Condition diagnostics of energized electrical equipment: case studies

Thermal Imaging: Just a Note, Not the Whole Tune: Preventing Electrical Devices from Thermal Damage by Using Highly Certified Thermal Monitoring Devices

“…Continuous thermal monitoring offers substantial benefits when compared with methods providing data collected at discrete, infrequent periods. The ability to determine the equipment condition from real-time data has been proposed in many instances [3], [4]. The efficacy of determining the condition is highly correlated with the quality and quantity of data available.…”

“…Although some wireless technologies can accomplish this [3], [4], circuit breaker interchangeability and servicing is poorly accommodated to the point of being impractical. As a proxy to mounting directly on the circuit breaker, sensors mounted on the pressure connections between the primary disconnect and the connecting bus, as described in the "Thermal Monitoring Technologies" section and shown in Figure 5, are ideal and will be discussed in detail; however, other configurations are possible depending on the equipment construction.…”
