Megger TTRU3 True 3 Phase Transformer Turns Ratiometer

The Megger TTRU3 is an advanced transformer turns ratiometer with a 3Ø voltage output and step up turns ratio testing. Able to easily evaluate phase shifting and zig-zag transformers and perform ten second 3Ø tests, the TTRU3 improves speed and accuracy when determining a transformer's mechanical condition. This unit's streamlined design includes a 7in. touchscreen with color display, a pc operated remote control, and the ability to transfer results to a USB memory card. Combining portability with comprehensive measurement capabilities, the Megger TTRU3 is a valuable tool for TTR testing needs.
