Vibro-Acoustic as a Fast Diagnostic Tool for On Load Tap Changers
The functioning of an On-Load Tap Changer (OLTC) is complex, since a lot of mechanisms are operating at the same time. Classic testing techniques give very little information on mechanical problems occurring inside an OLTC while in service. This presentation shows how the vibroacoustic method is used as a fast diagnosis tool to easily detect mechanical problems in Tap Changers ON-LINE or OFF-LINE, before they create an outage. We will show also how simultaneous correlation of signals recorded by Vibroacoustic, Motor Current and Dynamic Resistance Measurement (DRM) allows a fast understanding of the internal movements of an OLTC. Each of these tests provides a piece of information that creates a complete picture of the OLTC's condition. Finally, we will present a real case showing how the electric utility New Brunswick Power uses this tool to properly adjust an OLTC.

Advanced Field-Testing Technologies for Oil Filled Transformers
The life extension of large power transformers is becoming more and more critical due to the replacement costs, along with extensive lead times for replacements. Unexpected failure can be very costly, not only in terms of replacement but also in unplanned downtime, or in extreme cases, significant damage to other assets affected by catastrophic failure. In this session, we will explore some of the latest testing technologies to better assess the heath of transformers, along with associated apparatuses such as on-load tap changers and bushings, which account for a large percentage of failures.
2:30 pm - 3:15 pm

Leveraging Color-Changing Thermochromics for Electrical Inspections
In industrial electrical systems, intermittent overheating can be difficult to detect. Thermographic inspections can only pick up overtemperature events that are active at the time of the inspection. This means that high temperatures can remain undetected for some time, making them a persistent and unseen fire risk. The only way to determine if your system has intermittent overheating is to monitor your equipment 24/7. Facility managers are turning to thermochromic science for a solution to this problem.
