Comparison of Loading Guide Standards ieee and IEC ieee IEC ieee Std IEC 60076-7-2018 ieee Clause Title Clause ieee Guide for Loading Mineral-Oil-Immersed Transformers and Step-Voltage Regulators Matching Clause POWER TRANSFORMERS Part 7: Loading guide1 for mineral-oil-immersed power transformers Scope This Guide provides recommendations for Loading mineral-oil-immersed transformers and step-voltage regulators with insulation systems rated for a 65 C average winding temperature rise at rated load. Because a substantial population of transformers and step-voltage regulators with insulation systems rated for 55 C average winding temperature rise at rated load are still in service, recommendations that are specific to this equipment are also included.
insulation is considered new and the final state for which dielectric stress, short circuit stress, or mechanical movement, which could occur in normal service, and could cause an electrical failure. 3.10 transformer insulation life total time between the initial state for which the insulation is considered new and the final state…
