Cable length and fault test section
- Single-ended ranging: greater than 120Km
- Sampling frequency: 160MHz, 80MHz, 40MHz, 20MHz, 10MHz, 5MHz, 2.5MHz
- Pulse amplitude: not less than 120V at 50Ω
- Pulse width: 0.2μs and 2μs
- Single-ended test blind zone of the host: less than 2m; no blind zone for double-ended testing
- Host length measurement error: 1‰～2‰
- Reading resolution: V/2f (V = wave propagation speed in cable (m/μs), f = sampling frequency (MHz)); e.g., for oil-impregnated paper cable with V=160m/μs and f=160MHz sampling, the reading resolution is 160/(2×160)=0.5m
- Three-wave comparison function
- Pre-set wave propagation speeds for 5 cable media: oil-impregnated paper: 160m/μs, cross-linked: 172m/μs, PVC: 184m/μs, non-dripping: 160m/μs, coaxial cable: 196m/μs, plus customizable media
- Automatic analysis function: automatically analyze low-voltage and high-voltage pulse test waveforms, and automatically identify whether the fault point breaks down during fault testing
- Sampling methods: normal trigger mode, full-automatic trigger mode, current sampling
