What will happen if the transformers working in parallel are not connected with regard to polarity ?
A)The power factor of the two trans-formers will be different from the power factor of common load
B)Incorrect polarity will result in dead short circuit
C)The transformers will not share load in proportion to their kVA ratings
D)none of the above

Question

Quizplus · Accepted Answer

Incorrect polarity connection in transformers working in parallel can lead to a phase difference of 180 degrees between their secondary voltages, effectively creating a scenario where the voltages are opposing each other. This can result in a very low impedance path for the current, essentially creating a dead short circuit condition.
