High Voltage Engineering is a branch of electrical engineering that focuses on the design, testing, and maintenance of electrical systems operating at high voltages. These systems are crucial for the transmission of electricity over long distances, ensuring efficient power delivery from power plants to substations and ultimately to consumers. Professionals in this field work with equipment such as transformers, circuit breakers, and insulators to ensure safety and reliability. They also conduct tests to prevent electrical failures and to comply with safety standards, making high voltage systems safe for public use and minimizing the risk of electrical hazards.
