The converter quadrivalve is one of the key devices in a ±400kV converter station valve hall at an altitude of 3820m in western China. The complex structure of quadrivalve may lead to serious electric field distortion when without well-designed shields. Besides, in view of high altitude, corona discharge is easier to occur, which threatens the secure operation of HVDC system. In this paper, the structure...
Resonance Ultrasonic Vibration (RUV) metrology offers a sensitive non-destructive real-time solution to silicon wafer crack detection. The stresses generated in the wafers by the handling device used in the RUV method may have a significant influence on the effectiveness of this method, particularly for thinner wafers. The handling stresses produced by different designs of the vacuum wafer holders...
