Efficient Use of Available Comms Channels Reduces Costs
Appropriate communications channels for protection applications are costly and are often in short supply. Digital multiplexing makes efficient use of available communications channels to reduce costs by limiting the number of independent circuits required.
The benefits of multiplexing digital interfaces into a single digital interface include:
- Leveraging teleprotection channels by combining with digital relay channels
- Avoiding use of additional multiplexing communications equipment
- Long Haul Fiber
Use Multiple Comms Technologies & Mediums to Establish a Common Point-to-Point Comms Path
Substations are sometimes located in hard-toreach places. That can make it difficult to establish a common communications path from one point to another. Using multiple communications technologies and mediums to create an end-to-end channel can solve this problem. Preform a conversion operation between two communications channels to provide one continuous circuit. When done internally at a logic level within one device, this can be accomplished with minimal additional latency.
