BS PD IEC/TS 61463:2016, which is a Technical Specification, is applicable to alternating current and
direct current bushings for highest voltages above 52 kV (or with resonance frequencies
placed inside the seismic response spectrum), mounted on transformers, other apparatus or
buildings. For bushings with highest voltages less than or equal to 52 kV (or with resonance
frequencies placed outside from the seismic response spectrum), due to their characteristics,
seismic qualification is not used as far as construction practice and seismic construction
practice comply with the state of the art.This document presents acceptable seismic qualification methods and requirements to
demonstrate that a bushing can maintain its mechanical properties, insulate and carry current
during 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 60137IEC 61462IEC 62155IEC 62217ISO 2041IEC 60721-2-6IEC 60068-2-6:2007IEC 62271-207:2012IEEE Std 693-2005JEAG 5003-2010IEC 62231All current amendments available at time of purchase are included with the purchase of this document.
