TRAX: Redefining Transformer and Substation Test Systems
The Megger TRAX Multifunction Transformer and Substation Test System stands out as a groundbreaking solution for power equipment testing. Designed with innovation as its foundation, TRAX combines portability, flexibility, and robust performance to address the challenging requirements of transformer and substation testing environments. This instrument is more than a collection of measurement tools—it’s a cohesive platform built to streamline every aspect of the work, sparing valuable time while maximizing accuracy and insight. Every detail, from the intuitive inputs and outputs to the integrated software apps, is engineered to benefit the field engineer, ROC specialist, or those involved in power asset management. Testing modern equipment in substations and transformer rooms can be a labor-intensive task, but TRAX’s thoughtful design, rapid setup, and advanced test routines make it a decisively preferred tool for utility companies, service providers, and asset owners worldwide.
Superior User Experience With Innovative Interface Design
A major aspect that elevates the TRAX system above competitors is its dynamic user interface and app-centric workflow. From the moment the engineer engages with the touchscreen display, the focus is on clarity and efficiency. The system boasts clear indicators for cable connections, custom wiring diagrams for every test mode, and step-by-step software applications that guide the user through industry-standard and custom test procedures. Every function is accessible via a highly visual, intuitive menu, significantly reducing the learning curve for new users and minimizing setup time. Particularly valuable during site work, the TRAX’s digital environment enables seamless transitions between different tests, from winding resistance measurements to breaker analysis, ensuring that data acquisition is both quick and reliable.
Leading Applications Across Power Industry Environments
The versatility of the Megger TRAX Multifunction Test System finds its greatest strength in its wide range of targeted applications. Field engineers harness TRAX to perform comprehensive transformer diagnostics, including winding resistance, turns ratio, demagnetization routines, and advanced dynamic resistance tests on OLTCs (On Load Tap Changers). The system is uniquely equipped with 12 kV power factor and tan delta testing, making it indispensable for insulation condition assessment in transformers and high-voltage apparatus. Additionally, TRAX includes powerful functions for circuit breaker timing, station voltage verification, pre-insertion resistance (PIR) testing, and detailed coil current analysis—key tasks for maintaining the reliability of substations. Thanks to its manual control features, TRAX also supports real-time troubleshooting, on-the-spot root cause analysis, and custom testing sequences for research or advanced technical study.
Comprehensive Hardware and Software Integration Features
At the heart of the TRAX system is its ingeniously integrated hardware and software architecture. The hardware includes up to ten precision-controlled generators for AC and DC voltage or current, and six measurement channels for capturing both voltage and current signals in AC or DC. Such flexibility means engineers can simulate real-world operating scenarios, reliably replicate faults, and precisely test the equipment’s behavior under various loads and conditions. Meanwhile, the software complements this hardware with a selection of test apps for each equipment type, fast setup wizards, and a built-in oscilloscope for real-time data monitoring. Its adaptability is further enhanced by features such as an electrical formula calculator, simplifying complex parameter calculations directly at the test site without additional tools.
Advanced Testing Methods and Unique Technologies
A distinguishing trait of Megger TRAX is its embrace of advanced measurement techniques that redefine test quality and depth. For transformer assessment, the system delivers an industry-leading 100 A true DC current with up to 50 V compliance for winding resistance measurements, enabling fast and accurate results even on large units. The adaptive demagnetization algorithm ensures thorough and efficient transformer core demagnetization, critical for achieving reliable post-maintenance test conditions. For turns ratio measurements, TRAX delivers up to 250 V AC, providing precise and stable readings over a wide operational range. Additionally, Megger’s patented technologies for dynamic resistance and temperature correction guarantee data authenticity, accuracy, and actionable insight—vital for predictive maintenance and long-term condition tracking.
Market-leading Circuit Breaker Analysis Technology Included
TRAX comes loaded with Megger’s renowned circuit breaker test technology, effectively replacing the need for separate dedicated test sets. Capabilities cover key breaker test protocols such as opening, closing, and various operational sequences (O, C, OC, CO, OCO), real-time station voltage evaluation, and fast pre-insertion resistance measurement. The system captures and graphs breaker timing, voltage, and current, facilitating powerful diagnostic analysis essential for modern asset life-cycle management. With the flexibility to operate in full manual mode, utility maintenance teams can recreate unusual on-site conditions for troubleshooting or accurately repeat routine tests for quality assurance, training, or regulatory compliance. This makes TRAX a must-have instrument for substations and power plants aiming for highest levels of uptime and reliability.
