Surge Arresters and Circuit Breakers in High Voltage Grids and Train Systems
Surge arresters and circuit breakers are vital components in the protection and efficient operation of high voltage grids and train systems. They safeguard the infrastructure against overvoltages and electrical faults, ensuring the stability and reliability of power distribution.
Surge Arresters
Surge arresters protect electrical equipment from overvoltage transients caused by external (lightning) or internal (switching) events. They are critical in high voltage grids and train systems to prevent damage to transformers, capacitors, and other sensitive components.
Circuit Breakers
Circuit breakers serve as the primary protection against short circuits and overloads in electrical systems. They automatically isolate sections of the grid or train system during electrical faults, minimizing damage and preventing widespread outages.
