Description

Test distance:
 4m~40kmTest precision:Error is no more than 1m @ measuring range < 1km.Relative error is no more than 0.5% @ measuring range > 1 km.Pulse amplitude:no less than 250V @ 50ΩPulse width: 0.2μs, 2μs, 4μsSampling frequency:48MHz, 24MHz, 12MHz, 6MHzSystem Error:10cmReading Frequency:
 V/2f V is the electric wave's propagation velocity  in the cable (m/μs). f is sampling frequency (MHz). For example the oil-paper cable's propagation velocity is V=160m/μs, f=40MHz sampling, the reading frequency is 160/(2×40)=2m.Presetting 5 types electric wave's propagation velocity of cable medium:Oil-paper: 160m/μsXLPE: 172m/μsPVC: 184m/μsRubber Cables for Coal Mine: 100m/μsOthers non-power cable's propagation velocity of electric wave are settable. (Medium is at user's option)Sampling:Current sampling method.Power Supply:Power frequency or build-in rechargeable battery.Power frequency:AC 220V±10%, frequency 50Hz±5%, 24 hours continuously working.Battery:4 hours continuously working.Working temperature:-10ºC~50ºCOversize:(L×W×H)  330×230×150mmWeight:3kg.
SXDL-330D Digital Cable Fault Locator
It's used to locate the power cable insulated fault point, route, depth accurately.Features: High pointing sensitivity. Digital displaying the distance between the faults locating and sensor probe.To touch the sensor probe on fault cable or its near cable, the fault distance and direction could be displayed accurately. Easy to operate.Compact designation, portable. Specification:Digital display distance:Max. 500m, Min. 0.1m.Rough test error:is less than 10%, locating error is 0.Electromagnetic channel gain:>110dB (300 thousand times)Electromagnetic channel receiver sensitivity:<5μVAudio channel frequency amplifier gain:
 120dB  1 million times when SNR (Signal to Noise Ratio) is @ 4:1.50Hz power frequency inhibition degree >40dB (100 times) Audio & electric synchronous display:when do the locating test on site , the digital screen to repeat counting one time under the shocking of electromagnetic which formed by pulse high voltage. And to display the fault distance or fully lighted (500m). The high impedance earphone could detect the seismic wave generated by impulsive discharging breakdown.To change the sound wave sensor probe to the 15KHz electromagnetic one, it could be used as accurate cable route and depth detecting test.Power supply:6V maintenance-free battery 1.2AH.Power consumption:<120mA (0.7W)Working temperature:-10ºC~+50ºC RH 80%.Please contact us by email for further information.
Warranty: One year quality guarantee after shipment.
