A low-voltage surge arrester (LVSA) is an electrical device designed to protect low-voltage electrical systems and equipment from voltage surges and transient overvoltages. Lightning strikes, switching operations , electrostatic discharges, or other transient events, they can all results in overvoltages and damage the power systems.
Why should we use a low voltage surge arrester?
• For Protection: Protect equipment from damage.
• Prevents Fire Hazards: Low-voltage surges will lead to overheating, insulation breakdown, and even electrical fires.
• Reduce Maintenance Costs: Installing LV surge arresters minimizes unexpected damages, saving money in the long run.
• Improves System Reliability: Surge arresters ensure continuous operation by preventing surge-induced disruptions.
• Extends Equipment Lifespan: Metal oxide surge arrester protect insulation and electrical system, prolonging device longevity.
