and delta system
Answer Posted / 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.
