TTRU3

True 3 Phase Transformer Turns Ratiometer

  • Guaranteed accuracy ±0.05% from -20°C to +50°C
  • 3Ø test voltage - up to 250V
  • 3Ø step up ratio (patent pending)
  • Phase shifting & zig-zag transformers tested easily and accurately
  • Smallest/lightest 3Ø test set on the market
  • Fast 3Ø tests - less than 10 second

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 (patent pending). 3Ø voltage output offers numerous advantages to testing with today’s busy schedules. 

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 in. (180 mm) color touch display, as well as an optional printer so results are never lost. This is complimented with remote control which can be operated from a PC, as well as the ability to download results to a USB memory device.

TTRU3 PC Software

 

CRITICAL BUG FIX: v2.2.1 resolves a bug introduced in v2.2.0 which may result in decreased CPU performance of the TTRU3.  If you previously installed v2.2.0, it is highly recommended that you upgrade to v2.2.1.  No other functionality changes were made between these versions.
