Partial Discharge Analysis in High-Frequency Transformer Based on High-Frequency Current Transducer
Energies, 2018 High-frequency transformers are the core components of power electronic transformers (PET), whose insulation is deeply threatened by high voltage (HV) and high frequency (HF). The partial discharge (PD) test is an effective method to assess an electrical

High frequency transformer computer modeling [PDF]
2007 Australasian Universities Power Engineering Conference, 2007 Frequency response analysis (FRA) technique is nowadays widely used in both factory and field applications as a diagnostic tool for power transformers. The main problem about FRA techniques is to interpret the observed evolution of the frequency response in order to identify failures.
