1200 120 v. 60 Hz., real step-down transformer has the following parameters: R= 20 KNX = 10 K. and all the leakages and copper losses of both the primary and secondary windings are negligible. Suppose that a load is connected to the secondary side and consists of a resistor R = 10 2 and a capacitor Co both of which are connected in parallel (a) Draw an equivalent circuit that is referred to the primary-side: (5) Determine C such that the primary-side can have a unity power factor: (C) Find the primary-side current phasor if the input is the rated voltage in (b) (d) Find the transformer eficiency y under the condition in (b)
