A single-phase transformer is rated at $2.2\mathrm{kVA},440/220\mathrm{V},50\mathrm{Hz}$. a) What is the secondary current of this transformer, when its secondary is at rated voltage and output kVA is at rated value. b) What is the primary current of this transformer when it is operating in the condition described in (a) c) Primary referred approximate equivalent circuit of a transformer is given in Fig. 3. The transformer in this problem is operating at no-load, at rated primary voltage. What is its core loss? d) What is the current drawn from the voltage source in the condition described in (c).
