Transformer theory, power and distribution transformers, instrument transformers, cooling, tap changers, impedance, testing, and oil systems — worked from the EMF equation through condition monitoring.
This module builds from Faraday's law and the EMF equation up through the full set of decisions a utility-scale transformer specification actually requires: cooling-class nameplates and why each fan stage buys diminishing returns, CT and VT burden budgeting, on-load tap changer sizing, and what happens when two paralleled transformers don't share load the way their nameplate MVA ratings suggest.
By the end of this module you should be able to read a DGA report, a TTR/insulation-resistance test set, and a Buchholz relay's two-stage protection scheme as one connected picture of a transformer's actual condition — not three unrelated checklists — and explain why a transformer that passes every individual test can still be quietly losing insulation life faster than its loading history alone would suggest.
