Megger TTRU1-BASIC Offers

Specially designed for single-phase source and measurement, this handheld transformer turns ratiometer uses turns ratio, routine polarity validation, and TTR excitation current testing to locate problems such as defects and failures, requiring minimal input from users. Furthermore, users can organize and export readable results by email, Microsoft Excel export, or an optional USB printer (sold separately).

Minimize training duration with the intuitive full-color Hi bright LCD user interface, rotary knob for function selection, and automatic results storage. Obtain accurate results with the easy-to-follow setup. In addition, when the batteries need recharging, plug them into any standard USB wall charger or connect them to your PC.

Features

  • Single phase source and measurement for single phase, three phase, and instrument transformer testing: Turns ratio, excitation current, and polarity up to 37.5 V induced
  • Accuracy guaranteed from -4 to 122°F (-20 to 50°C)
  • Excitation current: Included with the TTR test, the excitation current test is extremely useful in locating problems such as defects in magnetic core balance, magnetic core structure, shifting windings, failures in the turn-to-turn insulation, or problems in tap changers
  • TTR Turns ratio testing: When compared to other single phase turns ratio test instruments, this device is easier to use as you don't need to know the proper test voltage to obtain a valid test result
  • Additive/subtractive polarity recognition: Polarity recognition provides confidence in transformer results by performing vector group validation during every test
  • Pass/fail ratio evaluation
  • Calculated ratio with percent error (optional pass/fail display)
  • Uses the latest technological advancements, providing safe, repeatable, and reliable results
  • Results on-screen show if the connected distribution transformer is additive or subtractive
  • Rotary knob for function selection: TTR, settings, info (BASIC/ADV results export)
  • Instrument self-check
  • Full colour Hi-bright LCD: Onscreen vectors and connection diagrams
  • Auto screen dimming and power off
  • Easily manage data with custom transformer entry, auto-saving, and USB export
  • Automatic results storage: Microsoft Excel® export, USB drive save and export or USB printer (sold separately)
