Utilizarea principal\u0103 a acestei valori de tensiune \u00een standard este de a determina valoarea limit\u0103 a jocului; cu referire la Tabelul 15, valoarea nominal\u0103 a tensiunii de impuls poate fi determinat\u0103 direct.
Fraza de sus a tabelului 15 indic\u0103 faptul c\u0103 \u201eAparatele sunt \u00een categoria II de supratensiune\u201d. Dac\u0103 tensiunea nominal\u0103 a produsului este AC220-240V, corespunz\u0103toare ultimului r\u00e2nd de valori din prima coloan\u0103 a tabelului 15, tensiunea nominal\u0103 a impulsului este determinat\u0103 a fi 2500V.
\n
\nTrebuie s\u0103 spun c\u0103 categoria de supratensiune (OVC) provine din standardul IEC 60664-1. tabelul de mai jos da-ne o definitie.
