SYNCHRONOUS MACHINE

摘要

A synchronous machine is intended for direct connection to a distribution or transmission network. At least one stator winding (2) of the machine comprises at least one electric conductor, a first layer with semiconducting properties surrounding the conductor, a solid insulating layer surrounding the first layer, and a second layer with semiconducting properties surrounding the insulating layer. Measuring means (4) are also arranged to sense the voltage in the stator winding. In a method for measuring the voltage in the stator winding of such a machine, the phase of the measured signal is shifted to coincide with the phase position of the total voltage of the stator winding.
