- Homework Statement
- A three phase delta connected load, each phase of which has an inductive reactance of 40Ω and
a resistance of 25Ω (connected in series), is supplied from the secondary of a three phase star
connected transformer which has a phase voltage of 240V. With the aid of a circuit diagram
calculate
(a) voltage magnitude across each phase of the load
(b) the current magnitude in each phase of the load
(c) the magnitude of the transformer winding currents
(d) the total real power and power factor
- Relevant Equations
- Vph=root3.Vl
total real power = VIcos angle
pf = P/S
so far on this question i have calculated the phase voltage as 415 Volts using by multiplying the line voltage by root 3. i know how to calculate (d) but am struggling with finding the equations to satisfy
