UTEC recently completed design of a fiber optic transmission relaying system that will use SONET compliant OC-3 switches and T1 multiplexers to provide communications for current differential and step distance relays.
The system will provide communications channels for ten sets of current diﬀerential and step distance relays and provide separate voice, SCADA, and RS 232 channels to 27 remote sites. The system will also provide capacity for other utility high speed data requirements.
