A High Frequency Transformer Winding Model for FRA Applications
Frequency response analysis (FRA) is a method which is used to detect mechanical faults in transformers. The FRA response of a transformer is determined by its geometry and material properties, and it can be considered as the transformer’s fingerprint. If there are any mechanical changes in the transformer, for example if the windings are moved or distorted, its fingerprint will also be changed...
متن کاملMitigation Transformer Inrush Current Using Modified Transient Current Limiter
This study presents a modified transient current limiter (MTCL) for mitigation the inrush current of transformers. The MTCL is based on conventional transient current limiter (TCL), which, its configuration is modified to overcome the TCL drawbacks of operation. The proposed MTCL offers lower power losses and voltage/current THD during normal operation mode. It needs only one limiting reactor i...
متن کاملPower Auto-transformer Mechanical Faults Diagnosis Using Finite Element based FRA
Frequency response analysis (FRA) is a sensitive method established for testing the mechanical integrity of transformers. However, interpretation of FRA signature still needs expert opinions and there is no FRA interpretation code generally accepted. Various mechanical faults with different extents on power transformers are required to aid FRA interpretation. To address this challenge, in...
متن کاملA Feasible Solution to Distinguish the Transformer Winding Deformation from Insulation Characteristic Impacts on FRA Spectrum
Frequency Response Analysis (FRA) is popular technique which has been used since the last decade as a diagnostic method for transformers. However, accurate interpretation of FRA measurements is still challenging. Recent studies reveal that apart from winding deformation, FRA data can also be influenced by moisture variation in transformer paper insulation. Hence, a specific transformer’s model ...
متن کاملA New Current Transformer Model
This paper presents a current transformer model that is useful on low frequency applications. To describe the iron core magnetic behaviour of the iron core, a hysteresis model is proposed, which is able to generate minor asymmetric loops and remanent flux. The effects of classic eddy current losses and anomalous losses are represented by linear and nonlinear resistors, respectively. The obtaine...
