| چکیده مقاله: |
| Power transformers has an important role in electrical power transmission and its interruption has financial losses, thus its condition monitoring is essential and performance of this equipment is effective for power system reliability. Vibration Frequency Response Analysis (VFRA) method is one of effective methods to monitor the condition of transformer windings and core. This paper propose a method for internal winding faults detection in power transformer base on vibration signal analysis since these type of fault if not quickly detected, they usually develop into more serious faults which result in irreversible damage to the transformer and the electrical network, unexpected outages and the consequential costs. With occurring an incipient internal fault in transformer current in shorted coils increase and flux leakage distribution changes in faulty transformer, after that axial and radial forces enter to the windings, these forces increase vibration in transformer winding depends on fault severity and location. In this paper Vibration signal is used for internal fault detections. ADXL330 sensor is used for vibration signal measurement in experiment. |
