Join us for a crucial seminar on contamination-related failures in electrical machine windings, where we will explore how conducting materials, moisture, and environmental factors compromise insulation integrity. Electrical machine windings rely on adequate creepage distances for insulation, making them highly susceptible to failure when exposed to contaminants such as oil, water, or atmospheric dust. These contaminants create conductive paths that can lead to turn-to-turn or ground short circuits through surface tracking.

We will discuss failure mechanisms, early warning signs, and modern insulation advancements, comparing older organic varnish-based insulation with present-day synthetic resin-bonded materials that better resist moisture absorption.

Attendees will learn how to identify carbonized tracking paths, mitigate contamination risks, and implement preventative maintenance strategies to enhance machine reliability. This seminar is essential for engineers, maintenance teams, and reliability professionals looking to improve insulation longevity and prevent costly electrical failures.

Join us for an informative webinar on Thermal Aging of Stator Windings, where we will explore how heat-induced deterioration affects insulation materials over time. All insulating and bracing materials degrade under prolonged exposure to heat, with the rate of deterioration depending on their thermal properties and operating conditions. While properly rated materials ensure gradual aging over a machine’s service life, certain factors can accelerate deterioration and lead to premature failure.

Key topics include:

• Causes of accelerated thermal aging, including overloading, inadequate cooling, over excitation and system voltage imbalance.
• Effects on insulation materials, including discolouration, brittleness, and increased susceptibility to cracking.
• Strategies to minimise thermal degradation, such as optimising cooling systems and maintaining proper operating conditions.

This webinar is essential for engineers, maintenance professionals, and reliability experts seeking to enhance machine lifespan and prevent costly failures.
