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.

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
