The Renewable Shift: Managing New Stressors and Preventing Equipment Failure
As wind and solar generation become major contributors to today’s energy mix, utilities are experiencing new and unexpected challenges in grid reliability. The shift from traditional synchronous generation to renewable sources has altered system dynamics, making the grid more susceptible to voltage disturbances, harmonics, and other power quality issues. These changes introduce electrical and thermal stresses on high-voltage assets—especially transformers, bushings, and switchgear—that were not designed with these conditions in mind.
Harmonics, for example, can accelerate insulation aging, elevate hotspot temperatures, and distort voltage waveforms. These distortions can complicate the interpretation of data from online monitoring systems, often increasing false alarms and obscuring early indicators of failure.
In this webinar you will
- Understand how renewable integration is changing equipment stress profiles and influencing failure rates.
- Learn how online monitoring systems detect early-stage failure modes that traditional maintenance may miss.
- See real-world case studies demonstrating how monitoring improves reliability and prevents catastrophic failures.
