is a multi-part international standard for surge arresters – devices that protect electrical equipment from overvoltages (e.g., lightning strikes, switching surges).
Sizing a surge arrester requires balancing normal grid operating limits against transient extreme voltages.
Specialized distribution and transmission line arresters featuring distinct external air gaps, governed by IEC 60099-8 . : Covered natively under the design umbrellas of IEC 60099-4
Surge arresters are critical components in electrical systems, designed to protect equipment from high-voltage transients, such as those caused by lightning or switching events. The IEC 60099 series is the internationally recognized standard for surge arresters, with serving as the key application guide.
