DELTA2000
DESCRIPTION
The DELTA2000 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.
This set has been designed to provide a comprehensive AC
insulation diagnostic test. Measurements are performed automatically by the DELTA2000, and results are displayed on
a large graphical LCD. 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.
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 operator has the option of storing the test results on
the provided data key, or download directly to a PC or the
included thermal printer. A small printer mounting can be
installed inside the unit’s lid in lieu of the standard printer
that is included. The data key has storage capacity for 127
sets of test results. Information stored on the data key can
be easily retrieved on a PC using the provided software
program and interface box.
In addition to performing insulation power factor tests, the
DELTA2000 can be used for measuring the excitation current of transformer windings.
The Priority Access program provides specific guaranteed
support to assure full utilization of the Megger
DELTA2000. The purchase of the program entitles the user
free services for one year from receipt of the unit.

PowerDB™ Acceptance & Maintenance Test Data
Management Software
The DELTA2000 is controlled and automated by the
PowerDB management system, a powerful software
package providing data management for acceptance and
maintenance testing jobs. Customer/contract information
is quickly sorted and searched. Opening a specific record
shows detailed information such as type of service, order
date, sales contact, and invoice information. Job information can be transferred between field-use databases and a
master database. Job/Device Productivity Reports aid in
bidding future jobs as well as personnel evaluation.
Electrical utilities who have invested in sophisticated Computerized Maintenance Management Systems (CMMS) can
easily link with the PowerDB software because it works
with a number of systems.
The package also provides test documentation and trending, report generation and a number of other optional addons that are described in the Megger PowerDB data sheet
available on our website www.megger.com.
