What is one key component of transmission systems modeled in LMS Substation 2-2?

Transformers are a crucial component of transmission systems modeled in LMS Substation 2-2 because they are essential for the regulation and transformation of voltage levels within the electrical power grid. In transmission systems, transformers play a vital role in stepping up voltage for efficient long-distance power transmission, minimizing energy losses due to resistance in the wires. Additionally, they are used to step down voltage levels at substations to make electricity suitable for distribution to homes and businesses.

Other components such as light switches, outlets, and network routers do not directly pertain to the transmission of high-voltage electrical energy over long distances. Light switches and outlets are more associated with the electrical installations in buildings, facilitating the use of electrical devices rather than the transmission and management of high-power networks. Network routers deal with data communication and networking, which, while important in different contexts, are not directly relevant to the physical and operational aspects of transmission systems modeled in electrical engineering software like LMS Substation 2-2.
