This 3 part series covers the refurbishment of an old 2kVA autotransformer.
This is in the 'projects' section rather than the repairs one, as the transformer itself was fully working, and just needed a new case and control panel.
Overview Part 1
Initial examination and basic testing of an old steel cased autotransformer.
Theory and Demonstration Part 2
Basic theory of operation for transformers, autotransformers and variacs with a practical demonstration of measuring voltages.
Rewiring and reassembly Part 3
Rewiring and reassembly of the steel cased 2kVA autotransformer, including voltage meters,m current meters and new control switches.
