A Scott-Tee Transformer (also called a Scott connection) is a type of circuit used to derive two – phase electric power (2-φ, 90 degree phase rotation) from a three phase (3-φ, 120 degree phase rotation) source, or vice-versa.
The Scott connection evenly distributes a balanced load between the phases of the source. These are widely used for heating of Oil/ Petroleum pipe lines

In Hermetically Sealed Transformers, the dielectric insulating fluid in the transformer tank is completely sealed and not connected to atmospheric air. This type of transformer is used in applications where the transformer is to be installed in harsh climatic conditions (moist, smoke, polluted, dusty environment, etc.) or where the user prefers a low maintenance transformer. The design avoids air in the transformer tank, thereby avoiding sludge formation and oxidation of the dielectric fluid.
