Abstract
A motor system is disclosed comprising: an electrical conductor in the form of a coil or winding; an electrical insulator insulating the electrical conductor; a discharge sensor arranged and configured to measure a parameter indicative of an electrical current in the insulator; and a voltage controller for controlling a voltage signal applied to the electrical conductor based on a value of the parameter measured by the discharge sensor.
Claims13
A system comprising:
- a discharge sensor configured to measure a parameter indicative of an electrical current in an electrical insulator of an electrical conductor;
- and
- a voltage controller for being connected to the discharge sensor for controlling a voltage signal applied to the electrical conductor based on a value of the parameter measured by the discharge sensor;
- wherein the voltage controller is configured to control the rate of change of amplitude of the voltage signal applied to the electrical conductor with time (dV/dt) based on the value of the parameter measured by the discharge sensor:
- and
- wherein the voltage controller is configured to decrease said rate (dV/dt) if the value of the parameter measured by the discharge sensor is above a first set-point value and/or to increase said rate (dV/dt) if the value of the parameter measured by the discharge sensor is below a second set-point value.
