Surge protection and lightning protection
Surge protection refers to the protection of systems and electrical devices against excessively high voltage peaks caused by switching operations and lightning strikes. An effective lightning protection strategy combines internal and external lightning protection. Protect the power supplies, data, and signals in your system. Use the reliable surge protection solutions available in our various product ranges as part of your internal lightning protection strategy.

Protective circuit principle and protection concept
Protective circuit principle and protection concept
You should plan a protection concept for lightning and surge protection so that all cables, devices, and systems are protected.
The protective circuit principle is easy to illustrate:
Draw an imaginary circle around the object you want to protect. Surge protective devices must be installed at all points where cables intersect this circle. This ensures that the area within the protective circuit is protected in such a way that conducted overvoltages are prevented.
When planning the protection concept, consider the following areas of application:
- Power supply
- Measurement and control technology
- Information technology
- Transmitters and receivers
An effective protective circuit helps ensure seamless surge protection.
Surge protection standards
When it comes to surge protection, which standards must be observed?
National and international standards provide a guide to establishing a lightning and surge protection concept as well as the design of the individual protective devices. They differ depending on region and field of application. The overarching standard is lightning protection standard IEC 62305. It describes protective measures against lightning events and an extensive risk analysis with regard to the necessity, scope, and cost-effectiveness of a protection concept.
