Every utility and industrial asset owner eventually faces the same question: should we start with handheld partial discharge (PD) detectors for periodic inspections, or invest directly in online PD monitoring systems? Both approaches detect the same underlying phenomenon, but they answer different operational questions, require different budgets, and fit different stages of a condition-based maintenance
