The Megger MTO106 Transformer Ohmmeter is an easy-to-use, line-operated instrument specifically designed for safe and accurate
field measurement of winding resistance in smaller transmission and distribution transformers.
The MTO106 has dual channels with a wide measurement range and can accurately provide information about the vast majority of power
transformers, reactors and instrument transformers. The test current can be manually set in five different ranges to fit transformers
of various sizes.
The MTO106 is intended for field measurements of smaller transmission and distribution transformers. Applications include:
To verify factory test readings
As part of a regular maintenance program
To help locate the presence of defects in transformers such as increased contact resistance in terminal connections and tap changers
