• Preferential Subjects for Paris • PS1: Best practices for transformer asset management ▫
· Health index as a tool for condition assessment, applications of a transformer fleet ranking by condition and criticality (…….paper NL: DNV-KEMA, Mischa de Vreede /Jos Wetzer)
▫
· Best practices for maintenance and reinvestment strategies, solid insulation ageing markers, on-line monitoring and diagnostics, role of post-mortem investigations
▫
· Mitigation techniques against major events, spare transformer requirements and practices
• PS2: Transformers for specialized applications ▫ ▫ ▫ ▫
· Application of phase-shifting, converter, industrial, offshore/sub sea, variable shunt reactors, etc. · Specification, design, manufacturing and testing · Performance, reliability, operation & maintenance
• PS3: Field experience with the use of non-conventional materials and technologies ▫
