Bunu anlayabilmek i\u00e7in \u0130T\u00dc\u2019den, Bo\u011fazi\u00e7i\u2019nden, Yeditepe\u2019den, Sabanc\u0131\u2019dan hocalara ve adli bili\u015fim uzmanlar\u0131na dan\u0131\u015ft\u0131m.<\/strong>\u00a0Elbette hepsi TE\u0130A\u015e\u2019\u0131n sistemini incelemeden kesin bir cevap veremeyeceklerini belirttiler.

Elimden geldi\u011fince basit bir terc\u00fcmeyle \u015f\u00f6yle a\u00e7\u0131klayabilirim:<\/strong><\/p>\n

B\u00f6yle b\u00fcy\u00fck hacimli bir elektrik sistemini kontrol eden yaz\u0131l\u0131mlara genel olarak\u00a0Merkezi Denetleme Ve Veri Toplama Sistemi (SCADA)<\/strong>deniyor.

Hangi elektrik hatt\u0131nda ne kadar elektrik y\u00fck\u00fc var, nas\u0131l da\u011f\u0131lacak, kabaca bunlar\u0131 tetkik edip ekrana getirirler.<\/strong><\/p>\n

G\u00fcvenlik nedeniyle bu sistemler internete kapal\u0131 devre \u00e7al\u0131\u015f\u0131rlar.<\/strong><\/p>\n

Ama bu demek de\u011fil ki bozguna u\u011frat\u0131lamazlar.<\/p>\n

\u0130kinci neden<\/strong>\u00a0ise, k\u0131sa s\u00fcrede kesintiyi yaratan ne ise halledilmi\u015f olmas\u0131.
