A Reflectometer for Cable Fault Location with Multiple Pulse Reflection Method
نویسنده
چکیده
In this paper, the studies of finding the failure location on a sample cable by using the multiple pulse reflection method and the fault on the results of the measurement have been examined. A pulse generator with amplitude of 12 V and pulse width from 20 ns to 2 us has been designed as a multiple pulse reflection meter. The velocity of reflection pulse is calibrated in embedded system. The SOPC system detects the reflection pulse and measures the time of N times reflection pulses, then judge the fault type and compute the fault distance with corrected speed of pulse developed for measurement of pulse reflection by means of pulse velocity correction and have been examined here.

Power distribution feeders contains many laterals, sub-laterals, different number of circuit line, load taps, balanced and unbalanced load, different type of lines (cable or overhead), different cross-sections and numerous distribution transformers with different capacities. Moreover, the voltage and current are measured only at the beginning of the feeder. Thus, fault location is very complex....

In this paper a novel pulse sequence testing methodology is presented [22] as an alternative to Time Domain Reflectometry (TDR) for transmission line health condition monitoring, faultfinding and location. This scheme uses Pseudo Random Binary Sequence (PRBS) injection for transmission line testing and fault location with cross correlation (CCR) techniques to build a unique response profile, as...

In this paper, a new method is proposed for fault location estimation in overhead-cable multi-section transmission lines. This method takes advantage of synchronized samples gathered from both terminals of the line in the time domain. Because of this, it does not need a filter to extract fundamental frequency of the voltages and currents. Thus, it shows a higher accuracy, since it is not influe...
