Advanced Diagnostic Testing for Power Transformers


Webinar: Advanced Diagnostic Testing for Power Transformers

Advancements in transformer testing technologies can now provide technicians with additional diagnostic capabilities but are not always utilized or understood by the industry. Traditional power factor and leakage reactance testing has historically been performed at or around the line frequency of 50/60 Hz. Newer technologies in test equipment design make it possible to greatly extend the frequency range of test signals, providing technicians with additional information relative to the health of the transformer components. This presentation will define the advantages of variable frequency power factor, (VFPF), and frequency response of stray losses, (FRSL) with an extended frequency range for leakage reactance. Our final advanced testing method will focus on dynamic DC winding resistance, as a method of gaging the health of the OLTC.
