PowerDB™ ONBOARD Acceptance & Maintenance
Test Data Management Software (Model TTR330
only)
The “PowerDB ONBOARD” logo means PowerDB software
is running on a computer embedded within the TTR330.
This powerful feature provides the TTR330 with
a common “User Interface” to minimize operator training
and provides a seamless interface to the full PowerDB
(PC version) application.
Easy-to-read on-screen test forms provide the user interface
for instrument set-up and test operation. Results are
displayed against pass/fail nameplate limits and can be
stored (either internally or to a USB storage device) in an
open XML data format.
The ONBOARD software also maintains a historical data
file so that, while in the field, current and past results can
be analyzed, compared, and displayed in trend charts
without the need of an external computer. An 8.5” x 11”
test form can also be printed in the field via an optional
USB printer, and without the use of an external computer.
Built-in Memory
The TTRs come equipped with sufficient internal memory
to store test results. The outcome of the results are based
on the model:
TTR310: stores up to 200 three-phase data sets in the field
for later retrieval. Test results can be printed on an optional
printer (using thermal spool paper) whenever a hard copy
is desired, or the data can be downloaded to a PC for
archiving, analysis, trending, and/or printing. The system
software allows entry of the transformer alphanumeric
serial number, transformer type and tap information for
each test performed.
TTR320: stores up to 100,000 data sets in the field for
later retrieval. Test results can be printed on an optional
printer (using thermal spool paper) whenever a hard copy
is desired, or the data can later be downloaded to a PC for
archiving, analysis, trending, and/or printing. Identification
of individual test readings is also easily done. The system
software allows entry of the transformer alphanumeric
serial number, transformer type and tap information for
each test performed.
TTR330: stores up to 100,000 data sets in the field for later
retrieval. Test results can be printed on an optional in-lid
printer (using 8.5” x 11” thermal paper) whenever a hard
copy is desired, or the data can later be downloaded to
a PC for archiving, analysis and/or printing. Identification
of individual test readings is also easily done. The system
software allows entry of the transformer alphanumeric
serial number, transformer type and tap information for
each test performed.

PowerDB LITE™ Acceptance & Maintenance
Test Data Management Software
All four units in the TTR300 Series come complete, at no
extra charge, with PowerDB LITE (a new powerful PC
Windows
® based software program). PowerDB LITE allows
the operator to completely program a test routine, in
advance, for a transformer, save it under the transformer ID
number, and then recall it in the future as required.
Testing on the TTRs can be performed in a remote control
manner, via PowerDB LITE. Once testing is complete on
all of the instruments, results are easily downloaded to the
external PC in an “open” XML data format. The instruments’
internal memory also maintains historical data-files so that,
through interface to PowerDB LITE, current and past results
can be archived, compared, analyzed, displayed in trend
charts, and compiled into Test Reports.
Control of the TTRs in this remote-control manner offers
the following benefits:
n Easy to use interface between operator and instrument.
n Problems such as PASS/FAIL are flagged visually using a
RED highlight.
n Easily recall transformer setups from a custom settings
menu.
n Quickly download results to the PC for completing a
transformer test report.
PowerDB™ (full version) Acceptance &
Maintenance Test Data Management Software
As an enhancement over the PowerDB LITE software
(described above), a powerful “full version” PowerDB
software is also available on the TTR300 Series as an
option. PowerDB LITE and the internal architecture of
the TTR Series has a seamless interface to the full version
PowerDB, PC based software application.
Multiple data files (from multiple instruments) can
automatically be fed to PowerDB in order to generate
comprehensive asset analysis in the form of Reports
containing table of contents, test data sheets, commentary,
and deficiency summaries.
Electrical utilities who have invested in sophisticated
Computerized Maintenance Management Systems (CMMS)
can easily link with the PowerDB software because it
works with a number of systems.
