now I'm curious, what voltage range do you get with three phase power brought into say a small factory. 480V?
grid is quivering from over use here, voltage is down, every a/c unit ever made is likely running, almost 100 out right now.
another curious question, what electronic parts fail first when exposed to double normal voltage? Rectifiers? In a surge protector it's a MOV, a varistor dies for our sins.
but if no surge protector, what gives out first? As an old Heathkit builder, I wonder, a resistor, a capacitor? or with IC's, is it some new weakness?
