BS PD IEC/TS 61463:2016

BS PD IEC/TS 61463:2016, which is a Technical Specification, is applicable to alternating current anddirect current bushings for highest voltages above 52 kV (or with resonance frequenciesplaced inside the seismic response spectrum), mounted on transformers, other apparatus orbuildings. For bushings with highest voltages less than or equal to 52 kV (or with resonancefrequencies placed outside from the seismic response spectrum), due to their characteristics,seismic qualification is not used as far as construction practice and seismic constructionpractice comply with the state of the art.This document presents acceptable seismic qualification methods and requirements todemonstrate that a bushing can maintain its mechanical properties, insulate and carry currentduring and after an earthquake.The seismic qualification of a bushing is only performed upon request.Cross References:IEC 60068-2-47IEC 60068-2-57IEC 60068-3-3:1991IEC 60137 IEC 61462IEC 62155IEC 62217ISO 2041IEC 60721-2-6 IEC 60068-2-6:2007IEC 62271-207:2012IEEE Std 693-2005JEAG 5003-2010IEC 62231
