Applications
The MTO106 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.
