Abstract:
An inductor system for an equipment string configured to be deployed in a well, the equipment string including at least one powered component coupled to a power cable extending between the earth's surface and the equipment string when deployed, and a direct current circuit receiving power via the power cable, the inductor system being configured to be coupled between the powered component and the direct current circuit, the inductor system comprising:an inductor including a conductive coil and a ferromagnetic core;an electrically insulative support structure including an support portion configured to contact and retain the inductor, and an interface portion coupled to the support portion for supporting the inductor in a conductive housing, the support structure electrically isolating the inductor from the conductive housing; andan insulative covering extending over the inductor to isolate the inductor and the support portion from surrounding conductive surfaces within the housing, the support portion including a plurality of support rails secured to the inductor and the insulative covering including at least one insulative jacket disposed around the support rails and the inductor.
