DGT Distributed Generation Trip
Control System
Chapter 1: Introduction
GE Consumer & Industrial

Introduction
Overview
The DGT Distributed Generation Control System is a wireless communication system
designed to transfer Trip Status signals between a Utility’s substation or recloser site and
Distributed Generation locations. The DGT system supports point to multipoint
communication over distances up to 30 miles and accommodates up to 6 Distributed
Generation locations. There are three main products in a DGT System, the DGT-U, DGT-D
and DGT-R
DGT-U is installed by a Utility at the substation or recloser. It transfers trip signals to
remote DG sites and receives status notification back from each, after a trip operation has
been completed.
DGT-R is a repeater unit installed by the Utility at or near the Utility substation, to
coordinate wireless communication between the DGT-U/DGT-R and the DGT-D(s).
DGT-D is installed at the Distributed Generation site. It receives the trip signal over-the-air
from the DGT-U and outputs the status to the user’s breaker device. The DGT-D also
accepts a connection from the user’s breaker equipment that confirms the trip status back
to the DGT-U.
At the core of all DGT units is a wireless DGT transceiver. The DGT transceivers are
frequency hopping; spread spectrum radios designed for license-free operation in the 902-
928 ISM band. The 902-928 ISM band is license-free throughout North America. The DGT
transceivers employ the latest Digital Signal Processing (DSP) technology to provide highly
reliable long distance communication.
Cautions and warnings
Before attempting to install or use this device, it is imperative that all caution and danger
indicators in this manual are reviewed to help prevent personal injury, equipment damage,
or downtime. The following icons are used to indicate notes, cautions, and dangers.

OVERVIEW CHAPTER 1: INTRODUCTION
Figure 1-1: Note icons used in the documentation
The standard note icon emphasizes a specific point or indicates minor problems that may
occur if instructions are not properly followed.
The caution icon indicates that possible damage to equipment or data may occur if
instructions are not properly followed.
The danger icon provides users with a warning about the possibility of serious or fatal
injury to themselves or others.
Description of DGT system operation
Figure 1-2: Typical DGT system
In Figure 2, DGT-U units installed at the Utility Substation and Recloser sites continuously
monitor the trip status and transmit that status every 28 to 56 milliseconds to DGT-D units
installed at the Distributed Generation sites. At the DGT-D locations the trip status is wired
into breaker device. An auxiliary contact from the breaker is wired back into the DGT-D.
The DGT-D units continuously monitor the status of the auxiliary contact and transmit that
status every 28-56 milliseconds back to the DGT-U units constantly confirming current
status. All communication is coordinated through the DGT-R Unit in order to achieve
maximum range.
If a trip condition is detected by the Utility’s equipment, the trip status is energized at the
DGT-U. When the DGT-D units receive the energized trip status, the output status will
disconnect the Breaker device at the Distributed Generation site. The status of auxiliary
contact from the breaker is also energized and transmitted back to the DGT-U thereby
confirming that the Trip has occurred.

CHAPTER 1: INTRODUCTION OVERVIEW
DGT DISTRIBUTED GENERATION TRIP CONTROL SYSTEM – INSTRUCTION MANUAL 1–3
The entire round trip time from trip initiation at the substation into the DGT-U to
confirmation from the DGT-D occurs in under 150 milliseconds. The integrity of the Trip
Status state is maintained through the use of a 32-bit CRC calculation. The CRC prevents
the erroneous or malicious manipulation of the Trip Status so that only true data is acted
upon. Additional security precautions ensure that only authorized DGT-D devices are able
to wireless achieve association with a Utility’s DGT-U and DGT-R devices, so that the
integrity of each DGT system is maintained.
Description of the DGT system units
The DGT-U, DGT-R and DGT-D, are completely packaged units that includes the
appropriate DGT radio transceiver, power supply, necessary input and output terminations,
antenna jumper cable and lightning protection contained in a weather resistant, pad
lockable enclosure. The only connections required are for primary power, the external
antenna cable, and wiring to the external equipment. All of these wiring connections are
made within the enclosure leaving no connections exposed to weather. DGT units are
designed to be installed in wall-mount or pole-mount configurations. All DGT components
are housed in a NEMA-approved enclosure measuring 13.75 inches high x 11.85 inches
wide x 6.5 inches deep (35cm x 30.1cm x 16.5cm).
There are internal variations in the components contained in a DGT-U, DGT-D or DGT-R.
These variations are shown in Figures 3 through 5

MECHANICAL INSTALLATION CHAPTER 2: INSTALLATION
Installation Considerations
For a successful installation, careful thought must be given to selecting the proper site for
the DGT-D and its antenna system. The location must be able to support antenna
mounting at a height and in a direction that provides an unobstructed radio signal
transmission path to associated DGT sites.
The antenna must aim at the antenna located at your Utility’s DGT-R. The Utility will
provide you with the direction and coordinates to aim the antenna. In addition, the
antenna must be at a suitable height to achieve radio association with the Utility’s
equipment. DGT-D equipment is offered with a number of standard options for antenna
feedline lengths. Select the feedline length necessary to connect the Yagi antenna to the
DGT Unit.
Radio signals travel primarily by line-of-sight, and obstructions between the transmitting
and receiving devices will affect system performance. If you are not familiar with the
effects of terrain and other obstructions on radio transmission, please contact Multilin for
information on arranging a Radio Path Analysis or Site Survey. In addition, the information
below will provide helpful background.
TERRAIN AND SIGNAL STRENGTH
A line-of-sight transmission path between the DGT-D sites is highly desirable and provides
the most reliable communications link. A line-of-sight path is achieved by mounting the
antenna on a tower, pole or other elevated structure that raises it to a height sufficient to
clear surrounding terrain and other obstructions.
The importance of a clear transmission path relates closely to the distance between the
DGT-U and the Utility’s DGT-R. If that distance is limited, for example up to 3 miles (4.8 km),
then some obstructions in the communications path can usually be tolerated with minimal
impact. For longer distances, any substantial obstruction in the communications path
could compromise performance or block communications entirely
CONDUCTING A SITE SURVEY
There must be no doubt about the radio path and antenna height needed for your DGT site
to associate with other DGT stations. Planning and testing is necessary before a
permanent installation is begun. This is done through a path analysis and site survey
conducted by a qualified professional. A site survey gathers actual site information and
summarizes the installation factors specific to a given site. A computer path analysis
based upon the latitude and longitude coordinates of the DGT site assesses factors such
as terrain, distance, transmitter power, and receiver sensitivity, which are necessary to
predict the performance of the DGT installation.
Mounting the enclosure
There are two basic mounting arrangements for the DGT: wall mount or pole mount.
Methods for mounting the unit in both of these configurations follow. When planning the
installation, refer to the Dimensions section above, which shows the mounting dimensions
of the DGT Assembly.
The steps below describe mounting of the DGT unit to a wall or other flat surface. Ordinary
wood screws (with flat washers) can be used for mounting to a wooden surface. If it is to be
mounted to a drywall, masonry or other non-wooden surface, suitable fasteners will be
required that can support the weight of the unit.
WALL MOUNTING
To wall mount the unit, follow these instructions
1. Hold the unit up to the wall in the desired mounting position. Have an assistant mark
the four mounting holes (see Dimensions section above) with a pencil or marker.

CHAPTER 2: INSTALLATION MECHANICAL INSTALLATION
DGT DISTRIBUTED GENERATION TRIP CONTROL SYSTEM – INSTRUCTION MANUAL 2–13
2. Prepare the mounting surface for the fasteners to be used. (If using lag screws, a small
pilot hole at each mark will allow easier starting of the screw.)
3. Insert the 4 mounting screws and tighten them securely. Do not over-tighten.
POLE MOUNTING
Standard pole mounting requires the use of two pole-mount adapters (P/N 82-1743A01).
These brackets must first be bolted to the DGT enclosure. The complete assembly can then
be mounted to a wooden utility pole with two lag screws or with two long bolts that extend
through the pole. (Threaded rod can also be used for through-the-pole mounting.) In either
case, it is important to use flat washers with the attaching hardware (fasteners are not
supplied).
To pole mount the unit, follow these instructions:
1. Attach the two pole-mount adapter brackets to the DGT enclosure with four 10-32
screws. The screws must be no longer than 3/8" (9.5 mm). Longer screws will damage
the enclosure
2. With the help of an assistant, position the DGT enclosure on the pole at the desired
mounting point.
3. Install the attaching hardware (with flat washers) in the center hole of the two
brackets.
4. Tighten the fasteners securely, but do not over-tighten.
