Precautions for inspection of instrument equipment in high temperature weather

Notes on specific inspection items of electrical equipment; 1. Inspection of transformers: 1) Observe the oil level of the transformer: the oil in oil-immersed transformers plays a role in cooling and insulation, and the oil level is determined by the temperature. Changes, so the oil level corresponding to different temperatures is engraved on the transformer. When the oil level is found to be too low, measure and compare the temperature of the transformer, and carefully observe whether there is any oil level on the transformer body.
