🔍 Key Concepts

• Insulation failure causes in electrical machinery • Effect of mechanical stress vs. temperature on insulation • How vibration and operating conditions impact windings and insulation

💭 Think About

• Which of these conditions is most likely to cause physical or mechanical damage to insulation over a long time? • Think about how each option would realistically affect the winding insulation in a motor or generator. • Which condition is commonly associated with loosening, chafing, or cracking of insulation rather than just heating or cooling effects?

✅ Before You Answer

• Identify which choices mainly affect temperature vs. mechanical stress. • Consider which condition could cause rubbing, abrasion, or cracking of insulation over time. • Eliminate any choice that is essentially a normal or even gentle operating condition for electrical machinery.
