The Maintenance of Isolated Phase Bus Duct Systems
Service Approaches to maintenance of Isolated Phase Bus Duct (IPBD) systems are not maintenance-free. Often, plant managers will make an incorrect assumption that IPB systems are self-maintained with little human intervention needed. However, IPB systems should be treated with utmost importance, being inspected, cleaned, monitored and maintained on a regular basis for optimal performance.
Typical service approaches to maintenance of IPB systems include:
Cleaning bus walls, equipment and insulators, inside and out
Removal of debris or other loose material from the bus enclosure
Replacing insulators that are damaged or aged
Re-silvering of plated terminals
Verifying ground connections
There are several critical components of IPB systems that must be inspected regularly and maintained proactively. These components include:
Termination assemblies / Expansion joints (including flex connectors and bellows)
