  • Inductively coupled sensor and system for use thereof
    Patent number: 11328584
    Abstract: Included are inductively coupled sensors for downhole electric submersible pumps and methods of use. An example inductively coupled sensor comprises an electric submersible pump sensor, at least one receiving coil coupled to the electric submersible pump sensor; wherein the receiving coil is inductively coupled to a three-phase power cable of an electric submersible pump. An example method comprises placing an inductively coupled sensor in a wellbore, conducting current in the three-phase power cable; wherein current in the three-phase power cable induces a voltage in the receiving coil sufficient to power the electric submersible pump sensor, and sensing the operating parameter of the electric submersible pump with the electric submersible pump sensor.
