Intermittent turn-to-turn winding faults diagnosis in power transformers by the on-load exciting current Park's Vector Approach
| Resumo: | This paper presents the application of the on-load exciting current Park's vector approach for diagnosing permanent and intermittent turn-to-turn winding faults in operating power transformers. A digital model for the simulation of the behavior of three-phase transformers affected by the presence of winding faults is also proposed. Experimental and simulated results demonstrate the effectiveness of the proposed diagnostic technique, which is based on the on-line monitoring of the on-load exciting current Park's Vector patterns. |
