K-3838 Ground Fault Locator
The K-3838 is a high-accuracy DC ground fault locator designed for professional use in telecoms, substations, battery systems, railway signaling, solar DC circuits, and industrial control loops.
It provides deeper detection capability than the 3836/3837 models, offering more precise fault tracing, improved noise immunity, and higher sensitivity to high-resistance leakage faults.
Key Features
-
Locates ground faults in DC systems without shutting down equipment
-
Higher sensitivity for high-resistance or long-distance faults
-
Enhanced anti-interference performance in noisy industrial environments
-
Simple operation — designed for one-technician field testing
-
Lightweight, rugged handheld design
How It Works / Overview
The K-3838 injects a tracking signal into the DC network and detects variations caused by:
-
direct low-resistance faults
-
insulation breakdown
-
moisture-induced leakage
-
partial/intermittent faults
Technicians follow the cable run using the handheld receiver, watching changes in signal amplitude to pinpoint the exact fault location.
This method is safe, non-intrusive, and suitable for live DC troubleshooting.
