To find the power factor of a transformer, you can use the formula: Power Factor (PF) = Real Power (P) / Apparent Power (S). First, measure the real power in watts (P) consumed by the load connected to the transformer. Then, calculate the apparent power (S) in volt-amperes (VA) by multiplying the voltage (V) and current (I) supplied by the transformer. Finally, divide the real power by the apparent power to obtain the power factor.
