In this introduction to the GFL-1500’s key features, you’ll learn about its three core functions — Analyze, Fault, and Map — and how they work together for fast PV ground-fault detection. The tutorial explains what each mode measures, when to use it, and how results flow logically from one mode to the next.
You’ll understand the basic logic of testing, from initial voltage analysis to fault tracing and final array mapping. Each section builds a foundation for later, more advanced functions demonstrated in subsequent videos.
