Description
The presentation introduces actual quenches of HTS coils due to conductor degradation caused by thermal stress and electromagnetic force. Such a degradation leads to an irrecoverable thermal runaway, resulting in a catastrophic damage on the coil. NI method is a promising to protect HTS coils. The applicability of the method to pancake-winding and layer-winding is examined with experimental and simulated results. Based on those results, the HTS winding method strategies in the light of protection is discussed.
