Product Overview

RENT MEGGER MTO250 50A Transformer Ohmmeter (Call for Availability)

   The Megger MTO250 50A Transformer Ohmmeter is a line-operated, field-portable instrument designed specifically to measure the resistance of all types of magnetic windings safely and accurately. It can be used to test transformers, shunt reactors, and rotating machine windings, and it performs low resistance measurements on connections, contacts, and control circuits. Megger MTO250 50A Transformer Ohmmeter supports dual set of potential inputs which enables the resistance measurement of either two primary, two secondary windings, or of a primary plus a secondary winding simultaneously. This dual reading, dual injection characteristic, is a highly efficient method of completing tests in a timely manner.

   The Megger MTO250 50A Transformer Ohmmeter can deliver a DC test current up to 50A which reduces test time on high current secondary windings by up to ten times when compared to traditional 10A units. Megger MTO250 Transformer Ohmmeter is well suited to testing the winding plus contact resistance of LTC (Load Tap Changers), as well as assessing the “make-break” transition event, allowing you to diagnose issues such as aggressive pitting, weak springs, and misalignment of contact mechanisms. Data can be stored on the Megger MTO250 Transformer Ohmmeter in nine internal sets (groups) facilitating better organisation while in the field. The Megger MTO250 Transformer Ohmmeter also offers guided test set ups and automated “heat run” testing and reporting via PowerDB Software.
