1. Causes of Failure in Agricultural Distribution Transformers(1) Insulation DamageRural power supply typically utilizes 380/220V mixed supply systems. Due to the high proportion of single-phase loads, distribution transformers often operate under significant three-phase load imbalance. In many cases, the imbalance exceeds the permissible range specified in standards, causing premature aging, deterioration, and failure of transformer winding insulation, ultimately leading to burnout.When distrib

Transformers play an indispensable role in power systems, and almost every electrical device relies on their stable power supply. Sometimes you may find that the transformer's voltage is unstable, or even unbalanced. This phenomenon not only affects the operating efficiency of equipment but also may bring a series of serious safety hazards. What exactly causes transformer voltage imbalance? And how to effectively solve this problem?1.Three-Phase Load ImbalanceThe voltage balance of a transformer
