Megger MTO330 automated six-winding transformer ohmmeter

The Megger MTO330 automated six-winding transformer ohmmeter, available for rent, provides full eight-terminal measurement capability to verify factory test readings.

It helps locate defects in transformers with contact resistance in terminal connections and tap changers and will also check the operation of on-load tap changers.

The 8.4″ full-colour VGA transflective screen allows vision in bright sunlight and the onboard computer has a QWERTY keyboard and push buttons for navigation, providing ease of use and portability.

Features include: one-time connection principle; interchangeable lead set with the Megger 3-phase series of TTRs; simultaneous winding magnetisation for fast and accurate DC winding resistance measurement of high inductive loads; built-in auto-demagnetisation.
