Temperature measurement of copper busbar of high voltage 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. 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. 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. Simulation results allow a set of analyzes, such as the. 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. Due to busbars conducting high currents, small rises in temperature can be indicative of faults.
