Selection workflows now place heavier emphasis on maximum residual voltage as the primary parameter for insulation coordination.
The IEC 60099-5 standard is periodically updated to reflect advances in technology, changes in industry practices, and new safety requirements. These updates are crucial for several reasons:

If you work in high-voltage engineering, the string of characters "IEC 60099-5 PDF UPD" likely represents a very specific, slightly frustrating moment in your career. It’s the moment you realize that the standard you’ve been referencing for surge arrester selection and testing has evolved, and you need to catch up.
