DELTA3000
10 kV Automated Insulation Power Factor Test Set
Two optional high-voltage reference capacitors are
available to allow the user to perform a quick field check
to ensure the DELTA3000 has maintained its calibration. In
addition, an optional 10 nF TTR capacitor is available to
allow the user to perform high-voltage Transformer Turns
Ratio measurements with the DELTA3000.
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.
The Priority Access program provides specific support to
assure full utilization of the Megger DELTA3000. The
purchase of the program entitles the user to 24/7 support
services at an economical cost, with the first year provided
at no charge. (Applies to US market only.)
FEATURES AND BENEFITS
■
Fully automatic operation (stand-alone or remote-
control) with user interface via on-screen customizable
test forms.
■
Integrated PowerDB ONBOARD allows for data analysis
and trending while in the field without the use of an
external computer.
■
Built-in USB port and included USB printer allows for
8.5”x 11” or A4 test forms printing without the use of a
laptop.
■
Built-in capability for storing test results, in an open
XML format, to either internal memory or to an external
USB storage device.
■
Large 8.4” full VGA bright color display.
■ Performs all standard ungrounded-specimen tests (UST)
and grounded-specimen tests (GST), with or without a
guard circuit.
■ Built-in self diagnostic and calibration check.
■ Optional module to perform LV three-phase transformer
turns ratio testing and excitation current up to 500 mA in
accordance with Megger TTR330 product specifications.
■ Utilizing the automatic suppression circuitry achieves
high accuracy measurement under severe electrostatic
and electromagnetic interference conditions.
■ Two-piece design reduces size and weight of the system
and provides easier transportation.
■ The operator has the option of measuring either the
power factor or dissipation factor (tan
∂).
■ Open-ground detector ensures proper grounding before
test.
■ Interlock switches provide operator safety.
■ High accuracy SF6 gas-filled capacitor as internal
reference.
■ Built-in interface to the optional Resonating Inductor
(Cat. No. 670600) to extend the capacitance measuring
range to 1.1 µF at 10 kV.
■ Optional HV TTR capacitor (10 nF) in addition to two
HV reference capacitors (100 pF and 1000 pF) with a 2%
dissipation factor.
■ Optional USB bar code scanner to record and
alphanumeric test identification in the field.
■ Optional Priority Access package with exclusive services
(US market only).
■ Optional Oil Test Cell for testing insulating fluids up
to 10 kV.
■ Optional Calibration Standard verifies proper operation
and accuracy of the test results.
The DELTA3000, available in either 120 or 240 V ac/50 or 60 Hz,
