Common guidelines for reliability data collection in Scandinavia

The paper presents a work that has been carried out in a common Scandinavian research project. The aim of the work was to establish common guidelines in Scandinavia for fault reporting, and to prepare the foundation for a Scandinavian fault database for voltage levels above 1 kV. The Nordel guidelines for reporting of disturbances above 100 kV are the most important basis for this work. The paper also discusses how users of a future database can be given access to the fault reports through the internet. The long-term goal of utilising component information in addition to the corresponding fault data through an internet database is also pointed out.
