The ABCs of Reliability Aesthetics Service Item Service Benefit External Hardware Inspect Paint Labels Inspect Inspect Minimize corrosion to maintain bushing and tank seals Avoid rust stains Maintain non-corrosive tank for oil reservoir Provide valuable environmental and hazard information 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.

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. 60 60 ielectric integrity is maintained by servicing the oil and 50 D TIME [cycles (60 hertz basis)] 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. 0.6 Dielectric Integrity Service Item Service Benefit Oil Head Gasket Bushings Bushing Gaskets Liner Tank Filter, Replace Inspect Inspect Replace Replace Inspect Maintain dielectric integrity Avoid moisture ingress, maintaining dielectric integrity Avoid external flashover and high radio noise Avoid moisture ingress path Avoid dielectric failure due to moisture Verify tank is maintaining oil reservoir and not leaking 3 Kyle® Distribution Switchgear Service, Our Mission Switchgear Support Group Kyle Distribution Switchgear Service provides our utility customers the finest service on the most technically advanced distribution equipment in the world.
