About this document
Insulation Temperature Limits in Transformers by Sri Yadav is a document available to read on EtoBox.
Low density pressboard insulation between transformer core packets and tie plates can deteriorate if heated over 100–110°C for long periods. Standards provide temperature limits for metallic parts in contact with insulation, but are vague on limits for pressboard in this specific location. Clarifying safe temperature limits based on the type of insulation material could help prevent failures requiring repairs.
