1. An electrical submersible pumping (“ESP”) system comprising:
a driveshaft assembly that comprises elongated segments that include a pump shaft;
an electrical motor coupled with an end of the driveshaft assembly, and that when energized rotates the driveshaft assembly in a first direction;
a pump coupled with an end of the driveshaft assembly distal from the motor; and
a one-way clutch train in the driveshaft assembly that is rotationally disengaged with the driveshaft assembly when the driveshaft assembly rotates in the first direction, and that is rotationally engaged with the driveshaft assembly when the driveshaft assembly rotates in a second direction that is opposite to the first direction, and that comprises,
a shaft-to-shaft clutch comprising,
an outer race on an outer surface of one of the segments,
an inner race on an inner surface of an adjacent segment, and
sprag type elements between the inner and outer races, and
a shaft to housing clutch coupled between the one of the segments and an outer housing, the shaft to housing clutch being selectively changeable between an engaged configuration and a disengaged configuration, and when the shaft to housing clutch is in the engaged configuration, the housing is rotationally coupled to the one of the segments by the shaft to housing clutch, and when the shaft to housing clutch is in disengaged configuration the one of the segments is rotatable with respect to the housing.
