The Illinois Institute of Technology campus uses H&L Instruments fiber optic transceivers, and the company's SCADA networking technology, to ensure a resilient, self-healing, and economical microgrid distribution system that represents a model design for replication in both campus and urban communities scenarios.

This photo shows a typical Model 570 Fiberoptic Transceiver installation at the 1IT campus beside the S&C Electric Vista Switch and SEL 351 Protection System equipment. The IIT campus system reliability is ensured in great part by the H&L Instruments redundant, self-healing fiber optic transceiver technology, which automatically switches to a secondary fiber in half a power cycle (~6 milliseconds) if the primary fiber cable breaks or a node failure occurs.

H&L Instruments newest product is the Model 570X Fiberoptic Gateway, which further enhances SCADA networks by providing seriaI-DNP3 transmission via TCP or UDP over the fiber network. The 570X Fiberoptic Gateway technology eliminates the need for multi-serial conversion equipment, thereby improving reliability and performance.

The following IEEE Electrification article, published in September of 2013, explains the IIT campus design objectives, and the economic benefits of the microgrid comprised of conventional, wind, and solar power sources. The reference on page 44 to ...communication via fiber-optic cables facilitates the coordination between Vista switches emphasizes the important role played by H&L Instruments redundant, self-healing fiberoptic technology in the design of reliable and economical power distribution systems.
