DESCRIPTION
The new DELTA4000 Series is a fully automatic 12 kV
insulation power factor/dissipation factor (tan∂) 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
DELTA4000 Series can be used to measure the excitation
current of transformer windings as well as to perform
automatic tip-up tests and HV turns-ratio testing (an optional
TTR Capacitor is available).
The test set is designed to provide a comprehensive AC
insulation diagnostic test. The high power variable frequency
design generates its own test signal independent of line
frequency quality and the hardware design uses the latest
technology available for digital filtering of the response signal.
As a result, the DELTA4000 Series produces reliable results and
stable readings in the shortest time with the highest accuracy,
even in high interference substations.
The DELTA4000 Series operates with PowerDB software for
automatic testing and reporting or with Delta Control software
for real-time manual testing.
Measurements include voltage, current, power (loss), tan delta,
power factor and capacitance. The test results are automatically
stored in the computer and can also be downloaded directly to
USB storage or a printer.
DELTA4110 test set is to be used with an external computer
(not included) while the DELTA4310 test set comes with an
onboard computer.

FEATURES AND BENEFITS
Industry-Leading Performance and Accuracy
n
Generates its own test signal – resulting in accurate and
clean measurements even in the most severe conditions and
in the event power is required from a portable generator.
n
High noise suppression and advanced signal acquisition
circuitry can handle up to 15 mA interference current or
a signal to noise ratio of up to 1:20 resulting in extremely
accurate and clean measurements even in the most severe
conditions.
n
Industry leading frequency range (1-500Hz) reveals
details in the insulation characteristics that are not possible
to detect with other test sets.
n
Intelligent temperature correction (patent pending)
allows the user to estimate the actual temperature
dependence of the test object by measuring tan delta over
a frequency range. Mathematically calculating accurate
individual temperature correction results in a more accurate
measurement of the insulating material’s condition.
n
Automatic voltage dependence detection (patent
pending) Various high voltage components may have a
voltage dependence where tip-up testing is recommended
(i.e. the dissipation factor is pending test voltage). The
DELTA4000 Series has a patented method for detecting
voltage dependence and gives the user an alarm, suggesting
additional tests should be performed at different voltage
levels.
n
Fast test time - Dynamic noise suppression minimizes
actual test time.
Industry’s Lightest and Most Rugged
n
Industry’s lightest two-piece design, weighing
14 kg + 22 kg saves on effort, space, and shipping costs.
n
Designed for various work environments: in the field; in
a test van; in a manufacturing facility; or in a repair facility.
n
Units have performed successful testing in the world’s
most extreme conditions including: high temperatures,
low temperatures, high elevations, high noise, and high
humidity.
Software Package — PowerDB Advanced
n
Automatic and manual operation – provides fully
automatic operation for tan delta as well as excitation
current and tip-up testing. The user simply selects the test
object and the unit will automatically run the complete test
and report the results back to the test form. The DELTA4000
Series can also be used with Delta Control software in a
manual testing mode, where the operator has full control to
set the test parameters including the possibility to manually
adjust the output voltage and measure output current and
otuput voltage continuously.
n
Easy to save and retrieve data – information will be saved
in an XML file with all historical data. This allows the user to
view previous year’s test sheet or trend specific test points.

12 kV Insulation Diagnostic System
n
Simple, intuitive, easy-to-use interface between operator
and instrument.
n
Suspect data points are flagged visually with a red
highlight.
n
Capability to trend a specific asset over time.
n
Easily recall transformer setups from the settings menu.
n
Ability to interface with other transformer test units
such as MLR10 (leakage reactance, capacitance banks),
TTR-series (transformer turns ratio), MTO210 (winding
resistance), MIT/S1-series (DC insulation), MCT-series
(CT measurements).
Optional Database Software - PowerDB Pro
A comprehensive Acceptance and Maintenance Test
Data Management Software and database that allows you
synchronize information from all of your different types of
instruments into a single database, trend test results to similar
equipment and the ability to design or modify test forms.
n
Easily import your historical data points even from other
manufacturers’ databases.
n
Analysis and trending - As an immediate on-site
assessment the user can compare the latest measurements
with stored data and see how the insulation values
may have changed over time (trending). Comparison of
measurements captured at different voltages and different
frequencies can also be observed. Pass/Fail criteria can
be set to immediately identify a possible problem in your
insulation.
