Correlation between quench pressure and normal zone voltage observed in the QUELL experiment
An interesting correlation between the quench pressure and the generated power was observed in the quench runs of the QUELL experiment. The experimental results indicate that the instantaneous values of the quench pressure and power generated by the normal zone are linearly correlated during the quench propagation. For quenches with constant operating current, the linear correlation holds for quench pressure and the normal zone resistance or voltage. This correlation can be used to improve the accuracy of the quench detection systems based on voltage taps. It could be also a useful tool for the validation of numerical codes for quench propagation. (C) 2001 Elsevier Science Ltd. All rights reserved.
