Fluke FLK-GFL1500-393FC Offers

The Fluke FLK-GFL1500-393FC helps solar technicians troubleshoot faster, work more safely, and reduce PV system downtime. By combining ground fault locating, non-contact tracing, open-circuit detection, voltage measurement, and clamp current testing in one field-ready kit, it reduces guesswork, minimizes unnecessary disconnections, and supports accurate diagnostics on high-voltage solar installations up to 1500 V DC.

GFL-1500 Solar Ground Fault Locator

• Identify and locate active ground faults anywhere in the DC system with an easy-to-follow traceable signal
• FaultTrack Technology detects active faults and generates a traceable signal through the fault path, enabling technicians to follow that signal from the transmitter
• through the faulted path to the precise point of failure
• Reduce the amount of time it takes to locate active ground faults and decrease your exposure to electrical hazards with non-contact signal tracing
• Includes both a signal tracing receiver and clamp, each suited to different stages of the diagnostic process
• The clamp is useful for identifying the faulted combiner or string without making disconnections, even in noisy environments where signal clarity may be reduced
• Once the affected solar string is identified, the signal tracing receiver or clamp can be used to precisely follow the fault path and pinpoint the issue within the string
• Analyze Function quickly identifies the presence of an active fault and provides key diagnostic details, such as estimated location of the fault based on the number of modules in the string, estimated resistance range and voltage to ground, enabling technicians to assess system status before they start tracing
• Analyze Function guides technicians along the fault path using real-time audio-visual signal feedback, allowing foraccurate and efficient localization of the fault within the array
• Fault Tracing Function helps technicians locate breaks in wiring within isolated strings by routing a traceable signal through the open circuit, giving technicians real-time audiovisual signal feedback to guide them directly to the point of interruption
• Open Circuit Function routes the traceable signal through a healthy string, allowing technicians to identify and confirm string layout, which is especially helpful in complex or undocumented arrays
