Oct 16, 2020 Preventing an interruption of service. 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 associated distribution transformer from the primary feeder when a transformer fault
