The superconducting DTT magnetic system needs a quench detection systems (QDSs) fast enough to trigger the dumping of the magnetic energy in case of quench and avoid irreversible damage of the cable systems. With this aim, a primary system based on the detection of the resistive voltage associated with the quench offers the best quench detection guarantees. The tokamak environment is affected by several electromagnetic noises during plasma scenarios so that the resistive voltage detection, during normal operation, can be compromised by the presence of large voltages induced by self and mutual magnetic coupling among coils and with plasma or passive elements: the resulting inductive voltages across a TF coil, or part thereof, could be much higher than the quench voltage thresholds. Voltage compensations techniques, therefore, have necessarily to be foreseen in the QDSs conceptual design, to discriminate the resistive component associated with the quench. We present a reconnaissance of all known electromagnetic noises that could affect a TF coils QDS in DTT: this analysis is conducted by means of analytical calculations, made up with the aim to evaluate and have a prevision of the maximum extent of the voltages induced across TF coils and Double Pancakes (DPs) during, in particular, the Single Null (SN) scenario.

超导DTT磁性系统需要足够快速的失超检测系统（QDS），以在发生失超时触发磁能的释放，并避免对电缆系统造成不可逆转的损害。为此，基于与失超相关的电阻电压的检测的主系统可提供最佳的失超检测保证。托卡马克环境在等离子环境中会受到多种电磁噪声的影响，因此，在正常运行期间，由于线圈之间以及与等离子或无源元件之间的自身和相互磁耦合而产生的大电压会损害电阻电压检测： TF线圈或其一部分上的感应电压可能远高于失超电压阈值。因此，电压补偿技术 必须在QDS的概念设计中预见到，以区别与淬火相关的电阻性组件。我们对可能影响DTT中TF线圈QDS的所有已知电磁噪声进行了侦察：此分析是通过分析计算的方式进行的，旨在评估并预先确定跨TF感应的电压的最大范围线圈和双薄煎饼（DP），尤其是在单空（SN）情况下。
