Abstract:
1. A system for controlled accelerated thermal aging of electrical windings, wherein the system comprises: A. An electrical winding element and a short circuit conductive element, wherein the electrical winding element has an inner conductive component and an insulation component; wherein each one of the two elements, the electrical winding element and the short circuit conductive element, have two ends, where the two ends of the electrical winding element are attached to the two ends of the short circuit conductive element by means of two connections, wherein the two attached elements, the electrical winding element and the short circuit conductive element, form a closed short circuit; B. A step-up transformer, wherein the step-up transformer uses a controlled variable voltage source, wherein the step-up transformer is connected to the closed short circuit, wherein the step-up transformer using a controlled variable voltage source can provide controlled variable charges to the closed short circuit; C. A reactive power compensation part wrapped around a section of the electrical winding element, wherein the reactive power compensation part has a shielding component and a wrapping component, wherein the shielding component is grounded, wherein the wrapping component is a non-magnetic, non-sparking component; D. A capacitor device, wherein the capacitor device is connected to the reactive power compensation part; wherein charging of the closed short circuit with a controlled charge by the step-up transformer using a controlled variable voltage source, induces heat in the inner conductive component of the electrical winding element, wherein cycles of controlled charges by the step-up transformer using a controlled variable voltage source, generate cycles of flowing current through the closed short circuit, wherein the cycles of flowing current through the closed short circuit produce cycles of heat by induction in the electrical winding element, wherein said cycles of heat produce thermal aging in the insulating component.
