Preventive vs. predictive maintenance, transformer DGA and furan diagnostics, oil testing, infrared thermography, partial discharge monitoring, breaker and relay maintenance, and fleet-wide asset management.
Module 14's commissioning test record becomes this module's zero-hour baseline. Here that baseline gets put to work: dissolved gas analysis and furan trending against a transformer health index, oil quality testing, load-normalized infrared thermography, and online partial discharge monitoring on cables, switchgear, and transformers.
It closes with breaker and microprocessor relay maintenance — including the settings-audit failure mode self-monitoring can't catch — and shows how every condition indicator in this module rolls up into a fleet-wide risk ranking that actually drives capital replacement and maintenance budgets.
