Air-core reactors for use with power transmission systems

A system comprising:

• a power transmission system, the power transmission system comprising an air-core reactor comprising:
• a main coil electrically connected to a main circuit of a power transmission system, the main coil comprising:
• a first solenoid having a first diameter;
• and
• a second solenoid having a second diameter, wherein the first diameter and the second diameter are different;
• and
• an auxiliary coil comprising a third solenoid,
• wherein the auxiliary coil is electrically connected to an auxiliary circuit of the power transmission system,
• wherein the main circuit is connected to first devices,
• wherein the auxiliary circuit is connected to lower power devices than the first devices,
• wherein the first solenoid and the second solenoid are arranged concentrically,
• wherein the auxiliary coil is magnetically coupled to the main coil, and
• wherein the auxiliary coil is arranged concentric to the main coil.

A method of implementing an air-core reactor in a power transmission system, comprising:

• arranging a first solenoid having a first diameter concentric to a second solenoid having a second diameter;
• disposing an auxiliary coil comprising a third solenoid within a main coil,
• wherein the main coil comprises the first solenoid and the second solenoid, and
• wherein the auxiliary coil is magnetically coupled to the main coil;
• electrically connecting the main coil to a main circuit of the power transmission system;
• and
• electrically connecting the auxiliary coil to an auxiliary circuit of the power transmission system,
• wherein the auxiliary coil is electrically connected to an auxiliary circuit of the power transmission system,
• wherein the main circuit is connected to first devices, and
• wherein the auxiliary circuit is connected to lower power devices than the first devices.
