If anyone has used VLF AC for withstand testing coils (instead of 60 Hz AC or DC), and/or used VLF for the voltage source to perform Tan Delta/Power Factor or Partial Discharge testing, would you be willing to share your experiences with the rest of us? This will help our industry to maybe move toward using this method of testing larger size windings.
