Surge Protection to BS EN/IEC 62305 Unit 7: Introduction to lightning protection system design
This unit will explore BS EN 62305 Part 3, methods of external lightning protection and isolated systems vs. non-isolated systems. Good surge protection measures must be accompanied by the correct lightning protection system (LPS) with good earthing. This unit covers the basic design parameters and concepts of LPS design based on BS EN 62305 Part 3.
