This standard covers the application of gapless metal-oxide, internally gapped, and externally gapped line arresters (EGLA) for three-phase systems over 1 kV.
They called Lucía in reliability. Lucía’s voice on the call was deliberate and patient. "My initial read: acceptable if we tighten our monitoring down to ±0.5°C and add humidity verification probes inside the test fixtures. Also — note the new paragraph about data retention: five years minimum. We need to update our archive policy." iec 600995 pdf upd
