Abstract: We present the results of numerical analysis of normal zone propagation in astack of $YBa 2Cu 3O {7-x}$ coated conductors which imitates a pancake coil.Our main purpose is to determine whether the quench protection quality of suchcoils can be substantially improved by increased contact resistance between thesuperconducting film and the stabilizer. We show that with increased contactresistance the speed of normal zone propagation increases, the detection of anormal zone inside the coil becomes possible earlier, when the peak temperatureinside the normal zone is lower, and stability margins shrink. Thus, increasingcontact resistance may become a viable option for improving the prospects ofcoated conductors for high $T c$ magnets applications.
