This project design and constructions high voltage high frequency transformer or tesla transformer. The tesla transformer is design at 500 kV rating voltage and 250 kHz resonant frequency. By coupling air axle and have the air are the electric insulator between primary coil and secondary coil Which primary coil test at 60 degree Group part spark gap is will the Electrostatic gap. This paper propose and consider high voltage high frequency transformer at 500 kV and 250 kHz rated. For use a transformer aforementioned is the equipment for test flash over prenouaena of porcelain insulator and electric insulation.

This object of research is to compare the computation solution of two numerical methods. The methods were Jacobi iteration method and Guass-Seidel iteration method for the stickslip problem at die of the extrusion process. The Navier-Stokes equation was analysed by finite element method of semi implicit Taylor-Galerkin/pressure-correction scheme to approximate velocity and pressure for Newtonian fluid in two dimentional cylindrical coordinate system. Solution accuracy was improved by the gradient recovery technique. The convergence analysis revealed that Guass-Seidel method approach to exact solution was better than Jacobi iteration method that is because Guass-Seidel iteration method had less solution than Jacobi iteration method.
