Major ideology for this proposal used to maintaining and detection of high voltage stress in MV or HV underground cables. The monitoring of UG cables can be done by i2c protocol using embedded technology. Every one kilometer sensor (slaves) is placed to know the information about the voltage stress level. Thus conversely provides the data about the UG cables. All the data are stored in master controller (PIC controller). In case any abnormal voltage disturbance in the UG cable, the correction can be done in input side by using step down transformer. In output side can be controlled by step up transformer. The fault distance can be calculated with the help of the straightforward idea of ohm's law and also the fault location easily identified and corrected in very fast manner by using communication protocol. At the point shortcoming as, low out happens, drop of voltage contingent upon the size of flaw in link, load current fluctuates and refreshed in IOT. © 2020 Elsevier B.V., All rights reserved.
