Question

Voltage applied to transformer primary is increased keeping v/f fixed

Answer 1

Answer:

Core loss will increase and magnetizing current remain same

Answer 2

Answer:

Explanation:

Transformer Definition:

A transformer is a device that converts electric energy from one alternating-current circuit to one or more other circuits by increasing (stepping up) or decreasing (stepping down) the voltage.

As the voltage rises while the V/f ratio remains constant, the frequency rises as well. As a result, hysteresis and eddy current losses will rise, and core losses will rise as well. The magnetizing current will be constant since the V/f ratio is constant.
