BS PD IEC/TR 62757:2015, which is a technical report, deals with fire prevention measures on convertersand their valve halls for high voltage direct current (HVDC) systems, static VAR compensators(SVC) and flexible AC transmission systems (FACTS). It is intended to be primarily for the useof the utilities and consultants who are responsible for issuing technical specifications for newconverter valves and valve halls. It concerns fire incidents in HVDC projects using linecommutated converters (LCC) or voltage sourced converter (VSC) technology and it is fromthese projects that most examples of fires and fire incidents are taken. This technical reportalso addresses converter valves and valve halls for SVC and FACTS.This technical report provides general recommendations to be considered while preparingspecifications for these systems. Specific requirements for a particular project need to beclearly specified and mutually agreed upon between the supplier and the purchaser.Cross References:IEC 60331IEC 60332IEC 60695-1-10IEC 60695-1-11IEC/TS 60695-1-20IEC/TR 60695-1-21IEC 60695-1-30IEC 60695-11-10 IEC 60707:1999IEC 61034-1ISO 181:1981ISO 4589-1:1996ISO 4589-2:1996ISO 4589-3:1996ISO 13943IEEE 979-1994IEEE P979/D7IEEE SA 1202-2006IEEE SM 369-9 PWRDCIGRE Technical Brochure 136NFPA 850
