The tests also included a runawayspeed test for 15 minutes at 70 per cent,over-speed, the field being fully these conditions the machine was stators. Figs. 2J and 23 are views takenafter the erection of the machines in thepower-station. It will be noted fromthe engravings that the stator frameshave been made each in quarters forease in transport. The figures also showthe arrangements which have been madeto allow the stator to be racked over forthe inspection of the windings or for re-pair. The stator windings consist offormer-wound coils insulated with
