          A single phase (1530)-VA, (430)/(150)V transformer is tested.
a) Find per unit equivalent circuit of this transformer
b) At rated condition with .8 pf power factor lagging find voltage regulation
Open circuit test (Low
voltage side)
Short Circuir test
V = rated voltage
I = 1.6 A
P= 45 W
High Voltage side
V=12V
I=rated current
P=30W

Step 1

Given: Rated power (VA) = 1530 VA Rated voltage (V) = 150 V We can use the formula: Rated power (VA) = Rated voltage (V) * Rated current (A) 1530 VA = 150 V * Rated current (A) Solving for Rated current (A): Rated current (A) = 1530 VA / 150 V Rated current (A) = Show more…

A single phase 1530 VA 430/150 V transformer is tested. Find the per unit equivalent circuit of this transformer. At rated condition with 8 pf power factor lagging, find the voltage regulation. Open circuit test (Low voltage side): Short circuit test (High voltage side): V = rated voltage V = 120 V I = 1.6 A P = 45 W I = rated current P = 30 W
