Simulation and Analysis of Electromagnetic Interference Effects with 900 MHz Frequency on Various EMI Protection Model

Abstract: Electromagnetic interference possesses potential hazard towards equipment in an oil and gas refinery plant. Installing mesh common bonding network with high conductor density underneath the equipment is known to be an effective protection method against this thread. Nevertheless, using more conductor would require higher cost. Henceforth, a series of simulations has been executed to determine the optimum mesh configuration. The modelling and simulations were carried by using COMSOL software. In the simulations, the mesh diagonal (D) were varied from 6.9mm to 70.5mm. The results show that the electromagnetic interference was less for mesh with smaller D. However, the total cost rose exponentially when D was decreased to a certain value. All but all, this study found that mesh configuration with D 14mm is the most optimum option.
