Transmission lines are vital infrastructure components in the electrical grid, responsible for carrying power over long distances from generation sites to distribution networks. However, not all transmission lines function perfectly; some exhibit leakage, which can have significant implications for efficiency, safety, and the quality of power delivered. Understanding the concept of leaky transmission lines is essential for engineers, utility providers, and consumers alike.

Another vital component, capacitors store and release electrical energy. They are used in various applications, including power supply smoothing, energy storage, and signal coupling in communication systems. Capacitor types, such as electrolytic, ceramic, and tantalum, each have unique characteristics that make them suitable for different functions. In audio systems, capacitors help enhance sound quality by filtering unwanted frequencies, showing their significant role in consumer electronics.

Circuit breakers are essential for protecting the substation and the wider power distribution network from overloads and short circuits. They work by automatically interrupting the electrical flow in the event of a fault, thereby preventing damage to equipment and ensuring safety. Modern substations may employ various types of circuit breakers, such as air-insulated, gas-insulated, or oil-filled breakers, each offering specific advantages depending on the operating environment and design considerations.
