Estimating the lightning charge transfer requirements, crucial for lines below 245 kV where Station Light (SL) arresters are common.
Including those with series or parallel gaps rated up to 52 kV. iec 600995 pdf
Guidance on selecting arresters with the appropriate protective level to safeguard insulation. 2. Diagnostic and Condition Monitoring Estimating the lightning charge transfer requirements
The standard covers several types of modern overvoltage protection devices: iec 600995 pdf
While common, the standard notes their limited use for true health diagnosis unless they are modern variants with current amplitude classification. 3. Informative Annexes The standard is rich with supplemental data, including:
