nieuwe onderwerpen Cigré int. actie

A2-NL Planning 2014

• 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 ▫ · Experience with new insulating liquids, gas and solids (maintenance, performance, diagnostics, life cycle costs), improved winding and

core material and technologies ▫ · Experience with new technologies for components: bushings, tap changer and other transformer accessories ▫ · High-Temperature Supraconductor (HTS) transformer experience and applications
