- Fault location methods:
+ electroacoustic;
+ induction;
+ potential.
- Indication:
+ oscillographic (on screen of graphic liquid-crystal display);
+ aural (on sound in headphones).
- Maximum cable burial depth when locating its track, m – 10;
- Cable track location error (at cable burial depth - 1 m), m, at most, – 0,05.
- Maximum cable burial depth at fault location:
+ by electro-acoustic method, m – 5;
+ by induction method («loop» mode), m – 3;
- Fault location error (cable burial depth - 1 m), m, at most:
+ by electro-acoustic method, m, – ±0,25;
+ by induction method («loop» mode), m – ±1.
