MEGGER

Complete Transformer Test Systems

Megger’s multifunction solutions occupy a unique and in-demand space:
Our multifunction systems and van solutions are intuitive with all of the ease of working with individual, dedicated instruments. We deliver this experience through our design philosophy. Rather than producing a single, complex system with afterthought towards rendering it friendly, we uniquely combine several intelligent instruments packaged as a single system. This approach provides all the efficiencies that one would expect from a multifunction solution with all the comfortability and feel of working with a manageable single function instrument. For the user, this translates to a positive and unintimidating testing experience in spite of the comprehensive range of the system’s testing capability.

A transformer test van with fully integrated instruments, accessories and test leads, furthers this concept. All lead management takes place at a smart interface at the back-end of the van. At the heart of the system is a switchbox that serves to reduce the collective sets of test leads from all the individual test instruments to a minimum common set, which:

significantly reduces setup and breakdown time with minimal leads to manage
speeds movement from one electrical test to another
improves safety with less ladder climbs, a common safety ground for all tests, and an intelligent UI to assure focus even if yours wanders
With the transformer test van’s cable reel system, there is also virtually no chance that you forget a lead or pack it in the wrong instrument’s lead bag making it difficult to locate the next time there is need to test.

Megger’s transformer test van significantly improves the bottom line of testing, providing all the conveniences of multifunction testing plus more – with the added benefit that should one instrument require repair, you don’t lose access to the rest of the transformer test van’s comprehensive testing capabilities.

State-of-the-art power transformer testing
TRAX offers a full set of standard and advanced tests for power transformers with several unique and outstanding features:

• WRM at 100 A and 50 V for faster saturation of large or high inductance transformers.
• True dynamic resistance measurement of OLTC (Megger innovation) that accurately resolves diverter resistances and transition times.
• Adaptive demagnetization for the fastest and most efficient demagnetization on the market.

Best-in-class tan delta / power factor testing
Together with TDX 120 TRAX offers the most advanced tan delta /Power factor testing on the market:

• Tan delta / power factor testing at 12 kV and 500 mA for high capacitance tests without the use of an external inductor.
• Individual temperature correction (ITC - Megger innovation) for more accurate insulation properties at reference temp (20 °C) when measuring warm or cold objects
• Voltage dependence detecion (VDD - Megger innovation) to automatically warn if test object shows signs of power factor voltage dependence and a tip-up test should be performed
• Narrowband DFR testing capabilities from 1 - 500 Hz.

Circuit breaker analyzer included
TRAX includes Meggers market leading circuit breaker testing technology and offers, as the only multifunctional test set on the market, the following tests:

• Timing test (O, C, OC, CO & OCO)
• Station voltage
• Pre-insertion resistance (PIR)
• Coil current
• Breaker graphs (timing, voltage, current)

Manual control
TRAX offers full manual control of inputs and outputs which is an unique tool for immediate troubleshooting if standard tests fail. It is also ideal for universities & research institutes that want the best hardware but at the same time want to design their own tests.

• 10 generators & 4+2 measurement channels
• Parameter calculation tool
• Oscilloscope

Power transformer test van
COMPREHENSIVE, PORTABLE TRANSFORMER TESTING

  • Routine and advanced diagnostic tests
  • Centralized control and reporting
  • Two sets of cables (HV and LV) are shared among different instruments
  • Automated test circuit arrangement and switching process
  • Safe operation and user guidance through the tests
  • Easy extraction of mounted instruments for standalone use
Increased transformer test efficiency.
To stream-line your on-site assessment of power transformer condition the Megger transformer test van is equipped with a selection of instruments. It arrives on site ready for action to start testing, to rapidly yield and store results, and it even simplifies packing up for you.

The dedicated transformer test van helps you perform a range of routine electrical tests and advanced diagnostic techniques to international standards. Commissioning testing confirms that the system conforms to the design parameters, while the on-going maintenance tests confirm that no changes are occurring, and confirm the safe uninterrupted operation of the power transformer and substation.
