Q&A
Q&A: Guardians of Power - Understanding High Voltage Surge Arresters
Q1: What is a high voltage surge arrester and why is it critically important?
A1: A high voltage surge arrester is an electrical device designed to protect power systems and equipment from voltage spikes, or surges, caused by lightning strikes, switching operations, or other disturbances. These devices act as a shield, redirecting excess voltage safely to the ground, thus preserving the integrity of electrical components and ensuring the reliable operation of power systems.
Q2: How do surge arresters function in real-time situations?
A2: Surge arresters operate by remaining non-conductive during normal voltage conditions. When an overvoltage event occurs, the arrester’s resistance drops dramatically, allowing it to conduct the surge current safely away from critical components. Essentially, they become temporary pathways for excess electricity, diverting it and preventing damage.
