Description

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
