An autotransformer is a transformer which has part of its winding common to the primary and secondary circuits. Fig. 1(a)…
Figure shows diagrammatically auto-transformer tap changing. Here, a mid-tapped auto-transformer or reactor is used. One of the lines is connected…
The excitation control method is satisfactory only for relatively short lines. However, it is not suitable for long lines as…
Transformers are susceptible to damage by secondary short-circuit currents having magnitudes that can be many times rated load current. The…
