Short note on auto transformer
SpletAn auto transformer consists of a single copper wire, which is common in both primary as well as secondary circuit. The copper wire is wound a laminated silicon steel core, with at least three tappings taken out. Secondary and primary circuit share the same neutral point of the winding. The construction is well explained in the diagram. SpletThe power transformer is costly equipment in the substation and this requires approximately 50% of the capital outlay on the erection of substation. Due to its vital role, …
