Temperature Measurement Method for Busbar Trunking in Switchgear
Non-contact infrared temperature sensors are ideal: they can provide an accurate, instant reading of the surface temperature of the conductor, while remaining physically isolated from the voltage it carries. Inside the switchgear cabinets, power is transferred by copper busbars that are bolted. Busbar temperature monitoring represents the most critical parameter in preventing catastrophic switchgear failures. 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. Temperature rise testing is one of the recommendations of IEC 61439; our system for monitoring switchgear and busbars is easily integrated with new installations or retrofitted to existing infrastructure. complex data into clear insights for action, reducing noise and speeding response. Thermal monitoring locations include: Eaton Exertherm CTM solution for MV switchgear.
