Through Faults Causing Mechanical Failure in Transformers
Mechanical failures involve physical displacement or damage of parts within a transformer, and happen for several reasons, including but not limited to transportation, seismic activity, improper synchronizing, switching, and through faults. In this presentation we will define a through fault, discuss through fault monitoring, and how we detect mechanical damage to the transformer due to through faults.

The Critical Role of Transformer Monitoring in Today's Transformer Supply Chain Issues
With supply chain constraints and aging electrical infrastructure, transformer reliability is more critical than ever. This webinar explores how transformer monitoring helps utilities and industrial operators extend asset life, reduce unexpected failures, and maintain grid stability.
Recent CIGRE Technical Brochure TB 939 (September 2024) analyzed 425,000+ transformer-years of operation, revealing that windings (44%), bushings (25%), and tap changers (21%) are the primary failure points. The data confirms that time-based maintenance is ineffective for substation transformers—maintenance should instead be condition-based, using diagnostic measurements and online monitoring.
The webinar will discuss implementing online monitoring systems for the three highest-risk components: main tank active parts, bushings, and OLTCs. These systems provide near real-time technical assessments, enabling fact-based maintenance priorities rather than reactive approaches.
Key takeaways include technical fleet assessment from a criticality perspective, understanding current transformer conditions, and establishing maintenance priorities based on actual component risk rather than assumptions.
