Abstract
Systems and methods for authentication may include balancing an unbalanced power cable using a transformer that has one or more phases by selecting a voltage on a tap handle; disposing a first bushing on one or more phases at a different voltage than the selected voltage; and balancing the unbalanced power cable based on the disposition of the first bushing on the one or more phases at the different voltage.
Claims21
A power cable, comprising:
- three or more conductors, wherein at least one of the three or more conductors comprises an impedance value differing from impedance values of each of the remaining three or more conductors, wherein the cable is converted from an unbalanced mode to a balanced mode by disposing a bushing on one or more of three phases at a voltage for an electrical application.
A system comprising:
- an electrical submersible pump operably connected to a power supply by a power cable, wherein at least a portion of said power cable comprises:
- three or more conductors, wherein at least one of the three or more conductors comprises an impedance value differing from impedance values of each of the remaining three or more conductors, wherein the cable is converted from an unbalanced mode to a balanced mode by disposing a bushing on one or more of three phases at a voltage for the electrical submersible pump.
