PHASE
VOLTAGE AND PHASE CURRENT
The
voltage measured between any phase and neutral point is called as phase voltage
The
current passing through any branch of the three phase load is called phase
current.
Three Phase Loads are two types
1.
Star connected load
2.
Delta connected load.
Star Connected Load
From
the Figure 1.7, VRN VYN VBN are phase voltages
and I, Iy and I are phase current.
For
star connected load line = Iphase
Delta Connected Load
