Megger MTOU3 three-phase winding resistance ohmmeter

The MTOU3 uses a safe, one-time connection for complete winding resistance assessment of power, distribution, and instrument transformers with automatic adaptive demagnetisation, eliminating the risk of tripping system protection when the transformer is put back into service.

Perform vector confirmation, winding resistance, and demagnetisation tests with the same one-time lead connection. Guided by color-coded leads and extendable clamps with on-screen vectors that match the transformer nameplate, the easy-to-follow setup ensures the right result the first time – just click start!

Auto vector confirmation before every test ensures that the proper transformer vector is selected.
