Introduction to Condition Monitoring of Electrical Systems

Primarily, any electrical system is an assemblage of various electrical components which are interconnected in a specified manner to perform a specialized function. An electric system can be as simple as a torch on one hand and it can be as abstruse as a spacecraft, on the other. Detailed coverage of all these electrical systems is beyond the purview of this book and hence, a pragmatic review has been made to put together developments related to monitoring techniques of electrical power transmission systems here. This system performs a distinguishing role of ensuring reliable power supply for the utilization by consumers for various applications. The preponderance of faults can be minimized by monitoring certain critical parameters and predicting a fault before it is going to actually happen. In this chapter, an electric power transmission system is branched into Power Transformers, Transmission Lines, Power Transmission Towers and Protective Relays. The primarily focus has been laid to highlight perspective view on the techniques which assist in the development of health prognosis-based (or condition-based) maintenance tools and practices to safeguard the health of these systems in large interest of utilities.
