Eagle Eye GFL-1000 Portable DC Ground Fault Locator

Eagle Eye GFL-1000 Portable DC Ground Fault Locator

The Eagle Eye GFL-1000 is a portable ground fault locator designed to identify current leakage faults in DC power systems. The instrument measures grounding resistance and distributed capacitance to help locate faults in electrical circuits where cables experience breakage or grounding loss.

Designed using field experience across DC system environments, the GFL-1000 enables technicians to detect and track grounding faults while systems remain online. The instrument supports troubleshooting and preventative maintenance for DC electrical infrastructure used in industrial, telecommunications, and transportation applications.

Ground Fault Detection Features

• Detects grounding resistance faults up to 1 MΩ
• Measures grounding resistance and distributed capacitance
• Operates on DC systems ranging from 24 to 1000 V
• Selectable testing frequency designed for different system conditions
• Color backlit LCD display for field visibility

Detection Method and System Operation

The GFL-1000 locates ground faults by injecting a signal into the DC system and analyzing resulting current and capacitance characteristics. Based on the distribution capacitance of the circuit, the instrument selects an appropriate output frequency for testing, enabling effective fault detection across a range of DC system configurations.

Typical Applications

• DC power systems in utility infrastructure
• Railway and transit electrical systems
• Telecommunications power equipment
