Abstract of the Disclosure An air core reactor of the type having a plurality of coaxial coil windings connected electrically in parallel by structurally rigid spiders at opposite ends of the reactor. There are two electrically conductive spiders at at least one end of the reactor. Selected ones of the coil windings are connected to one of the two spiders and further selected ones of the coil windings are connected to the other of the spiders at the one end. In the preferred form the windings connected to the respective spiders are circumferentially offset from one another around the coaxially disposed coils. In a further preferred embodiment, there are two electrically conductive spiders at each of opposite ends of the coaxial coils. In a still further preferred form, at least some of the coil windings are wound at least two conductors high with the same number of turns and wherein the ends of said two conductors are circumferentially offset from one another by preferably 180°. In the most preferred form all coil windings are wound at least two conductors high ("n" high where "n" is an even number). The two spiders at one end may be a single structural unit with two separate electrically conductive spiders mounted thereon and carried thereby, or they may be two separate rigid electrically conductive structures that are internested or stacked one on top of the other. The two spiders at each of the opposite ends and the coil windings connected in parallel with the connections offset circumferentially provides a coil arrangement which can be checked readily for faults which are even relatively minor in nature or the detection of such faults in an operating system can be used to initiate a shut down of the system or parts thereof before substantial damage takes place.
