Abstract
Safety control apparatus for limiting voltages on electrical conductors included in a motor power cable that are connected to a motor of an electrical submersible pump assembly are described. The safety control apparatus include circuitry, which when electrically coupled to the electrical conductors of the motor power cable, is configured to controllably connect and disconnect the electrical conductors to and from, respectively, a motor load element, to provide a braking function limiting the motor rotational speed, and thereby limit the voltage level that the rotation of the motor may induce onto the electrical conductors.
