Product Detail

Functional Features

New monitoring methods: high-frequency digital signal spectrum comprehensive analysis method and dual end measurement method;

Fault location: Using the principle of traveling wave distance measurement, precise fault location can be achieved, with a fault distance measurement accuracy of ± 2.5 meters;

Fault line selection: Using the principle of traveling wave line selection, fault circuit line selection is carried out for cable insulation;

Circulation monitoring: Real time monitoring of the insulation condition of the outer sheath of the line. By using digital spectrum analysis methods, the capacitive current, resistive current, and fault arc current of the cable are calculated separately, and the circulation curve is drawn. Fault alarms are given for cable lines with abnormal outer sheath insulation;

Fault warning: three-level warning based on cable operation status.
