wire Expo 2024 Update: Wildfire Prevention and Control for Power Lines

Rising global temperatures, prolonged drought seasons, and increased wind intensity have heightened the likelihood of catastrophic wildfires, which pose a significant threat to forests and grassland areas. Climate change has made wildfire prevention and disaster mitigation in specific regions a critical issue. wire Expo 2024 is known from statistics that about 3% of wildfires are caused by faulty power transmission lines.

Wildfires caused by transmission lines typically occur when trees fall and break the cables. Other failure scenarios include tree branches making contact with two cables, causing an arc, or the cables touching each other or aging equipment leading to sparks and arcs. Therefore, regular preventive maintenance of equipment near power lines is essential.

Unfortunately, detection efforts are not always successful. Many fault currents are so small they are nearly undetectable. Reports suggest that 30% to 50% of high-impedance faults go undetected.

Most current power distribution systems rely on overcurrent protection devices such as relays, reclosers, and fuses, which often fail to trigger in the event of high-impedance faults. However, looking ahead, power grids must support emerging and future applications while providing more refined control capabilities.

As countries increasingly focus on the electrification of residential, industrial, and transportation infrastructures, while simultaneously promoting the use of renewable energy, the traditional power grid is becoming a public focal point. wire Expo 2024 believes that as smart grids continue to expand, traditional grid equipment will see higher utilization rates.
