DG15M Cable Fault Tester

A multifunctional tester for complex electromagnetic environments. It integrates broken cable location, short circuits, ground leakage currents, and cable routing.

Highlights

In the power-off state, quickly determine the cable break, the distance to the short-circuit fault point and the total cable length
Accurately locate ground leakage faults caused by damaged insulation layers of buried lines (insulation resistance within 0.5 megohms)
Easily detect the path direction and buried depth of underground cables , facilitating construction and maintenance
Unique anti-interference channel uses a high-performance filtering circuit to effectively suppress power-frequency interference. Even in strong interference environments like under high-voltage lines, near transformers, and in cable trenches, the signal remains clear and stable, eliminating noise interference
Waveform comparison: It can simultaneously display and compare the waveforms of “good line” and “fault line”, and intuitively judge the fault type and location through the graphical interface, reducing dependence on operator experience
Manual test mode: supports manual setting of key parameters such as beam speed and gain to meet the in-depth customized testing needs of professional users
Built-in adjustable signal generator (adjustable amplitude, frequency and type) provides the best signal source for various test scenarios
The integrated multimeter function can directly measure voltage, loop resistance, and insulation resistance , allowing for quick on-site screening of line status in one step
