High-voltage engineering is a branch of electrical engineering that focuses on the design, testing, and maintenance of systems that operate at high voltages, typically above 1,000 volts. This field is crucial for the transmission and distribution of electrical power, ensuring that electricity can travel long distances efficiently and safely. Professionals in high-voltage engineering work with various components, such as transformers, circuit breakers, and insulators, to manage the risks associated with high voltage. They also conduct tests to ensure that equipment can withstand extreme conditions, helping to prevent failures and maintain a reliable power supply.
