1750 awesome technical articles
Hi, I'm an electrical engineer, programmer and founder of EEP - Electrical Engineering Portal. I worked twelve years at Schneider Electric in the position of technical support for low- and medium-voltage projects and the design of busbar trunking systems.
I'm highly specialized in the design of LV/MV switchgear and low-voltage, high-power busbar trunking (<6300A) in substations, commercial buildings and industry facilities. I'm also a professional in AutoCAD programming.

How primary feeder, distribution transformer, fuses and service operate in radial networks
As we already know, distribution transformers step down from the distribution or primary feeder voltage to the utilization voltage. They are connected to the primary feeder, sub-feeders, and laterals through primary fuses or fused cutouts. The primary fuse disconnects its… Read more
