THE ISSUES OF PHILOSOPHY IN RELAY PROTECTION

Енергозбереження. Енергетика. Енергоаудит., 2013
Философия ( греч.) – дословно « любовь к мудрости», изучает наиболее общие принципы реальности. Википедия определяет философию, как науку, изучающую все. Логика и критический анализ являются столпами философского мышления. Почему бы не применить эти атрибуты философии к анализу ситуации в релейной защите – задался вопросом канд. техн.

Substation relay protection

, 2019
Sustav relejne zaštite električnih postrojenja ima za zadatak brzo otkrivanje i selektivno isključivanje pogoĎenih komponenti sustava, čime se šteta svodi na najmanju moguću mjeru, dok ostatku sustava omogućava neometani nastavak pogona. Danas je relejna
