Product Information

Description

The MTO250 Transformer Ohmmeter is used to:

  • Perform field testing of CT, PT, power transformer windings and their associated tap changers, and motors/generators.
  • Verify factory winding resistance test results.
  • Perform factory heat run tests.
  • Diagnose and pinpoint problems such as the presence of defects in transformers, such as loose connections, and poor tap changer operation.
  • To validate proper “make-before-break” operation of load tap-changers (LTC).
