Protective capacitors offer surge protection for AC generators, synchronous condensers and large motors. Dielektrol® is the GE non-PCB power capacitor dielectric system, developed to provide an environmentally acceptable product with superior performance and reliability. Protective capacitors contain a film dielectric and hermetically sealed bushings, which permit mounting of capacitors in an upright position or on the side. GE surge capacitors protect the winding insulation by reducing the steepness of wave fronts applied to or reflected within the machine windings.
