Transformer oil inevitably absorbs moisture, gas, and particulate impurities during long-term operation. These contaminants severely reduce the oil's insulation performance, thereby weakening the transformer's internal insulation strength. When insulation performance drops to a critical value, it m

When conducting transformer turns ratio and group tests in the field, several common problems repeatedly arise: single-phase phase-by-phase testing requires separate measurements of phases A, B, and C; slight differences in contact resistance during the three wiring operations can reduce the lateral
