Modelová Otázka ID 3458 - 
V elektrické přenosové síti je využíván:
Správná odpověď je: B
Pro přenos elektrické energie na velké vzdálenosti je z nabízených možností nejvhodnější střídavý elektrický proud s harmonickým průběhem. Velkou výhodou střídavého proudu oproti stejnosměrnému jsou v přenosové soustavě nižší ztráty energie, ale také menší potřebná tloušťka vodičů. Napětí střídavého proudu je transformováno dle potřeby; pro dálkový přenos elektrické energie jsou užívána vysoká napětí (až 400 kV), pro přenos elektrické energie těsně před distribucí se užívají napětí menší (např. 22 kV).
