1) Motor power & conductor size: first calculate line current for a 100 kW load. For a balanced three-phase circuit, P=1.732IUcosφ。 From the three-phase power formula, line current I=P/1.732Ucosφ where P is power, U is line voltage (380 V three-phase), cosφis the power factor (typically 0.8). Line current for a 100 kW load: I=P/1.732Ucosφ=100000/1.732*380*0...
