PTG2000 Power Generation, Transmission and Grid Modular System consists of equipment that together form a mini power system showing how the power system works from production to consumer. The electric power system has two voltage sources consisting synchronous generator and one from the existing power distribution network. Furthermore, one or more transformers can be used to connect the generator and load points to the mains. The switchgear has dual buses and three feeders for incoming and outgoing lines. The PTG1450 Line Multi Protection Trainer and PTG1455 Differential Relay Module are equipped with the latest ABB protection with great possibilities to perform a wide range of Laboratory experiments.
