A transformer rated at 10 kW is used to connect a 5 kV transmission line to a 240 V circuit. The ratio of turns in the windings of a transformer
Options
(a) 5
(b) 20.8
(c) 104
(d) 40
Correct Answer:
20.8
Explanation:
A 5 kV has to be connected to a 240 V circuit. This is a step down transformer. The ratio of primary [5000 V / 240 V] = n(ᴘ) / n(ѕ). Primary has 20.8 times the turns in the secondary.
