what is the power factor of a transformer bushing?

The power factor of a transformer bushing refers to the ratio of the real power flowing through the bushing to the apparent power. It indicates the efficiency of the bushing in transferring electrical energy. A power factor close to 1 signifies efficient energy transfer, while a lower power factor indicates reactive power losses. Typically, transformer bushings are designed to have a high power factor to minimize losses and improve overall transformer performance.
