K-800 Ground Fault Locator
The K-800 is a professional-grade DC ground fault locator designed for fast, accurate, and reliable detection of ground faults in large-scale DC networks such as substations, telecom power systems, battery banks, solar arrays, railway signaling, and industrial DC control circuits.
It offers deeper detection capability, higher resolution, and improved anti-interference performance compared to the K-3836 / K-3837 / K-3838 models.
Key Features
-
High-precision ground fault locating for complex DC systems
-
Supports live testing — no shutdown required
-
Superior anti-interference capability for noisy HV substations
-
Enhanced sensitivity for long cable circuits and high-resistance faults
-
Quick learning curve with simple, intuitive interface
-
Rugged enclosure for field and industrial environments
How It Works / Overview
The K-800 operates by injecting a tracking signal into the DC distribution network.
Technicians trace cable routes using the handheld receiver, observing variations in signal amplitude and polarity to identify:
-
Fault point distance
-
Exact fault position
-
High-resistance leakage
-
Intermittent or unstable faults
This approach allows technicians to locate faults quickly, safely, and without interrupting normal DC operations.
