Why would excessive demand in some parts of South Africa’s electricity grid cause a national blackout and not just a blackout in that area, though? Asked about this, director of EE Publishers and electricity expert Chris Yelland explained that it is the very safety features built into electricity equipment to prevent catastrophic failure that would lead to a blackout.
