Power transformers - DC magnetic bias suppression devices Ingestion-build-141043 Mechanical properties of fasteners made1 Scope This document specifies requirements for devices for the suppression of DC magnetic bias of power transformers and convertor transformers. It includes requirements for service conditions, structures, testing, packing, transport and storage. The devices are connected to neutral points of power transformers and converter transformers to suppress DC bias current in the case an HVDC system is operated in monopole ground return mode or bipolar
