Surge arrester solutions, products and services

Medium- and high-voltage surge arresters for the safe and reliable protection of electrical equipment.

Surge arresters are essential in safeguarding valuable electrical equipment from overvoltage incidents, such as those caused by lightning strikes, switching operations, or other transient events. By effectively diverting surge currents, these devices protect transformers, circuit breakers, generators, motors, capacitors, traction vehicles, bushings, and complete switchgear installations from potential damage. Siemens Energy surge arresters stand out for their superior quality, extended service life, and reliability across diverse operating conditions worldwide. Our products not only adhere to international standards but also undergo rigorous certified quality management processes, ensuring optimal safety and performance.

Since 1925, Siemens Energy has been a leader in designing and manufacturing medium- and high-voltage surge arresters for a broad spectrum of standard and specialized applications.

Surge arresters operate by diverting excess voltage away from sensitive electrical equipment during transient overvoltage events. They use nonlinear resistive elements that remain inactive during normal operation but become highly conductive when voltage surges occur, safely channeling the surge current to the ground.

This protective action prevents insulation breakdown, equipment damage, and service interruptions, thereby enhancing system reliability and reducing maintenance costs.

All Siemens Energy surge arresters are subject to certified quality management and comply with international standards. Our surge arresters are absolutely reliable and characterized by easy installation, low maintenance costs, and an extremely long operating life.
