Using Superposition Principle and Edge Current Model to Compute Impedance of Coil in Logging Tool
نویسندگان
چکیده
Coil antennas are widely used in the welllogging tools. Accurate design needs to know how to model the coil impedance in the presence of formation environment, and with the complex tool structure, e.g., the collar and the shield housing. This paper introduces how to accurately compute the impedance of the coil with very thin wires at high frequency with complex 3D configuration. To predict the resonant frequency, stray capacitance is also obtained in the impedance computation.

An Innovative System for Full-Management of CB Using Current Injection Method
In this article, an innovative supervision system will be proposed that can observe and analyze health of Circuit Breaker’s trip coil. The proposed design also logs changes in the coil's quality and informs network supervisor in case of Circuit Breaker (CB) failure. This system injects small direct currents to the Circuit Breaker connections and the trip coil to compute CB’s health and characte...

In this paper, we proposed a 2-D analytical model for electrical characteristics such as surface potential, electric field and drain current of Silicon-on-Insulator Tunnel Field Effect Transistor (SOI TFETs) with a SiO2/High-k stacked gate-oxide structure. By using superposition principle with suitable boundary conditions, the Poisson’s equation has been solved to model the channel r...
متن کاملInverse Problem in Nondestructive Testing Using Arrayed Eddy Current Sensors
A fast crack profile reconstitution model in nondestructive testing is developed using an arrayed eddy current sensor. The inverse problem is based on an iterative solving of the direct problem using genetic algorithms. In the direct problem, assuming a current excitation, the incident field produced by all the coils of the arrayed sensor is obtained by the translation and superposition of the ...

This paper discusses a time-domain technique for synthesizing acoustic impedance at the diaphragm of a loudspeaker using a proportional-plus-derivative output feedback. The dynamics of electroacoustic transducers such as moving-coil loudspeakers can be readily controlled either by direct feedback principle on acoustic quantities, or by plugging a shunt network at the electrical terminals. Any c...
