Underground Wire Fault Detector Project Report - Free download as PDF In this project, a way for sleuthing underground cable fault distance locator is done.

Block Diagram known KM to cross check the accuracy.

The fault occurring at a distance and respective phase is displayed The project uses the simple concept of OHMs law on the pc interfaced with the microcontroller AT where a low DC voltage is applied at the feeder end with a 12bit ADC interlinked by a low cost-low power through a series resistor.

The current would vary wireless transceiver.

Underground Cable Fault Distance Locator Circuit and Working

The series 3. Fault Location Methods resistor voltage drop changes accordingly which is then fed to an ADC to develop precise digital data which the programmed microcontroller would display the same in Fault location methods can be classified as: Kilo meters.

The project is assembled with a set of resistors representing cable length in KMs and fault A. KM to cross check the accuracy of the same. Online method for underground cable is less than overhead lines.

This is proposed model of underground cable fault distance locator using microcontroller. It is classified in B.

Offline Method: In this method, special instrument four parts—DC power supply part, cable part, controlling is used to test out service of cable in the field. There are part, and display part. DC power supply part consist of two offline methods as following International Journal of Scientific Research in Science, Engineering and Technology ijsrset.

The cable part is denoted by set of resistors along with switches. This part senses the change in current by sensing the voltage drop. Next is controlling part which consists of analog to digital convertor which Figure 2.

Power Supply Diagram receives input from the current sensing circuit, converts this voltage into digital signal and feeds the B. Transformer microcontroller with the signal. The microcontroller also forms part of the controlling unit and makes necessary calculations regarding the distance of the fault.

The microcontroller also drives a relay driver which in turn controls the switching of a set of relays for proper connection of the cable at each phase. The display part consists of the LCD display interfaced to the microcontroller which shows the status of the cable of each phase and the distance of the cable at the phase, in case of any fault.

Algorithm Figure 3. In this pin 0. But these voltages output, displays the fault position. Thus, the AC input Step5: Call delay. This is done by a transformer. Principle of transformer is according to faraday's law o electromagnetic induction.

Power Supply: The power supply circuit consists of programmable Flash memory. The on-chip to capacitor filter the output voltage from rectifier is fed Flash allows the program memory to be reprogrammed to filter to eliminate any AC.

The filtered DC voltage is given to programmer. PSIM is the engine of the simulation environment. PSIM uses a strong algorithm dedicated to electrical circuits piecewise method, generic models and a fixed time-step. The fast simulation allows repetitive simulation runs and significantly shortens the design cycle. PSIM can simulate control circuit in various forms: in analog circuit, s-domain transfer function block diagram, z-domain transfer function block diagram, custom C code, or in Matlab.

For this we use concept of ohms law so that fault location can be detected. McGraw- Hill, A, Sowmya. Suryawanshi R.

Offline method is classified into two methods such as tracer method and terminal method. Tracer Method In this method fault of the cable can be detected by walking on the cable lines. Fault location is denoted from electromagnetic signal or audible signal.

This method is used to find the fault location very accurately. Terminal Method Terminal method is used to detect the location of the fault in a cable from one end or both the ends without tracking. This method is used to find general areas of the fault to accelerate tracking on buried cable.

Underground Cable Fault Distance Locator Circuit The main concept of this project is to find the distance of underground cable fault from the base station in kilometers. In many urban areas, cable fault is a common problem. When a fault occurs due to some reason, the process of fault tracking without knowing the location related to that particular cable is very difficult.

The proposed system is designed to track the exact location of the fault occurred in the cable. In case is there any short circuit occurred from line to ground, then the voltage across series resistor alters accordingly, then it is fed to an analog to digital converter to develop exact data, which the pre programmed microcontroller will display in kilometers.

The proposed system is designed with a set of resistors to signifying the length of a cable in kilometers, and the fault creation is designed with a set of switches at every known kilometer KM to cross check the exactness of the same.This method is used to find general areas of the fault to accelerate tracking on buried cable. Rinse carefully and dry with a clean cloth or kitchen paper. The below figure is a block diagram of underground cable fault distance surveyor.

Short Circuit Fault Short circuit fault can be divided into two types, namely symmetrical and unsymmetrical faults In symmetrical fault, three phases are short circuited in this type of fault. The target of this project is to work out the gap of underground cable fault through base station in kilometers.

Method 2 Circuit by hand on PCB for simple and small circuits : Taking the circuit as reference, draw a basic sketch on copper plate with pencil and then by using a permanent black marker.

When the fault occurs , the process of repairing related to that particular cable is very difficult. Jitendra Pal Singh is pursuing B.

Majorly a supply line can be affected by conditions of over voltage and over current, and also under voltage condition. The voltage drop across the series resistor changes accordingly and this voltage drop is used in detection of fault location in the underground cables.
