Recommended Practice for On-load Capacity Switching Distribution Transformers | August 25
This recommended practice provides guidance and references for the design, manufacture, testing and selection of oil-immersed on-load capacity switching distribution transformers with rated frequency of 50 Hz/60 Hz, voltages of 10 kV or below, and rated capacity of 750 kVA and below. On-load capacity switching distribution transformers are transformers with two rated capacities and equipped with additional components to control the operating capacity for energy saving purposes.
