Power Utilization Trainer (SMT-EPU-03)
AC and three-phase technology offer a major advantage over DC by allowing electrical power to be generated economically at large power stations located far from consumers. Power is transmitted efficiently at high voltage over long distances with minimal loss, facilitated by transformers. In this laboratory, a three-winding transformer is analyzed, providing different connection options and a variable secondary voltage. The tertiary winding is designed for stabilizing asymmetrical loads with a delta configuration. Overhead lines are primarily used for power transmission, while cables are employed in densely populated areas. Key switching station components like busbars, disconnectors, and circuit breakers are also studied.
