Features:

1. The objective of Smart Power System Trainer is to develop a real time automated power system network and control test-bed at the laboratory level to enhance student understanding about power system testing and validation
2. SPS system consists of Generation, Synchronisation, Double Bus Bar, Transmission & Distribution power engineering setups, integrated numeric protection relays for generator protection, synchronisation relay, distance protection, transformer protection, RTUs with Ethernet & RS485/MODBUS ports, touch panel HMIs, supervisory controller / touch panel PC with latest SCADA software, preformed patch cords / cables to integrate seamlessly various parts into single system, aluminum profile tables with under trolleys / drawers etc.
3. Resources needed by respective setups are placed on trolleys below the tables
4. The individual modular flat demo panel setups can also be worked jointly (automated SCADA) or severally (manual experiments) thereby accommodating more student capacity whenever time demands
5. Facilitates easy and safe wiring by students due to use of 4mm sturdy Shrouded banana patch cords for high voltage circuits
6. Student friendly Instructor Guide & Student Workbooks giving detail experiment procedures, wiring schedule & tabular results
