The DGT provides the performance and security essential across the Power Distribution industry
with a fast radio platform necessary for mission-critical applications such as DG interconnection.
It is a wireless solution that enables long range, unlicensed transfer trip signals in 30 msec or less,
allowing fast disconnect of remote distributed generators from the utility power network.
The DGT offers a right balance of speed and range to transfer trip signals and status confirmation,
faster than typical radio communications systems. Combining high data-rate digital transmissions,
with robust frequency hopping technology, the helps ensure.
Distributed Generation Trip Controls (DGT) are wireless communication devices used in applications
that require transferring of trip signals from Power Distribution Utility Substations or Recloser Sites
to multiple (1-7) Distributed Generators interconnected to the distribution grid.
