### Discussion of a Generalized Monitoring Concept  
The model for calculating the probability of detection (PoD model) was created for each component using the statistical parameters from the previous analyses. Potential sensor distances were calculated using these models, and the required number of sensors was determined. The development and analysis of the models directly validate the conclusions from Section 4.3, stating that installing sensors on the foundation for the novel anchoring is not feasible. The high attenuation led to substantial interference caused by operational noise. Consequently, each anchoring must be monitored with a single sensor, resulting in a total of 24 sensors. In contrast, the tendons, characterized by relatively low attenuation, permit a more extensive sensor range. A 90% detection probability can be achieved at a distance of up to 17.2 m. With the tendon's length in the tower measuring approximately 80 m, a minimum of five sensors is required for effective monitoring. The spectral centroid serves as an additional evaluation criterion for the tendons. A frequency analysis combined signals from wire breaks with various randomly selected operational measurement data, aiming to assess superimposition effects in the frequency range. The intensity of the wire break signals is particularly high at sensors 1-8, resulting in a favorable signal-to-noise ratio. Upon superimposition with operational noise from sensor 3 (transition piece), a discernible shift of the spectral centroid by approximately 3-4 kHz towards higher frequencies was observed. Due to the high attenuation in the anchorages, the authors assumed that the operational noise at the tendon was similar to that at the foundation. Still, clearly, it was not specified during the monitoring. Under this assumption, the evaluation threshold given in Table 1 clearly demonstrates that sensors directly attached to the tendon enable reliable distinction. This finding is particularly significant for the novel anchoring construction, where the direct attachment of sensors to the tendon provides this benefit. A low background noise level was assumed for the PoD model of the tendon. The measurements have shown that the coupling via the anchoring naturally absorbs the noise. However, intermittent contact of the tendons with the tower's inner wall introduces potential influences on signal propagation and possible coupling of operational noise. The PoD models for the foundation with conventional anchoring and the transition piece are presented in Figure 13, focusing on the amplitude feature due to pronounced superimposition from operational noise, as shown through the frequency analysis. Both models rely on measurement data from sensor 24 on the transition piece crossbeam, assuming comparable signal transmission from the tendon to the crossbeam. From a constructive perspective, the number and quality of interfaces are very comparable in both cases. The attenuation through signal transmission is implicitly included in the model by considering measurements from sensor 24 characterizing a local output signal. The values are conservative, accounting for the attenuation of the tendon for a 9 m section. As a result, maximum sensor distances are determined to be 4.0 m for the foundation and 2.7 m for the transition piece. This allows for the coverage of multiple tendons by a single sensor, enabling grouped monitoring in the transverse direction and consequently reducing the number of sensors for wire break detection in the anchoring areas. The anchorages are arranged radially on the foundation and the transition piece, requiring a minimum of seven sensors on the foundation and five sensors on the transition piece based on their respective circumferences of approximately 25.1 m and 11.0 m. The distribution of sensor locations in the anchoring areas is depicted in Figure 14, emphasizing the top views of the entrance at ground level for conventional and novel anchoring (left and middle), as well as the transition piece (right).
