Abstract

The paper describes a modeling tool for the design of a new air-cored current transformer called PRiME (planar Rogowski current measurement) designed on a printed-circuit board (PCB) with the coil made of the PCB printed copper layers. The PRiME technology discussed in this paper exhibits a very original way of getting an efficient external field rejection, allowing the design of air-cored transducers with remarkable overall performances. A theoretical model of the PRiME transducer is presented. The model permits to perform systematic optimization of the design parameters, allowing to tune any of them and analyze their impact on the overall PRiME performances. The model is based on the Neumann's formula which allows a straightforward representation of complex coils. The model and the simulation tool are validated versus experimental measurements carried out for different sensor configurations

Simulation

A simulation is the imitation of the operation of a real-world process or system over time. Simulations require the use of models; the model represents the key characteristics or behaviors of the selected system or process, whereas the simulation represents the evolution of the model over time. Often, computers are used to execute the simulation. Simulation is used in many contexts, such as simulation of technology for performance tuning or optimizing, safety engineering, testing, training, education, and video games.

Printed circuit board

A printed circuit board (PCB), also called printed wiring board (PWB), is a medium used to connect or "wire" components to one another in a circuit. It takes the form of a laminated sandwich structure of conductive and insulating layers: each of the conductive layers is designed with an artwork pattern of traces, planes and other features (similar to wires on a flat surface) etched from one or more sheet layers of copper laminated onto and/or between sheet layers of a non-conductive substrate.

Computer simulation

Computer simulation is the process of mathematical modelling, performed on a computer, which is designed to predict the behaviour of, or the outcome of, a real-world or physical system. The reliability of some mathematical models can be determined by comparing their results to the real-world outcomes they aim to predict. Computer simulations have become a useful tool for the mathematical modeling of many natural systems in physics (computational physics), astrophysics, climatology, chemistry, biology and manufacturing, as well as human systems in economics, psychology, social science, health care and engineering.
