A power distribution transformer is used to step down medium voltage (for example, 11-33 kV) to low voltage levels suitable for end users, such as 400/230 V in many systems. It is installed on poles, pads or inside kiosks near load centers. Distribution transformers are designed for high efficiency at light to medium loads since they are energized continuously and often lightly loaded. They typically have fixed or limited tap ranges, simple protection and focus on robustness, low no load losses and minimal maintenance in everyday service.
