HOW TO FIND OUT 1. LINE CURRENT, 2. PHASE CURRENT IN AN
ALTERNATOR / TRANSFORMER WHICH IS FEEDING A I)STAR LOAD ii)
DELTA LOAD, USING A CLAMP METER.
NORMALLY WHEN WE USE CLAMP METER IN A DG SET THEN WHAT DO
WE GET?? PHASE CURRENT OR LINE CURRENT.

Lets say we are using transformer,
A delta star transformer, the 3 phases coming out of the
star side of the transformer are the red, yellow and blue
wires abbreviated as R Y and B. The Current flowing through
these wires is the Line current. Using a Clamp meter, we
should clamp the meter to one of the wires say R phase. The
measured value will b Line current passing through R phase.
If the load is Balanced load, then equal amount of current
will flow through the Phases R Y and B respectively. After
that we can measure the Phase current using the formula
given above.

At the starting of dc motor and syn.motor and induction motor high current flowing through the winding. Due to this the windings burnt out. To avoid this different types of starters are used. But incase of transformer what Will be used (At starting no emf is induced in the primary winding)?
