Patent number: 8117739Abstract: An electrical module assembly used in a surge arrester is manufactured by wrapping an electrical module assembly including at least one metal oxide varistor (MOV) disk to which a reinforcing structure including a pre-impregnated epoxy/glass-fiber composite has been applied with shrink film and compacting the wrapped electrical module assembly by heating the shrink film such that the shrink film shrinks and applies a radially compressive force to the electrical module assembly. The wrapped electrical module assembly then is cured at a temperature at which the shrink film no longer applies a compressive force.Type: GrantFiled: January 23, 2004Date of Patent: February 21, 2012Assignee: Cooper Technologies CompanyInventors: Michael M. Ramarge, Alan P. Yerges, David P. Bailey, Roger S. Perkins

Patent number: 7633737Abstract: A liquid immersed surge arrester that protects electrical equipment includes a module assembly. The module assembly includes at least one varistor and a pre-impregnated composite around the at least one varistor. The liquid immersed surge arrester also includes contacts on opposite ends of the module assembly with which the module assembly is connected to electrical equipment to be protected and to electrical ground. The liquid immersed surge arrester also includes a tank that houses the module assembly and the contacts. A fault-tolerant protection device for protecting electrical equipment includes a surge arrester to protect electrical equipment from damage during periods of voltage above a normal operating range. The fault-tolerant protection device also includes a surge durable fuse element to disconnect the surge arrester after failure of the surge arrester to allow unprotected operation of the electrical system.Type: GrantFiled: April 29, 2004Date of Patent: December 15, 2009Assignee: Cooper Technologies CompanyInventors: Michael M. Ramarge, Alan P. Yerges

Patent number: 6847514Abstract: A surge arrester includes a stack of components having at least one varistor. Each component has end faces, at least one of which is mechanically bonded to an end face of another component such that the combined components of the stack define a single, monolithic structure that serves as both an electrically-active element and a mechanical support element of the surge arrester. The surge arrester also includes an insulative housing surrounding the stack of components. The stack of components is capable of withstanding current pulses having magnitudes of 65 kA and durations of {fraction (4/10)} microseconds without significant degradation in operating performance of the stack of components.Type: GrantFiled: December 20, 2002Date of Patent: January 25, 2005Assignee: Cooper Industries, Inc.Inventors: Michael M. Ramarge, David P. Bailey, Roger S. Perkins, Thomas C. Hartman, Alan P. Yerges, Ramon Puyane, David R. Miller

Patent number: 6726857Abstract: The present invention comprises a mixture of hydrocarbons having a well-defined chemical composition that is suitable for use as a dielectric coolant in electrical equipment in general, and specifically in transformers. The dielectric coolants of the present invention are particularly suited for use in sealed, non-vented transformers, and have improved performance characteristics, including decreased degradation of the paper insulating layers, as well as a greater degree of safety and environmental acceptability. The present dielectric coolants comprise relatively pure blends of compounds selected from the group consisting of aromatic hydrocarbons, polyalphaolefins, polyol esters, and natural vegetable oils, along with additives to improve pour point, increase stability and reduce oxidation rate.Type: GrantFiled: November 25, 2002Date of Patent: April 27, 2004Assignee: Cooper Industries, Inc.Inventors: Gary L. Goedde, Gary A. Gauger, John Lapp, Alan P. Yerges
