Abstract: A system for applying power into a wellbore. The system can include a casing, a tubing string, a first and second isolator sub, a power source, and an electrical device. The casing has a first cavity running therethrough. The tubing string is disposed within the first cavity without contacting the casing, where the tubing string has a second cavity running therethrough. The first isolator sub is mechanically coupled to the tubing string and positioned between the neutral section and the power-transmitting section of the tubing string. The power source is electrically coupled to the power-transmitting section of the tubing string below the first isolator sub. The second isolator sub is mechanically coupled to the tubing string and positioned between the bottom neutral section and the power-transmitting section of the tubing string. The electrical device is electrically coupled to a bottom end of the power-transmitting section of the tubing string.
