\nVoor beginners is het niet echt nodig om de fysieke betekenis van deze definitie te begrijpen. Het belangrijkste gebruik van deze spanningswaarde in de norm is het bepalen van de grenswaarde van de speling; verwijzend naar Tabel 15 kan de nominale impulsspanningswaarde direct worden bepaald.
De bovenste zin van Tabel 15 geeft aan dat “Apparaten in overspanningscategorie II vallen.”. Als de nominale spanning van het product 220-240 V AC is, wat overeenkomt met de laatste rij waarden in de eerste kolom van Tabel 15, wordt de nominale pulsspanning bepaald op 2500 V.
\n
\nIk moet zeggen dat de overspanningscategorie (OVC) afkomstig is van standaard IEC 60664-1. onderstaande tabel geeft ons een definitie.
