Question
A transformer with a 10 : 1 ratio and rated at 50-kVA, 2400/240-V, 50-Hz is used to step down the voltage of a distribution system.
A transformer with a 10 : 1 ratio and rated at 50-kVA, 2400/240-V, 50-Hz is used to step down the voltage of a distribution system. The low tension voltage is to be kept constant at 240 V.
(a) What load impedance connected to low-tension size will be loading the transformer fully at
power factor (lag) ?
What is the value of this impedance referred to high tension side ?
What is the value of the current referred to the high tension side ?
