Method and apparatus for contactless voltage and current estimation through measurements of electric and magnetic fields with redundant sensor arrays

A detector system for contactless current sensing, the detector system comprising:

• a frame having conductor receiving locations configured to receive a plurality of current carrying conductors and to support the conductors in a fixed arrangement relative to the frame;
• a plurality of magnetic field sensors supported by the frame in a redundant array in a fixed relationship with respect to the conductor receiving locations to sense a magnetic field in a vicinity of the conductors during operation;
• and
• a computing system communicatively coupled to the magnetic field sensors, the computing system configured to receive magnetic field data from the redundant array of magnetic field sensors and to generate an estimated current by utilizing an estimator algorithm that accounts for external magnetic field disturbances on the magnetic field in the vicinity of the conductors to enhance the accuracy of the contactless current sensing of the detector system.
