Abstract: An electric submersible pump system can include a multiphase electric motor operatively coupled to a fluid pump where the multiphase motor includes a wye point; telemetry circuitry operatively coupled to the wye point where the telemetry circuitry generates AC telemetry signals; a multiphase power cable operatively coupled to the multiphase electric motor; and a tune filter operatively coupled to the multiphase power cable where the tune filter passes and amplifies AC telemetry signals generated by the telemetry circuitry, the AC telemetry signals being transmitted to the multiphase power cable via the wye point. Various other apparatuses, systems, methods, etc., are also disclosed.

Abstract: A technique facilitates placement of a pumping system, e.g. an electric submersible pumping system, in a borehole. The pumping system is deployed downhole into the borehole via a conveyance which may be in the form of an electric power cable for providing electric power to the pumping system. A measuring device is disposed between the conveyance and the pumping system and connects the pumping system to the conveyance. The measuring device detects engagement of the pumping system with downhole equipment by monitoring a selected property, e.g. load on the conveyance.
