• 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.
