Answer to Question #283254 in Psychology for Shreyash

Question

1.find out the full load primary current and transportation ratio of a single phase 10 KVA, 2200/110V transformer

Answer 1

For the transformer in the question, rated current is 10,000 VA / 110 V = 91 A.

Internal impedance = 110V / 91 A = 1.2 Ohms.

When short circuited, the current will be 110 V / 1.2 Ohms = 92 Amps.
