    Do Dry‑Type Transformers Need to Be De‑energized?

    Dry‑type transformers are widely applied for local lighting, high‑rise buildings, airports, wharves, CNC machinery and other facilities. Simply put, a dry‑type transformer is a transformer whose core and windings are not immersed in insulating oil. Under what conditions shall a dry‑type transformer be immediately de‑energized? Fire occurs on the dry‑type transformer; the unit must be shut down immediately. Severe damage or discharge phenomena are observed on the transformer bushing. Stop operation immediately and arrange inspection by qualified professionals. Heavy smoke is emitted from the transformer. Abnormal, loud internal noise accompanied by explosion‑like sounds inside the transformer. Immediate shutdown is mandatory to prevent hazardous accidents. Abnormally high and continuously rising temperature under normal load and cooling conditions. When any of the above‑mentioned symptoms appear, the dry‑type transformer must be de‑energized right away. Continuing operation under such faults may cause personal injury as well as permanent damage to the transformer. These issues shall be addressed promptly. Exercise great caution when encountering any of the above‑mentioned conditions to avoid hazards. Yizheng Hongxin Transformer Co., Ltd. specializes in transformers, including dry‑type transformers, power transformers and oil‑immersed transformers. As a transformer manufacturer based in Jiangsu Province, our plant produces dry‑type transformers, power transformers and oil‑immersed transformers.
