How Do You Spell Reliability?
The
ABC s of Power Distribution Reliability
Reliability
It’s not just a catch-phrase. It’s a
commitment to a superior level of service. It’s the key to
pleased customers, business opportunities, strategic
growth, and satisfied regulatory agencies. It’s what makes
you a trusted power supplier.
What if there was a way to ensure premium reliability,
guarantee continued TCC coordination, and provide optimal
recloser mechanical operation? What if this assurance
required only a minimal investment? There is a way to
realize optimal system reliability, and it doesn’t involve
making a purchase. The secret is simply performing
scheduled maintenance on your Kyle® recloser.
The Kyle reclosers that you already own are the best
choice for providing reliable power distribution. Kyle
quality, backed by over a half century experience as an
industry leader in distribution switchgear, means that your
system is using the most dependable products on the market.
Preserving optimal performance is easy: simply follow the
recloser maintenance guidelines recommended by Cooper
Power Systems.
The system reliability that your Kyle recloser provides, from
TCC coordination to mechanical reliability, is guaranteed by
keeping its components in prime condition. As with any
mechanical device, repeated use takes a toll on even the
best system. Regular maintenance preserves reliability of
operation at peak efficiency, even during peak load demand
periods, and protects system uptime. And uninterrupted
service means a better financial bottom line.
Regular maintenance will guarantee decades of reliable
service from your Kyle distribution switchgear.
You have already made a capital investment in superior
products for reliable outage management. Make sure you
collect the full dividends on that wise investment. Keep
your distribution switchgear operating with the reliability
that you and your customers depend on.
The Kyle reclosers that you already own are an important
part of your commitment to reliability. Establishing and
following a regular maintenance routine will guarantee
decades of reliable service from your Kyle distribution
switchgear. You’ve already made the best decision for
reliability, power quality, and efficiency. Protecting your
investment is the next smart choice.

Routine maintenance provides optimal operation.
Routine maintenance is as easy as ABC. Simple inspections and basic care will keep your Kyle distribution switchgear
operating at its prime. Proper maintenance includes the following basics: filtering or replacing the oil, and replacing the
bushings gaskets, the head gasket, the series coil gasket, and the tank liner. For best performance reliability, Kyle also
recommends inspecting all the components and the mechanism. Complete your maintenance program with a thorough test
plan. Follow these ABC s of proper recloser maintenance to ensure your power distribution system’s optimal reliability.
A
esthetic concerns include hardware corrosion and paint scratches.
Neglect of the exterior could lead to compromising the seal of the
bushings and tank. During regular maintenance is an ideal time to verify
that the non-PCB and hazard labels are still readable by the operating
crews. Replace illegible labels.
B
oost mechanical reliability to ensure that the equipment
itself is operating at peak levels. Mechanical components do exhibit wear
after years of service and should be replaced as needed. Inspect the
mechanism for proper operation to confirm correct tripping and closing.
For oil interrupters, check moving and stationary interrupting contacts for
erosion. If the contact surface shows wear, the part should be replaced. If
the movable contact is replaced, the corresponding stationary contact
should also be replaced to avoid excessive wear on the new moving
contact. For vacuum interrupters, verify contact wear by the scribe mark
wear indicator or by actual measurement of contact erosion. Check
counters for proper alignment and operation to assure accurate system
and maintenance planning information.
It’s as easy as ABC to maintain your power distribution system’s optimal reliability. Contact your
Cooper Power Systems Representative for additional information about maintenance and parts specials.

inspecting the dielectric components on a regular basis. Avoid moisture
ingress and oil degradation through the replacement of fiber liners and
inspection of bushings, bushing gaskets, and tank head gaskets. Fiber
liners retain moisture and should be replaced with every oil change.
Cracked or chipped bushings lead to external flashovers, resulting in
increased damage and system outages. Regular care easily prevents
these problems.

reclosers. The series coil and its gaskets, the pump piston, and the oil all play important roles in the TCC timing and
operation of the recloser. Neglecting these components will prevent proper system coordination and service reliability.
Keep your system well coordinated to avoid lost crew time locating and troubleshooting faulted areas.
