DELTA2000

10 kV Automated Insulation Power Factor Test Set

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 au-

tomatically 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 condi-

tions. This feature allows the performance of test measure-

ments 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 cur-

rent 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.

FEATURES AND BENEFITS

Fully automatic operation eliminates operator error and

reduces testing time.

Simplified operation procedure eliminates the need for

extensive software or hardware setups.

Performs all standard ungrounded-specimen tests (UST)

and grounded-specimen tests (GST), with or without a

guard circuit.

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.

Built-in self diagnostic and calibration check.

The operator has the option of measuring either the

power factor or dissipation factor (tan ∂).
