DELTA3000

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

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 DEL

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

The built-in tracking automatic interference suppression
circuit ensures accurate and reliable test results under
severe electrostatic and electromagnetic interference
conditions. This feature allows the performance of test
measurements in energized switchyards of up to 765 kV.
