In the power grid of the future, power generation will be decentral. An increasing number of distribution networks are taking green power from PV systems and wind turbines and transporting it in all directions. As a result, we now have a multi-directional flow of energy. Widescale networking of different smart technologies is becoming commonplace.

Modern technology = higher risk

Operators, therefore, need to pay more attention to the protection of their systems. Smart telecontrols, data and communications technology require an increasing number of electronic components. This leads to a greater risk of damage to electronic devices due to

• Lightning interference
• Surges
• Electromagnetic interference
• Arc fault protection system (to the topic)
