In recent years Direct Transfer Trip (DTT) over commercial cellular communication network is drawing more attention as alternative to fiber and private copper line due to its lower cost and availability. This abstract investigates the cellular based DTT topologies, key components, and overall system architectures. In addition, a commercial solution has also been commissioned and being evaluated at EPRI laboratory. DTT trip times are measured under various operating conditions. Finally, selected utility pilot projects are listed to provide the technology adoption landscape.
