GB/T 45942-2025 Mineral oil-filled electrical equipment—Application of dissolved gas analysis(DGA) to factory tests on electrical equipment
Abstract
This document specifies the sampling procedures, analysis requirements, and steps for conducting dissolved gas analysis in transformer oil during factory testing of electrical equipment (such as power transformers, reactors, and transformers) filled with mineral insulating oil. It also stipulates the requirements for sensitivity, repeatability, and accuracy.
This document applies to the temperature rise test, overcurrent test, long-term no-load test, and insulation test of power transformers and reactors, as well as the impulse test of transformers.
