    Y\u0131ld\u0131r\u0131mdan korunma denildi\u011finde akla ilk olarak paratoner sistemleri gelir. Ancak burada \u00f6nemli bir detay vard\u0131r:<\/span><\/p>\n <\/span>\n

    Paratoner yaln\u0131zca binay\u0131 korur, cihazlar\u0131 de\u011fil.<\/strong><\/span><\/p>\n <\/span>\n

    Do\u011fru Parafudr Se\u00e7imi Nas\u0131l Yap\u0131l\u0131r?<\/span><\/h2>\n <\/span>\n

      Parafudr \u00d6ncesi Otomatik Sigorta Neden \u00d6nemlidir?<\/span><\/h2>\n <\/span>\n

      Parafudr sistemlerinde s\u0131k yap\u0131lan hatalardan biri, \u00f6n koruma eleman\u0131n\u0131n ihmal edilmesidir.<\/span><\/p>\n <\/span>\n

        Etkili bir koruma i\u00e7in \u015fu \u00fc\u00e7l\u00fc birlikte uygulanmal\u0131d\u0131r:<\/span>
