The Megger MTO250 50A Transformer Ohmmeter is a portable, line-operated device built for precise resistance testing of transformer, shunt reactor, and rotating machine windings. It supports dual potential inputs, allowing simultaneous measurement of primary and secondary windings. With a DC test current up to 50A, it minimizes test times significantly compared to standard 10A instruments. Additional features include guided setups, automated heat run testing, and integrated data storage for nine test groups.
Engineered for efficient diagnostics, the Megger MTO250 is ideal for assessing winding and contact resistance in LTCs, detecting transition events such as contact wear, weak springs, and misalignment. Dual injection readings ensure timely and reliable testing in demanding field conditions.
Testwall can supply the used Megger MTO250, fully tested. With expert support and global delivery, Testwall ensures high-performance instrumentation with unmatched reliability and service quality. Please contact us directly if you need calibration or repair of the Megger MTO250.
