Intelligent Direct Transfer Trip (DTT) Leveraging Cellular Communications
Traditionally, Direct Transfer Trip (DTT) signals are sent between substations and remote distributed generation (DG) sites using leased copper telephone lines. If the DTT communication is interrupted, then these DTT systems automatically disconnect the DG site from the power grid. Madison Gas & Electric and Siemens Digital Grid discuss a recommended approach to providing intelligent DTT signals using redundant cellular communication channels. This webinar will focus on an Intelligent Direct Transfer Trip (DTT) solution using redundant cellular communications being deployed by today’s leading utilities.
