Especially for electrical machines, both the supplier and the user are interested in the results of PD measurements. However, PDs hardly represent the cause of the failure, more likely they are claimed as the outcome of a failure. This paper deals with the insulation of a 6 kV electrical machine, whereas PD measurements were carried out at a single stator from wound coils. During manufacturing, these coils were equipped with different materials for the OCP （outer corona protection）. Using different PD measurement systems and different bandwidths, investigations of the PD behavior of the coils were carried out. Additionally, the surface resistivity of the corona protection was determined. As a result, conclusions for the correlations between the resistance of the OCP as well as the PD behavior are stated. Furthermore, the influence of using different measurement systems, different measuring circuits, and different bandwidths is shown.展开更多

Methods： This study involved 10 patients who suf- fered from high-voltage electrical bum injury of the scalp. Scalp reconstruction was done by different modalities ac- cording to the size and location of the defect. Results： Complete flap viability was achieved in all the cases. We had one case of gapped wound which was managed only by dressing. Widening of the scar was found in 2 cases. Conclusion： Rotation, advancement and transposi- tion scalp flaps are used for reconstructing scalp defects caused by electrical bum. The choice of ideal flaps for re- construction depends upon the size and site of scalp defect.展开更多
