We present an inductive analysis of a variety of YBCO coated conductors, based on complementary measurements of a.c.-susceptibility and d.c.-magnetization. The study addresses dissipation mechanisms associated with the grain boundary networks. We show that a.c.-susceptibility measurements are uniquely qualified to identify dissipative contributions from micro structurally inhomogeneous grain boundary networks.
