Design Modification of Rogowski Coil for Current Measurement in Low Frequency
The principle object of this paper is to offer a modified design of Rogowski coil based on its frequency response. The improvement of the integrator circuit for nullifying the phase difference between the waveforms of the measured-current and the corresponding terminal voltage is a further object of this investigation. This paper addresses an accurate, yet more efficient measuring and protect...
متن کاملA simple miniature magnetic probe with inherent electrostatic rejection
Inductive magnetic probes are often used to measure oscillating magnetic fields in plasma.r3 The sensitivity of a magnetic probe to electrostatic potentials (“capacitive pickup”) is usually an important consideration. Centertapped construction of such a probe, shown in Fig. 1 (b), helps to minimize capacitive pickup with respect to a simply wound probe [Fig. 1 (a)]. This relies on the fact that...
متن کاملOne-Dimensional Haptic Rendering Using Audio Speaker with Displacement Determined by Inductance
We report overall design considerations and preliminary results for a new haptic rendering device based on an audio loudspeaker. Our application models tissue properties during microsurgery. For example, the device could respond to the tip of a tool by simulating a particular tissue, displaying a desired compressibility and viscosity, giving way as the tissue is disrupted, or exhibiting indepen...
متن کامل3-D RF Coil Design Considerations for MRI
High-frequency coils are widely used in medical applications, such as Magnetic Resonance Imaging (MRI) systems. A typical medical MRI includes a local radio frequency transmit/receive coil. This coil is designed for maximum energy transfer or wave transfer through magnetic resonance. Mutual inductance is a dynamic parameter that determines the energy quantity to be transferred wirelessly by ele...
متن کاملImproved Mutual Inductance of Rogowski Coil Using Hexagonal Core
Rogowski coils are increasingly used for measurement of AC and transient electric currents. Mostly used Rogowski coils now are with circular or rectangular cores. In order to increase the sensitivity of the measurement of Rogowski coil and perform smooth wire winding, this paper studies the effect of increasing the mutual inductance in order to increase the coil sensitivity by presenting the ca...
