Is temperature measurement important for bus connectors

Accurate temperature measurements are crucial for effective maintenance and safety. This can be achieved by painting, coating, or shrink-wrapping the surface. Non-contact infrared sensors continuously monitor busbar temperature from a safe distance within cabinets, avoiding physical contact or complex insulation requirements. Statistical analysis from electrical utilities worldwide reveals that thermal-related failures account for 30-40% of all high voltage switchgear breakdowns, with average repair costs. A busbar temperature monitoring system is designed to continuously measure and monitor the temperature of busbars within a bus duct. Busbars are critical components that carry substantial electrical currents and are prone to heating, which, if unchecked, can lead to detrimental effects such as. DTSX is a temperature sensor that can provide 24 hours, 365 days monitoring of temperature changes over long distances and wide areas using sensing technology that takes advantage of the characteristics of fiber optic cable. DTXS can be laid out following the path or shape of the object to be. The IEC 61439-1 sets the thermal limit in busbars working at the maximum working load. Here, 140°C (which is 105K over the ambient temperature of 35°C) is the upper safe temperature limit.
