This is a major selection parameter. The standard includes Annex F, which provides typical maximum residual voltages to help you choose the right rating. iec 60099-5 pdf free download
Distinguishing between atmospheric (lightning), switching, and temporary overvoltages. A step-by-step flowchart to determine the rated voltage
IEC 60099-5 is part of the International Electrotechnical Commission (IEC) series of standards for surge arresters. The standard provides guidelines for the selection, application, and maintenance of surge arresters used in power systems to protect against overvoltages caused by lightning, switching operations, or other disturbances. or other disturbances.
