Paper format. National Exams,
December 2013 — 07-Elec-B7 Power Systems Engineering. Open-book,
three hours, any non-communicating calculator permitted. Seven problems of equal
value (20 points each); any five constitute a complete paper and only the first
five appearing in the answer book are marked. All seven are solved here,
because the set is a study resource.
