Normal zone propagation velocity (NZPV) under fast current rise is a major parameter for resistive type Fault Current Limiters design. We studied quench currents and NZPV under fast current change in several samples of multifilament superconducting wires with highly resistive matrix. All samples demonstrated sufficient scattering of quench currents along samples. Different parts of a sample quench at different times. Depend on current rise rate different modes of quench development have been observed. We present and discuss experimental data about quench development under fast current rise in different samples with non-uniformities along their length.
