DC Trace

DC Trace

SCOPE introduces DC Trace, the most advanced and user friendly DC Earth (Ground) Fault Locator. This portable instrument consisting of Signal Generator & Signal Receiver (DC TraceR) uses latest digital signal processing technology. It’s ability to detect earth faults in live DC system quickly & accurately in online condition greatly relieves the substation maintenance engineers from nightmare of earth leakages & it’s detection.

Its capability to detect the high resistance faults upto 1MΩ, helps to detect fault at incipient stage. Use of two current sensing clamps pinpoint fault quickly by eliminating interference. It is an excellent solution for preventive maintenance & troubleshooting of ground faults. 


  • Touchscreen operation on colour graphical LCD
  • Online fault detection, no shut-down required
  • Signal Generator with adjustable output voltages from 24V to 1000V, suitable for different applications
  • Pinpoints high grounding resistance faults up to 1MΩ
  • Digital Signal Processing Technology for detecting grounding resistance and distributed capacitance
  • 10Hz output frequency on the signal receiver effectively avoids interference from the DC system
  • Frequency Spectrum Analysis for detection of surrounding frequencies
  • A signal Receiver with adjustable sensitivity at different locations of the circuit helps to locate the current leakage quickly
  • Direction (forward/reverse) indication for leakage current helps quick tracing of the faulty grounding path
  • Multiple analysis & indications for easy ground fault identification:
    • Direction of current flow
    • Phase angle difference
    • Comparison of signal strength
  • Detection of complex, multipoint and DC source mixing faults
  • Multiple receivers can work simultaneously with single generator
