Building on Part 1, this session focuses on how Analyze Function operates in real conditions. You’ll watch the Fluke GFL-1500 measure open-circuit voltage, identify voltage-to-ground differences, and estimate ground-fault resistance.
See how entering the number of modules allows the instrument to calculate where the fault is located within the string — a major time-saver for technicians in the field. You’ll also learn how environmental factors like irradiance and temperature can slightly affect the calculated range, and how to interpret that variation correctly.
A must-see for anyone performing accurate PV fault diagnostics and analysis.
