Portable and Efficient: An Optimized Way to Measure Winding Resistance on Power Transformers

There are major challenges to gaining fast, efficient, and accurate measurement of winding resistances on large power transformers. Scalability and efficiency for this task have long seemed to be a pipe dream.

Some of the challenges include:

  • Long charging and discharging times
  • Inaccurate temperature measurements for resistance correction
  • Residual magnetism and its unwanted effects
  • Inefficient connection and disconnection of measuring equipment
