Tap changers compensate for small voltage variations along the distribution system. Some details on this would be great. The externally operated tap changer is a single phase five position design for de energized operation.

A dual voltage switch permits use of the same transformer on. Provide you with reliable and cost effective transformer products matched to your system requirements. A single phase as is the case in one pole mounted distribution transformer as well uses the neutral from a three phase system.
