The Challenge
Developing a method to assess cable insulation integrity under live conditions introduces several real-world challenges. Unlike traditional offline tests that allow controlled, high-voltage spot measurements with all equipment powered down, live environments offer no such isolation. Power cannot be turned off, and loads remain active and variable, making it difficult to define clear test boundaries. Safety regulations may limit access to certain points in the system, and engineers often cannot interact directly with live conductors. Additionally, each installation differs in configuration, loading, and physical layout, making it hard to establish a universal testing framework. There is also no widely accepted standard or benchmark for evaluating insulation health during operation, which complicates both the design and validation of any new approach.
