DELTA3000
10 kV Automated Insulation Power Factor Test Set
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 reports. All
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 configure test sheets and pop-up test procedures. A
QWERTY keyboard makes it simple for entering all
nameplate and location information. USB drive support is
also included in the unit with two exposed USB ports.
The test set is designed to provide a comprehensive AC
insulation diagnostic test. Measurements are performed
automatically by the DELTA3000, and results are displayed
on a large 8.4” full VGA bright color display. Measured
quantities include voltage, current, power (loss), power
factor and capacitance. The operator has the option of
correcting the current and loss readings to their 2.5 kV
or 10 kV equivalents. Information can be downloaded
directly to a PC or USB flash device, allowing the user to
store up to 100,000 data sets. Printing is done via a
second USB port directly to a USB thermal paper printer
(included) allowing the user to print full-size test forms
in either 8.5” x 11” or A4 size, without the use of an
external laptop.
