Electrically Testing Transformers

Groves has the capability of electrically testing transformers from small control transformers to large power transformers.

Depending on the equipment and the customers needs, we can perform the following tests:

  • Transformer Turns Ratio (TTR)
  • Insulation Resistance test (Megger)
  • Overall Insulation Power Factor
  • Bushing Insulation Power Factor
  • Excitation
  • Winding Resistance
  • Sweep Frequency Response Analysis (SFRA)
