FIELD: engines and pumps.
SUBSTANCE: group of inventions relates to a system of an electric submersible pump. System comprises a multiphase electric motor functionally connected with a hydraulic pump, herewith the motor contains a star connection point; a telemetry circuit functionally connected to the star connection point, herewith the telemetry circuit generates AC telemetry signals; a multiphase power cable functionally connected with the motor; and a tuning filter functionally connected with the multiphase power cable, herewith the tuning filter passes and amplifies the alternating current telemetry signals generated by the telemetry circuit. Telemetry signals of alternating current are transmitted to the multiphase power cable through the star connection point.
EFFECT: proposed is a telemetering equipment for systems with a multiphase electric motor.
