RENT MEGGER MTO250 50A Transformer Ohmmeter (Call for Availability)
The Megger MTO250 50A Transformer Ohmmeter is a robust, field-portable instrument engineered for precise resistance measurements of all magnetic windings. Perfectly suited for testing transformers, shunt reactors, and the windings of rotating machines, this ohmmeter excels in executing low resistance measurements on vital connections, contacts, and control circuits.
One of the standout features of the Megger MTO250 is its dual set of potential inputs, which allows users to measure resistance across either two primary windings, two secondary windings, or a primary and a secondary winding simultaneously. This dual-reading capability significantly enhances testing efficiency, enabling technicians to complete their tasks swiftly.
Delivering a powerful DC test current of up to 50A, the MTO250 drastically decreases test time on high current secondary windings—claiming up to ten times faster results compared to conventional 10A models. This unit is particularly advantageous for testing the winding and contact resistance of Load Tap Changers (LTC), as well as evaluating "make-break" transitions to identify potential issues like aggressive pitting, weak springs, and mechanical misalignments.
The device boasts the capability to store data in nine internal sets (groups), making it easier to organize your field results. Additionally, the Megger MTO250 Transformer Ohmmeter features guided test setups and automated "heat run" testing, all streamlined through PowerDB Software for comprehensive reporting and analysis.
