Application Brief
Standardization with Kyle® Type L Reclosers
Results in Economic Savings
Bob Simmons, Field Operations Supervisor, at Illinois
Power states, “We have been a customer for many
years and we have found it cost effective to purchase
Cooper products.”
Recently Illinois Power has initiated a standardization
effort to effectively operate its distribution system,
while providing a high
level of distribution system reliability and holding
down costs. Single-phase
hydraulic reclosers were
an integral factor in the
standardization effort.
"Fuse savings" on the
laterals were achieved
by using single-phase
reclosers throughout the
system. Temporary fault
protection has many
benefits to Illinois Power:
• Increasing overall system reliability by shortening duration of system outage (SAIDI).
• Increasing fault sensitivity by using lower
minimum trip values
(smaller coil sizes)
compared to backup
“We recognized savings when we looked at
our emergency requirements and five-year
change-out maintenance schedule. Ongoing
savings are worthwhile with the L reclosers.”
Bob Simmons,
Field Operations Supervisor,
Illinois Power
Next, Illinois Power evaluated
its system fault devices and
determined that a significant
portion of their 15 kV system
has available fault current
below 4000 Amps. The objective of evaluating cost and
performance resulted in the
standardization of the Type L
recloser, rated for 4000 Amps
interrupting rating for 14.4 kV
systems. The selection of
series coils down to 25 Amps
with an interrupting fault current/series coil ratio of 60 provides ample interrupting ratings for lightly loaded feeders.
The completely self-contained hydraulic mechanism
requires no external AC
power batteries for complete
operating performance.

• Clearing temporary faults has the least amount
of impact to their distribution systems or their
customers as high magnitude faults can be
cleared in 2–3 cycles.
• Simplifying coordination with small downstream
fuses and upline three-phase reclosers.
Simmons comments, “We are
standardizing, centralizing, and
simplifying to make our business better.”
