Now available to rent from TechRentals , Megger MTO330 automated six-winding transformer ohmmeters provide full eight-terminal measurement capabilities to verify factory test readings.
These devices are designed to assist in locating defects in transformers with contact resistance in terminal connections and tap-changers, and are also capable of checking the operation of on-load tap changers.
The ohmmeters feature an 8.4" full colour VGA transflective screen that allows for vision in bright sunlight. The onboard computer has a QWERTY keyboard and push buttons for navigation, designed to make the devices easy to use and highly portable.
Additional features of MTO330 transformer ohmmeters 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; and
- built in auto-demagnetisation.
