TELEMETRY SYSTEM FOR CENTRIFUGAL PUMPS WITH REDUNDANT IMMERSED PART Russian patent published in 2017 - IPC H02H3/05 

FIELD: electricity.

SUBSTANCE: in a telemetry system for centrifugal pumps with a redundant immersed part comprised of a main unit and a spare unit connected to a switch comprising a ground segment consisting of a constant voltage source of positive-polarity connected to the first electronic key, and a constant voltage source of negative-polarity connected to the second electronic key. The first and the second electronic keys are connected to the control and data processing unit, and a neutral conductor is connected to the switch, the first and second electronic keys, and the control and data processing unit.

EFFECT: increasing the reliability of the telemetry system, as well as reducing the costs of tripping operations, if the immersed part of the telemetry system fails.
