Faster transformer testing with fewer connections.
The Megger MTOU3 is a three-phase winding resistance ohmmeter designed to improve safety, simplify setup and deliver accurate results with greater confidence.
With a single, one-time lead connection, technicians can perform:
- Vector confirmation
- Winding resistance testing
- Automatic demagnetisation
Dual winding excitation helps speed up primary and secondary measurements, while automatic vector confirmation checks the correct transformer vector before every test.
Less reconnecting. Fewer ladder climbs. More confidence in the result.
