Hot spots on energized switches are often treated as isolated temperature issues, but in reality, they can be early warning signs of deeper mechanical, environmental, and lubrication-related problems. Left unaddressed, these issues can lead to unreliable switching, increased operating force, longer work windows, and higher risk in the field.
In this webinar, we’ll walk through what hot spots actually signal, the most common causes utilities see in the field, and how to evaluate when an issue can be addressed safely as part of an energized mitigation workflow versus when it truly requires an outage. Attendees will leave with a practical, field-tested framework they can apply immediately to improve reliability, reduce repeat issues, and make more informed maintenance decisions.
Learning Objectives:
- How failed trips and reclose operations affect safety and reliability.
- What stiffened grease, contamination, and sluggish operation can indicate.
- Why a temporary penetrant may not resolve an underlying lubrication problem.
- How to approach lubricant selection for different breaker components.
- Why testing operation after maintenance and recording results matter.
Attendees will gain a clearer understanding of how to interpret hot spots on energized switches and how to respond with practical, repeatable maintenance approaches that reduce risk, downtime, and unnecessary outages.
This is a must-attend event for Substation and circuit breaker maintenance managers, supervisors, and technicians; utility safety managers and specialists; maintenance trainers; and asset reliability engineers. Protection and control technicians and operations supervisors are useful secondary audiences because they work with breaker performance and maintenance planning.. We encourage you to forward this webinar to the relevant executive and training stakeholders on your team.
Time will be dedicated at the end of the discussion to answer live audience questions.
Attendance worth 1 contact hour for certification/CUSP maintenance.
