Shunt reactor with auxiliary power

An electric power system comprising:

• a tank;
• a steel core disposed in the tank, the steel core comprising a bottom yoke, a top yoke, a first core limb, a second core limb, and a main limb, the first core limb, the second core limb and the main limb arranged in parallel and in between the top yoke and the bottom yoke to form a support for a magnetic flux through the steel core;
• a primary winding wound around the main limb to generate the magnetic flux through the steel core;
• an auxiliary winding wound around at least one of the bottom yoke, top yoke, first core limb, and second core limb, the auxiliary winding configured to generate auxiliary power from the magnetic flux generated by the primary winding, the primary and the auxiliary windings electrically insulated from the steel core and from each other;
• and
• a cooling fan configured to be driven by the auxiliary power generated by the auxiliary winding.

A method comprising:

• winding a primary winding around a main limb of a steel core comprising a bottom yoke, a top yoke, a first core limb, a second core limb, and the main limb, the first core limb, the second core limb and the main limb arranged in parallel and in between the top yoke and the bottom yoke to form a support for a magnetic flux through the steel core;
• winding an auxiliary winding around at least one of the bottom yoke, top yoke, first core limb, and second core limb, the auxiliary winding configured to generate auxiliary power from the magnetic flux generated by the primary winding, the primary and the auxiliary windings electrically insulated from the steel core and from each other;
• disposing the steel core in a tank;
• and
• connecting the auxiliary winding to a cooling fan configured to be driven by the auxiliary power generated by the auxiliary winding.
