TRAX

Transformer and Substation Test System

DESCRIPTION

TRAX is a multi-function test system for transformer substation

testing. The test system replaces numerous individual testing devices

which makes testing with TRAX a time saving and cost effective al-

ternative to conventional measurements using separate instruments.

TRAX is a unique test system for testing power, distribution and

instrument transformers, as well as a variety of other substation

components. Providing up to 800 A (TRAX 279/280) and 2200 V

(2000A and 12kV with accessories) with a frequency range adjust-

able from 5 Hz (1 Hz with tan delta unit) to 500 Hz, TRAX can be

used with an integrated touch screen or external computer device

with web browser.

Variable levels of voltage and current can be generated and meas-

ured with high precision, allowing TRAX to be used for a wide range

of applications such as turns ratio, excitation current, winding and

contact resistance, impedance, tan delta/power factor testing and

various primary tests for LV, MV and HV electrical apparatus includ-

ing but not limited to:

 Power & distribution transformers

 Instrument transformers

 Bushings

 LV, MV and HV circuit-breakers

 Busbars

 Protection relays

 Grounding systems

TRAX is designed to be a complete solution in transformer testing.

With its 4800 VA power capability it is a high efficiency, high ac-

curacy and excellent performance transformer test system.

▪Replaces need for multiple test sets

▪Saves time by eliminating need for

multiple instruments learning

▪User-friendly interface reduces training

and testing time

▪Portable and compact system components

for easy shipping

▪“State of the art” measurement methods

for advanced diagnostic testing

Test capability

 Winding resistance measurements

 Adaptive algorithm for optimized transformer

demagnetization

 True dynamic resistance measurements on load tap-

changers

 250 V transformer turns ratio measurements

 12kV dissipation factor and capacitance testing features

The user interface allows fully manual control where the user de-

fines a specific test setup. Alternatively, a variety of individual instru-

ments/apps are available to perform automated testing procedures

such as winding resistance, turns ratio, impedance measurements,

relay testing, circuit breaker analysis and more. The tests can be

organized and reported as separate tests or as a combined full set of

test results for the same asset.

The compact, light-weight design, only 26 kg (TRAX 220), allows

shipment in its transportation case within the limits of check-in lug-

gage (32 kg)

USER INTERFACE

TRAX user interface architecture is based on a number of individual

instruments/apps where only the necessary functionality is displayed

by default. For manual testing a generic instrument is available

where the user selects output, measurement inputs and how the

data should be processed.

For testing complete components (e.g. power transformers),

measurement results from multiple instruments can be collected and

presented in one report.

Derating at lower mains voltage

TRAX specification is valid at 230-240 V mains voltage. Output

power is decreased at lower mains voltages.

Derating at high ambient temperature

TRAX specification is valid at 23 ±5°C. Max output current times

will be reduced when using TRAX in high ambient temperature.

Derating at lower frequencies

TRAX voltage output specification is at 50 Hz. Maximum voltage

output at lower frequencies is limited by the transformer. Derating

is linear with frequency and max voltage output at 5 Hz is 10% of

rated output.
