IEC 60099-5 is a widely adopted international standard that covers the requirements for surge arresters used in electrical power systems. Surge arresters are essential devices that protect electrical equipment from voltage surges and overvoltages caused by lightning strikes, switching operations, or other external factors. The standard provides guidelines for the design, testing, and application of surge arresters to ensure their safe and reliable operation. If you have landed on this article, you
Surge arresters - Part 5: Selection and application recommendations
You can download the IEC 60099-5 PDF from the official IEC website or other authorized sources.
This standard covers the application of gapless metal-oxide, internally gapped, and externally gapped line arresters (EGLA) for three-phase systems over 1 kV. Information on evaluating the health of arresters through
: Annex J provides guidance on managing and replacing legacy Silicon Carbide (SiC) gapped arresters. Essential Annexes for Selection
System grounding determines TOV traits. For solidly grounded networks, a single phase-to-earth fault elevates the healthy phases by a factor of roughly 1.4 (Earth Fault Factor). In isolated or resonant-grounded systems, this factor increases up to 1.73 (full line-to-line voltage). The selected arrester must possess a TOV capability curve that safely envelopes the system's predicted fault durations. Step 3: Energy and Charge Absorption Sizing
