The disclosed embodiments include a power and data delivery system for downhole gauges of a well. The power and data delivery system includes a three-phase power supply coupled to a power cable to supply power to a downhole motor positioned along a wellbore. Additionally, the power cable transmits power and data signals. The power and data delivery system also includes a downhole gauge coupled to the downhole motor, and the downhole gauge transmits downhole data signals along the power cable to a gauge surface panel. Further, the power and data delivery system includes at least one gauge positioned remotely from the downhole gauge and coupled to the power cable. The at least one gauge also transmits gauge data signals along the power cable to the gauge surface panel.

An electrically powered artificial lift system includes a tubular for conveying a wellbore fluid upward and a downhole pump that urges the wellbore fluid into the tubular. A power cable conveys a three-phase power signal to the pump motor on three conductors. One of the three conductors is coupled to an internal node of a high-to-low voltage (HLV) source coupler via a low frequency blocking filter that shields the internal node from the motor power signal while conveying a sensor power signal from the internal node to the selected conductor and conveying a telemetry signal from the selected conductor and to the internal node. A similar downhole coupler couples a wye point of the motor to a downhole sensor assembly to supply the sensor power signal and to receive the telemetry signal.
