21225373.52 Radial and Ring Main Distribution System is specially designed to illustrate the working phenomenon of Distribution System configured as Radial and Ring Main Distribution System. Distribution System is the part of electric power system which connects the high voltage transmission networks to the low voltage consumer service points.
Distribution Systems should be designed in a way that Voltage variation at consumer terminals must be maintained with in ±5%. 21225373.52 provides complete learning content to develop Ring and Radial Distribution System manually. The Voltage regulation is studied by performing experiments & comparison. It includes inbuilt DC Variable Supply with adequate protections, precise digital meters are used along with separate sections for Radial and Ring Main Distribution System so that students can understand the significance of these systems in a proper sequence.
