RIF® bushings: The paperless, dry-type bushing technology

Abstract

Paper-insulated bushings (OIP and RIP) have been the dominant bushing type for the power transformer industry for many years. However, as our transformer assets age, bushing failures can become more frequent. Resin-impregnated fibre bushings offer the user a paperless and dry-type alternative for MV, HV and EHV condenser transformer bushings. Two technologies are currently offered: resin-impregnated fiberglass (a proprietary technology trademarked RIF®) and resin-impregnated synthetic (RIS). This article will discuss the RIF® bushing technology, which offers an extended range of capabilities including an optional line of smart bushings that use integrated monitoring components.
