Symmetric fault — In power engineering, specifically three phase power, a symmetric, symmetrical or balanced fault is a fault which affects each of the three phases equally. In transmission line faults, roughly 5% are symmetric. This is in contrast to an… … Wikipedia
Base (group theory) — Let G be a finite permutation group acting on a set Omega. A sequence :B = [eta 1,eta 2,...,eta k] of k distinct elements of Omega is a base for G if the only element of G which fixes every eta i in B pointwise is the identity element of G.We … Wikipedia
