HOW TO FIND OUT 1. LINE CURRENT, 2. PHASE CURRENT IN AN ALTERNATOR / TRANSFORMER WHICH IS FEEDING ..

Answer / debasish das

we can not measure phase current in three phase suply. if
we measure the current that will be the line current .and
if we devide this current by .732 then we will get phase
current

HOW TO FIND OUT 1. LINE CURRENT, 2. PHASE CURRENT IN AN ALTERNATOR / TRANSFORMER WHICH IS FEEDING ..

Answer / vivek

dear sudheer, the question was to find it out practically,
as i wrote, using the clamp meter ..... theory we all know
but thequestion is how to apply the knowledge .... let me
ask the question in a different way..... where exactly
would u put the clamp meter in order to measure the line
curren and phase current?? because phase current passes
through the neutral and the line current through two
phases. .... so i guess one might need to open theload or
the source especially in order to measure the phase
current ....if anybody knows a link from where i can get
practical knowledge like this then pl let me know....
thanks.
