What term is used to describe localized areas of higher temperatures in electrical equipment?

The term "hot spots" refers to localized areas of higher temperatures within electrical equipment. These regions can develop due to various factors such as increased electrical resistance, poor connections, or inadequate cooling. Hot spots are significant because they can indicate potential failure points in the electrical system, leading to overheating or even catastrophic failure if not addressed. Monitoring and managing hot spots is crucial for maintaining the safety and reliability of electrical equipment, as they can pose risks for both equipment integrity and personnel safety. Understanding the concept of hot spots allows operators to take proactive measures in maintenance and operational protocols, ensuring efficient and safe electrical operations.
