DESCRIPTION
The NEW Megger TTRU3 transformer turns ratiometer uses a
revolutionary design to perform a complete series of measurements on
a transformer, including 3Ø step up turns ratio testing (patented).
3Ø voltage output offers numerous advantages to testing with today’s
busy schedules. Features include:
Validation and recognition of phase relationship of vector
groups facilitated with on screen vector rotation and Auto
vector recognition
Accurate measurement of phase shift relationship (for phase
shifting transformers and Zig Zag vector configurations).
Faster testing – all 3 phases tested simultaneously
More reliable - removes the requirement for internal relay
switching which is a common cause of failure
The TTRU3 is an important tool for determining the mechanical
condition of transformers. All ratio tests are performed in one
instrument, with only one 3Ø lead-set connection. The TTRU3 utilizes
the latest 7 inch (180 mm) color touch display, as well as an optional
printer so you never lose your results. This is complimented with
remote control which can be operated from your PC, as well as the
ability to download results to a USB memory device.

TYPICAL PROBLEMS FOUND USING THE TTRU3
  • Loose connections
  • Turn-to-turn shorts
  • Broken Strands
  • Winding deformation
  • Tap changer contact problems
  • Core problems

TESTING PERFORMED
  • All with one instrument and 3Ø lead-set connection!
  • Ratio - 3Ø Step Up testing for power transformers
  • PhaBse shift & phase deviation
  • Polarity
  • Magnetic balance/flux distribution
  • Excitation current characteristics
  • Auto vector detection/recognition

FEATURES AND BENEFITS
  • 3Ø test voltage - fast testing of all transformers
  • Patented 3Ø Step Up Testing
  • Confirm expected nameplate vector configuration
  • Ability to measure actual vs expected phase shift
  • Unique kelvin clamps with adjustable 3-inch jaw
  • Banana plug input for connection to terminal blocks
  • Turns ratio % error vs nameplate with pass/fail
  • PC interface via USB for remote control operation and
  • downloading of test results
