Example:
A measurement of the voltage and current in
one of the lines in a three phase, delta
connected system read 22 volts and 10 amps.
Determine the phase voltages and phase
currents.

In Delta
VL = VP
Therefore the phase voltages are
22 volts

In Delta
IL = √ 3 Ip
IL = √ 3 x 10 = 1.732 x 10 = 17.32
Therefore the phase current is 17.3 A
