Comprehensive Guide to IEC 60099-5: Surge Arrester Selection and Application Recommendations

is a technical guide designed to complement IEC 60099-4 (which focuses on metal-oxide surge arresters without gaps).

Older versions may not account for the energy withstand capabilities of modern metal-oxide materials. Using updated guidelines ensures maximum protection for costly assets like transformers. You may have meant: You can view previews,

The primary driver for the update was the shift from "line discharge classes" to a more precise system based on .

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 Older versions may not account for the energy

Applying IEC 60099-5 in practice involves a multi-tiered engineering calculation workflow to ensure protection equipment does not fail thermally or suffer dielectric breakdown under continuous operating stresses.
