Transformer Core And Winding Conditions Evaluation From Sfra Measurement Results Using Cross-Correlation Coefficient Function For Tnb Distribution Transformers
Distribution transformers in TNB (Tenaga Nasional Berhad) Malaysia arc exposed to the thermal and electrical stresses. Those stresses are effecting to the main mechanical active parts in transformer such as core and winding. In field, lightning strikes and cable faults may cause problem due to trans...
