In recent days, power systems are very complicated to deal with load requires raises and environmental check curbs the network. With the development of urban scale and creation of energy infrastructure, more cities build underground cables to substitute overhead lines from the view point of environment and safety. But it is facing few troubles like installation cost and fault area detection. Finding the precise spot of the error is tougher. In our proposed project, our objective is to improve the trustworthiness of a distribution system and accurate recognition of a faulted location and time of fault. In this work, the three phase voltage and current were monitored. It is IOT based technique where we collect the database and utilize it for monitoring purpose. If the error is located precisely is updated in cloud to facilitate the delay in recovery time reduction. The fault location is displayed through LCD. In addition, it also displays the voltage value at faulty cable and the current consumption through the line is displayed and monitored.
