Question

what is called regulation transformer​

Answer 1

Answer:

regulation. Voltage regulation is the difference between the transformersecondary No-Load and Full-Load voltage with respect to its Full-Load voltage. Essentially, every transformer has a voltage drop caused by its own impedance (which is composed of its winding resistive and inductive properties).

hope this makes sense

Answer 2

Answer: The transformer which changes the magnitude and phase angle at the certain point in the power system is known as the regulating transformer. It is mainly used for controlling the magnitude of bus voltage and for controlling the power flow, which is controlled by the phase angle of the transformer
