Cable fault location fault location system EPDL

I. Applications: EPDL Cable Fault Locating System Accurately and quickly detect the main insulation fault of power cables with voltage levels of 35kV and below, calibrate the cable length. III. Main technical parameters of the system: 1) Windows operating system, touch operation mode, scientific cable management, real-time report generation; 10 pulses and 10 flashover wave superposition analysis, built-in operating instructions, cable information, measured cases, etc. 2) System functions: fault distance measurement, fault location, propagation speed test, etc. 3) Test methods: low-voltage pulse, flashover method, audio method, acoustic-magnetic synchronization method, valley method, peak method, electromagnetic induction method, etc. 4) Display control: Cable Fault Analyzer: 12-inch industrial-grade integrated machine control, built-in 12V/10Ah DC power supply, can work continuously for 10 hours; the others are controlled by single-chip microcomputer, and pointer meter display. 5) Test range: Test distance: 60km. 6) Measurement accuracy: rough measurement error: ±10m (absolute value) or 1% (relative value), fine measurement error: ±0.2m (fixed point). 7) Sampling frequency: 100MHz, minimum resolution 0.5m (100m/us) 8) Sampling method: automatic continuous sampling, never miss any discharge waveform 9) Low voltage pulse: width: 0.1uS and 2uS amplitude: 100Vpp 10) Output power: impact power: 0～400W 11) Impact high voltage: 0～8/16/32kV three positions 12) Short circuit current: 0～320mA 13) Burn through power: 2048J
