Engineers use this standard to establish maintenance protocols. It details several methods for monitoring arrester health in-service:
The standard covers several types of modern overvoltage protection devices:
Including those with series or parallel gaps rated up to 52 kV.
Detailed comparisons between the old line discharge classes and the new charge-based classification, including simplified estimation methods for switching energies. Why Professionals Use the IEC 60099-5 PDF
Estimating the lightning charge transfer requirements, crucial for lines below 245 kV where Station Light (SL) arresters are common.
