The scope of this guide is the definition of load models for various conventional and emerging elements in the generation, transmission, distribution, and customer sectors at all voltage levels. This includes guidance for developing load models, identifying load model parameters, and utilizing measurement data for load model development at various voltage levels. It also includes modeling practices for emerging elements such as power electronic connected elements, electrical vehicles and… read more charging stations, better utilization of information and communication technology (ICT ) infrastructures in load model development, and dynamics associated with customer involvement. read less

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.
