Summary

As emerging technologies reshape asset management, the electrical testing industry stands at a turning point—yet for decades, it has relied on periodic field testing as the backbone of condition assessment and maintenance planning. Tools like power factor or insulation resistance testing, and more recent in-field inspection methods, such as infrared thermography or partial discharge scanning, have helped utilities and industrial operators identify degradation and prevent failures. However, with rising reliability expectations, aging infrastructure, and reduced maintenance windows, the industry is undergoing a major shift—and monitoring technologies are leading the way.

Today’s online monitoring systems—such as Dissolved Gas Analysis (DGA) and Partial Discharge (PD) enhance the effectiveness of offline testing and maintenance.

Learning Objectives:

Asset life cycle, Bathtub Curve, and the role of monitoring.
Understand how online monitoring data can be used to improve maintenance planning, prioritize resources, and determine when to follow routine test intervals or trigger targeted offline testing. For example, a transformer that shows stable online DGA trends might justify normal test intervals, while unexpected gas increases may trigger targeted offline testing.
How can online monitoring provide both immediate alerts and long-term insights for asset management? We will review trending and PRPD patterns (Phase Resolved PD) as an example.
Demonstration of how interpretation of monitoring data, understanding alarm logic threshold settings, and troubleshooting communication or sensor issues will require expanded training. Beyond conventional testing, field technicians will require knowledge of system integration and post-monitoring support.
How monitoring, providing continuous visibility, and offline testing are essential for in-depth diagnostics in maintaining and improving the health of electrical assets.
