ACTION REQUESTED:
title

body
DEPARTMENT: Electric Utility
SUBMITTED BY: Mark Curran, Director
BOARD/COMMISSION REVIEW:
N/A
BACKGROUND:
As part of an efficient and safe electric power distribution and delivery system, a common industry practice is to install switches that allow customers to be connected to one of two or more redundant high voltage feeder lines. The Naperville Electric Utility uses 600-amp, two and three-way air insulated switches to connect customers to multiple primary feeder lines without cross-connecting the feeders to each other. These switches allow utility linemen to quickly isolate problem areas and to restore customer power by connecting them to a different supply line. Additionally, the air switches have replaceable fuses on the load side, to reduce the number of customers affected by outages, and which can be easily, quickly, and safely replaced by utility linemen.

Currently, the Naperville Electric Utility distribution system is comprised of 16 substations and 117 primary feeders. To connect these substations and feeders to customers, the Utility has installed 725, 600-amp manual air switches and 107 automated (DA) air switches, as provided by the S&C Electric Company in Chicago.
