An 18-kVA, 7000V / 200V transformer has the following resistors and reactances: RP = 30Ω RS = 0.06Ω XP = 40Ω XS = 0.06Ω RC = 250 KΩ XM = 32 KΩ a.- Find the equivalent circuit referred to the high voltage side. b.- Assuming that the transformer is delivering its nominal load to the charge with a voltage of 200V and a power factor of 0.9 forward. What is the input voltage of the transformer? (note: assumes current through XM and RC is very small, that is negligible)

Single Phase Transformer

A single-phase transformer is a type of power transformer. It is an electrical device that accepts converts the single phase alternating power into single phase alternating power. In this power conversion the voltage is stepped up or down. If the voltage is stepped up, the current will be stepped down and if the voltage is stepped down, the current will be stepped up.
