The evaluation of electromagnetic transients in overhead power lines due to nearby lightning return strokes requires accurate models for the calculation of both the incident lightning electromagnetic pulse (LEMP) and the effects of coupling of this field to the overhead lines. Meanwhile, the influence of ground resistivity and the number of line conductors should be considered on analyzing the distribution...
In this paper, a novel design, control and implementation of a three degree-of-freedom (DOF) compact positioner is presented with high resolution in tens of nanometer-scale precision positioning and millimeter-level long travel range. According to the serial flexure mechanism design, whose motion comes from the elastic deformation of the flexure and the force allocation of five pairs of electromagnetic...
