Question 1 of 27070

Periodic testing using a special sensing device may be performed to detect potentially dangerous loose or corroded bus bar and controller connections. What is the name of this testing technology?

🔍 Key Concepts

• Non-contact temperature measurement methods used on electrical equipment • How heat buildup can indicate loose or corroded electrical connections • Typical maintenance tools used for preventive testing of switchboards and bus bars

💭 Think About

• Which of these choices refers to a technology that can "see" temperature differences on electrical components from a distance? • If a connection is loose or corroded, what physical effect happens at that point, and which option is designed to detect that effect? • Which terms in the options sound like established, real-world diagnostic tools used by marine electricians and surveyors?

✅ Before You Answer

• Identify which option clearly relates to temperature/heat imaging rather than sound, vibration, or chemistry. • Eliminate any answer choices that sound made-up or are not commonly found in marine electrical maintenance manuals. • Ask yourself: which method is actually used with a handheld camera-like device to scan bus bars and controllers for hot spots?
