 Part 1:      Transformer Design and Design Parameters

This presentation will be on the Basic of Transformer Design. The presentation will explain how a transformer designer interprets parameters such as MVA, lightning Impulse, Switching impulse, Percentage Impedance supplied by a customer. It will touch on Power rating[MVA], Core, Rated voltages, Insulation Coordination, Short-circuit Impedance, Short-circuit Forces, Loss evaluation, Temperature limits, Cooling, Sound Level .. etc. It will also explain overload and life expectancy of a transformer as well when Delta winding is needed in Wye-Wye connection.  The presentation will answer why in North America we like to regulate from low voltage side whereas in Europe regulates from high voltage side.

 Part 2:     Transformer Manufacturing Processes

This presentation will be on the Industry wide manufacturing process to build a transformer in the shop floor. Processes will cover Core Construction, Insulation, Windings, Core and Coil, Processing, Tanking, Testing and Shipping.  Some of the hold-points during the processes will be explained as well what a customer should look into while doing factory inspection.  The presentation will also cover reconnection both in LV and HV, LTC Tap changer both in tank and separate tank, Lead works.
