An Insight on the IEC 61400-24 Ed2: Lightning Protection of Wind Turbines

The 2010 and first edition of the standard IEC 61400-24, Wind Generator Systems - Part 24 Lightning Protection was a technical success in terms of offering a balanced recommendation for wind turbine overvoltage and lightning protection design; indeed it was an attempt to reflect the technical expertise and maturity of the industry. Since then, the wind power industry has further developed towards even larger wind turbines and into a by far mature industry. This publication is an informative manuscript of the current 2018 draft (FDIS approved 25$^{th}$ of January 2019), which intends to upscale the 2010 edition into a sophisticated standard, with informative and normative annexes. In fact, this new revision reflects an improved technical experience and expertise in the complex topic of overvoltage and lightning protection of wind turbines.
