Copper Cable Fault Injection Using Servo-Controlled Resistance

The patent applies the dynamics principle by replacing static fault simulators with dynamic fault injection capabilities. The system uses a fault injection module that can dynamically create and modify fault conditions during cable testing, allowing the fault characteristics to change over time rather than remaining fixed. This enables accurate simulation of real-world dynamic fault conditions while maintaining the ability to adjust fault parameters as needed for different training scenarios.

The patent applies segmentation by dividing the training system into modular components: a portable fault injection module, a cable under test, and testing equipment. This modular architecture allows the system to be transported and deployed in various locations without requiring a fixed laboratory infrastructure, thereby achieving both accuracy and portability simultaneously.

The patent applies parameter changes by incorporating controllable fault parameters such as resistance, capacitance, and inductance that can be dynamically adjusted. The fault injection module can modify these electrical parameters to accurately replicate various real-world fault conditions while maintaining a compact portable form factor, thus achieving both portability and simulation accuracy.

The patent introduces an intermediary fault injection module that sits between the testing equipment and the cable under test. This module creates realistic fault conditions that mimic actual cable failures rather than presenting artificial static configurations. The intermediary translates the high detection precision of sophisticated testing equipment into accurate diagnostic results by presenting genuine fault scenarios that require proper diagnostic procedures.
