Non-contact infrared sensors continuously monitor busbar temperature from a safe distance within cabinets, avoiding physical contact or complex insulation requirements. They detect early signs of overheating, allowing preventive maintenance. 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 monitoring in high-voltage busbar systems is vital for preventing faults, yet difficult due to electrical hazards, limited accessibility in switchgear cabinets, and interference risks in traditional contact-based methods. Gradual degradation, poor connections, and electrical imbalance. Busbar (copper row) lap surface is the “throat” part of the power transmission and distribution system, and its contact state directly determines the efficiency and safety of power transmission.
