Abstract: The present disclosure relates to a stripping tool, and an arrangement for stripping a conductor bar from a slot of a core of an electric machine. The disclosure provides a device to facilitate the removal of a conductor bar out of a slot of an electric machine. A stripping tool is described with a piston and a support to apply the piston to the core, a rope to be wound around the conductor bar, and a puller suitable to move the rope vertically to the core to pull the conductor bar out of the slot by means of the rope.

Abstract: The present disclosure relates to a chamber for housing strands of a stator bar for electric machines. The problem to provide a reliable chamber for a stator bar of an electric machine is solved with a stator bar chamber engaging a stator bar in an electric machine. The chamber includes a number of hollow conductors in a first straight part of the chamber, a number of hollow conductors in a second tapered part, and a number of hollow conductors and adjacent solid conductors in a third straight part. The first part of the chamber is closed with a ring mounted at the edge of the first part and a nipple adapted to the ring.

Abstract: This invention relates to determining the functional capability of an electric machine by checking the degree of contamination in a slot for housing a conductor bar. It is an object of the invention to appropriately determine the pollution of a slot of an electric machine. Disclosed is a tool to measure a contamination in a slot for a conductor bar of an electric machine, with a voltage generator to apply a voltage at the slot and a voltmeter to measure a voltage drop along the slot, and a processor to calculate the contamination from the voltage drop. Further disclosed is a method to measure a contamination in a slot for a conductor bar of an electric machine with the steps of applying a voltage at the slot, measuring a voltage drop along the slot, and calculating the contamination in the slot on basis of the measured voltage drop.
