ABSTRACT:
A centrifugal pump is lowered into a well and retrieved from the well by means of its power cable. The power cable has a single conductor. The pump has a downhole electrical motor which is three-phase. Single-phase AC power will be supplied from the surface down the conductor, with the return being the casing. A phase converter converts the single-phase AC power to three-phase AC power downhole for driving the pump motor.
