Read Eaton’s Condition-Based Monitoring of Oil-Insulated, Vacuum Interrupting Single-Phase Reclosers white paper to gain insight on condition-based monitoring techniques that can be applied to oil-insulated, vacuum interrupting single-phase reclosers that can be applied to oil-insulated, vacuum interrupting single-phase reclosers by examining stresses that drive recloser wear-out and the design features that address those stresses.

Excerpt:

Recent surveys show that utilities continue to scrutinize maintenance budgets for sources of operating cost savings. Historically, utilities established time based maintenance
cycles based on their operations experience, operating environment, and manufacturer’s recommendations. Utilities are increasingly deploying condition-based monitoring (CBM) for establishing maintenance cycles for their assets. CBM is considered the most efficient and effective method for users to determine the need for maintenance or replacement of equipment.

This started with transmission assets and is transitioning to equipment installed on distribution systems. Utility interest in CBM for line installed reclosers has increased as the number of installed units and their age increases.

Eaton’s Cooper Power Systems offers a family of reclosers that are elegantly simple yet contain design features that withstand environmental and use stresses, significantly extending condition based maintenance cycles. The purpose of this paper is to provide insight on CBM techniques that can be applied to oil-insulated, vacuum interrupting single-phase reclosers by examining stresses that drive recloser wear-out and the design features that address…>>Read More
