MTO106-Transformer Ohmmeter / Transformer winding resistance ohmmeters

Description

MTO106-Transformer Ohmmeter / Transformer winding resistance ohmmeters

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. It has dual channels with a measurement range and accuracy suited to provide accurate 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.Transformer  winding resistance ohmmeter is exceedingly simple to use, which minimises the need to train users. It has a single selector switch for test current and a single button to activate the test cycle.

Transformer  winding resistance ohmmeter MTO106 Applications

MTO106 in India  is mainly intended for field measurements of smaller  transmission and distribution transformers:

• 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
• The instrument can also be used for general resistance measurements including: control wiring, voltage regulators, motors, generators and  all types of connections.
