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.
