Substations play a crucial role in power delivery systems, <br />ensuring the safe and reliable distribution of electricity from generation facilities to end-users. <br />They serve as vital nodes in the energy infrastructure, facilitating the efficient transmission and <br />distribution of electrical power. Substations provide several key functions that contribute to <br />maintaining the stability and integrity of the power grid such as voltage regulation and <br />transformation, operational switching, monitoring and control, fault isolation, and equipment <br />protection. <br />
