IOT BASED FAULT DETECTION OF UNDERGROUND CABLES THROUGH NODE MCU MODULE

Abstract : In the downtowns, underground cables are used rather than of overhead transmission lines. It is hard to go through the specific spot of the shortcomings. As India become prominent as a progression country, civilized field is too boosting every day. The underground lines are beat under the same circumstances its uses is additionally growing a result of its clear advantages such as lower line losses, lower maintenance cost and they are less powerless to the effects of serious climate. As it isn't clear it move extreme to identify propel area of the shortcoming. In this proposed work we are trying to rectify this problem by proposing a method which is good enough to the digital world. In this paper we have used IOT based technique with Google database for the fault detection with the help of Node MCU Wifi Module. It is totally based on IOT. We used here Node MCU which connects arduino sensors to Internet.We had created a Hot spot through router for communication. We connected each MCU Module with transformer and used Google data base to checking the status of transformers. The accuracy and efficiency of our proposed method is more as compare to the other techniques.

 EXISTING SYSTEM :

 ? The IoT allows objects to be sensed or controlled remotely across existing network infrastructure, creating opportunities for more direct integration of the physical world into computer-based systems, and resulting in improved efficiency, accuracy and economic benefit in addition to reduced human intervention. ? Due to safety reasons and high power requirements in densely populated areas, use of underground cable has seen a sharp hike. ? This paper deals with the method to locate faults and identify the phase line in damaged cables.

 DISADVANTAGE :

 ? In this paper we have study few techniques to minimize the various problems related to the underground cables but these techniques are not very efficient to detect the problem. ? The call for consistent assistance has caused the improvement of procedure of discovering issues. ? To decide the area of the issue, a heartbeat is useful to the transmission line. Contingent upon the greatness and the stage point, we can settle on the situation of the deficit.

 PROPOSED SYSTEM :

 • The proposed system is an IoT enabled underground cable fault detection system. • The power supply is provided using step-down transformer, rectifier, and regulator. • The current sensing circuit of the cable provides the magnitude of voltage drop across the resistors to the microcontroller and based on the voltage the fault distance is located.

 ADVANTAGE :

 ? The benefits of accurate location of fault are fast repair to revive back the power system, it improves the system performance, it reduce the operating expense and the time to locate the faults in the field. ? Developing efficient scheduling techniques for charging and discharging of electric vehicles can potentially lead to reduce emissions, shave peak load, and increase the used percentage of generated renewable. ? It also uses the surveillance data to predict future activities to be prepared in advance for a more convenient, comfortable, secure, and efficient living environment.
