Megger TTRU1-ADV Offers

Power through electromechanical transformer testings with this handheld transformer turns ratiometer guided by color-coded leads, clamps, and customizable on-screen vectors while ensuring that the testing parameters match the transformer's nameplate. Use customizable vector lists for data storage on frequently tested transformers, simplifying the selection process for common transformer configurations and results interpretations. Furthermore, users can organize and export readable results by email, PowerDB, 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 and perform over 1000 turn ratio tests on a single charge of a NiMH AA battery. 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 62.5 V induced, ±0.05% accuracy
  • Accuracy guaranteed from -4 to 122°F (-20 to 50°C)
  • Go/No Go transformer testing: Short circuit, open circuit, and inductance winding tests provides confidence that the high and low side of a distribution transformer does not have easily identifiable failures
  • Go/No go testing identifies the electromechanical source of the problem: Short circuit on primary or secondary, open circuit on primary or secondary, loss of inductance (issues with transformer core)
  • Combined with turns ratio, polarity, and excitation tests, the go/no go test can provide additional information to determine required maintenance activities of transformers
  • Custom vector list/voltages: Increase efficiency by saving up to 10 commonly used transformer vectors and voltages found in the power network
  • Recall saved transformer vectors and test with confidence that the setup and evaluations are correct
  • Simulation mode software: Train when a unit is not available, create custom vectors/assets and deploy to instruments
  • Additive/subtractive polarity recognition: Polarity recognition provides confidence in transformer results by performing vector group validation during every test
  • Results on-screen show if the connected distribution transformer is additive or subtractive
  • Pass/fail ratio evaluation for each side of transformer: Open circuit, inductance, short circuit
  • Calculated ratio with percent error (optional pass/fail display)
  • 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
  • Uses the latest technological advancements, providing safe, repeatable, and reliable results
  • Easily manage data with custom transformer entry, auto saving, USB export, and PowerDB import
  • Automatic results storage: Microsoft Excel export, PowerDB Import, or USB printer (sold separately)
  • Rotary knob for function selection: TTR, Go/No Go Impedance, settings, info (BASIC/ADV results export)
