[0002] Small transformers mainly refer to transformers with a single-phase capacity below 20 kV·A and a three-phase capacity below 50 kV·A. They are characterized by small volume, low cost, and less wire usage. The load rate and utilization rate of small transformers are generally low. The inductive loads they carry are generally not compensated capacitively. Small transformers are a commonly used device in factory electrical control systems.
