In process engineering plants such as refineries with exposed building parts or extensive water management systems, surge events can cause disastrous consequences: from damage or destruction of expensive components and machines to breakdown of complete automation systems—not including risks to personnel.

Besides these dangerous risks to people and environment, overvoltages are still one of the most common causes of damage in electrical plant engineering. They primarily occur due to lightning strikes or switching operations, but also due to the following causes:

• Electrostatic discharge
• Brush fire of large electric machines
• Fluctuations in power supply
• Ground faults / short circuits
• Triggering fuses
• Parallel installation of energy and information technology control systems
