shorting out sliprings
(OP)
I have a 3.3kV 400kW slip ring motor. Does any know of a system where the slip rings can be shorted at the motor once it has started and possibly the brushes lifted off the slip rings

RE: shorting out sliprings
I have seen motors used with the rings permanently shorted and the brush gear removed, but these are driven by a VSD. If you use any form of primary starter, you must have resisance in the rotor circuit during start or no torque will be developed.

Agreed, but if you are trying to mod an existing machine, then it gets difficult due to the confined space.
