DESCRIPTION
The DELTA3000 is a fully automatic 10 kV insulation
power factor test set designed for condition assessment of
electrical insulation in high voltage apparatus such as
transformers, bushings, circuit breakers, cables, lightning
arresters and rotating machinery. In addition to performing
insulation power factor tests, the DELTA3000 can be used
for measuring the excitation current of transformer
windings.
The DELTA3000 allows for direct data feed into PowerDB
for automatically generating test reports such as table of
contents, data sheets, deficiency and comments r
data can be saved in an XML file with all historical data.
This allows the user to view the previous year’s test sheet
or to trend specific test points. If a user also has a full
license of PowerDB, test sheets can be modified and
downloaded to the instrument to customize the
instrument’s personality and procedures in order to meet
customer needs.
The unit’s intuitive and easy-to-use interface allows the
user to configur

p
®
ased software
b
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 DELTA3000 can be performed in a remote
control manner, via PowerDB. Once testing is complete,
results are easily downloaded to the external PC in an
“open” XML data format. The unit’s internal memory also
maintains historical data-files so that, through interface to
PowerDB, current and past results can be archived,
compared, analyzed, displayed in trend charts, and
compiled into Test Reports.
Control of the DELTA3000 in this remote-control manner
offers the following benefits:
■
Easy to use interface between operator and instrument.
■
Suspect data points are flagged visually using a RED
highlight.
■
Easily recall transformer setups from a custom settings
menu.
■
Quickly download results to the PC for completing a
transformer test report.
With PowerDB’s extensive database capabilities, 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.
For testing companies using PowerDB, customer/contract
information is quickly sorted and searched. Opening a
specific record shows detailed information such as type of
service, order date, sales contact, and invoice information.
Job infor
mation can be transferr
ed between field-use
databases and a master database. Job/Device Productivity
Reports aid in bidding future jobs as well as personnel
evaluation.
The package also provides a number of other optional
add-ons that ar

PowerDB™ ONBOARD Acceptance & Maintenance
Test Data Management Software
The “PowerDB ONBOARD” logo means PowerDB
oftware is running on a computer embedded within
s
the DELTA3000. This powerful feature provides the
DELTA3000 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
or instrument set-up and test operation. Results are
f
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”
or A4 test form can also be printed in the field via an
optional USB printer, and without the use of an external
computer.
