Phasor measurement units are installed at different strategic locations in the power system to acquire the voltages and currents at the buses for executing the required control and protection actions. Emerging methodologies like the wide area protection and wide area monitoring have proved to be promising for detecting abnormalities in the power system. The recent advancement in modern information technology has brought revolutionary changes in the control and protection of power system, which has elevated the reliability as well as the power quality.
This necessitates the incorporation of efficient substation monitoring devices to continuously screen the status of the substation equipment and notify the substation personnel as soon as an abnormality is detected. The over-stressed power system is susceptible to abnormal condition due to failure of equipment in the substations, which in turn hampers the reliability of power transfer. The result of such unprecedented growth is a large interconnection of transmission and distribution lines via substations. The ever-increasing demand for electric power over the last few decades has led to the growth of transmission and distribution system. The transmission and distribution lines are the vital links in the power system that connects the generating station to the consumers. Also, a comparative study establishes the superiority of SVM over ANFIS in identifying the critical fault conditions using thermal imaging.

This novel real-time monitoring of substation equipment overcomes the drawbacks of the conventional methodology of manual inspection done at a periodic interval thereby preventing the electrical assets from failure before any catastrophe would happen. The information based on the output at the SVM/ANFIS classifier is sent to the SMCC where appropriate actions are taken by the substation engineer.
The processing of these is done at the remote terminal unit by extracting the speeded-up robust features and passing the same through trained adaptive neuro fuzzy inference system (ANFIS) and support vector machine (SVM) classifier. This study proposes a novel algorithm for the real-time condition monitoring of substation equipment using thermal images obtained from thermal cameras. The key component of such a digital substation is substation monitoring control center (SMCC). In distribution systems, the conventional substations are getting transformed to digital substations in the light of upcoming advanced technologies. The recent trend of decreasing reliability of the existing power grid due to various kinds of equipment failures at the transmission and distribution level, has led the researchers to develop advanced protection techniques.
