EPS20 Three Phase Transformer
A Three Phase Transformer for studying typical transformers used
in power systems and for use as a step-up or step-down
transformer with the HFT Education Modular Power System
Simulator.
Connections can be made to both the primary and secondary
sides of the transformer using safety sockets on the front panel. A
clear mimic diagram shows the main parts of the transformer.
