On-load tap changers (or circuit tap changers), permit tap changing and hence voltage regulation with the transformer on-load. Tap changing is usually done on the HV(High voltage) winding for two reasons:

  1. Because the currents are lower, the tap changer contacts, leads, etc., can be smaller.
  2. As the HV winding is …
