Abstract
This paper presents an analytic current model for capacitively coupled Single-Electron Tunneling Transistors (SETTs) that is based on a modified M-state steady-state master equation. Based on this current model we also derive a current noise model for SETT. To validate the proposed models we calculate their characteristics at different device parameters and different operation temperatures and compare them with the corresponding characteristics calculated by the full master equation method. The results indicate that the propo ....etc

ABSTRACT

Optical current sensors are achieving increased acceptance and use in high voltage substations due to their superior accuracy, bandwidth, dynamic range and inherent isolation. Once deemed specialized devices intended for novel applications, optical sensors have risen to a performance level exceeding conventional magnetic devices. A specific area where optical current sensors outperform conventional iron core transformers is the measurement of very high currents that occur during a fault on the power system. Conventiona ....etc

Current generation moves into wireless technology
Current generation moves into wireless technology. Every one wishes to use remote controls. In this way, the speed of the DC motor is controlled by IR rays. IR rays get modulated with combination of data signal and carrier wave of 38 kHz. At the received end, the modulated signal is demodulated which is given to another controller, connected to the Dc motor driving circuit.

ABSTRACT

Downscaling or miniaturization has been a recent major trend in modern science and technology. Engineers now fabricate microscale devices such as microchannel heat exchangers, and micropumps that are the size of dust specks. Further major advances would be obtained if the coolant flowing in the microchannels were to contain nanoscale particles to enhance heat transfer. Nanofh.dd technology will thus be an emerging and exciting technology of the 21st century.
This paper gives a brie ....etc

Magneto-optical current transformer technology (MOCT)

An accurate electric current transducer is a key component of any power system instrumentation. To measure currents power stations and substations conventionally employ inductive type current transformers with core and windings. For high voltage applications, porcelain insulators and oil-impregnated materials have to be used to produce insulation between the primary bus and the secondary windings. The insulation structure has to be designed car ....etc

An accurate electric current transducer is a key component of any power system instrumentation. To measure currents power stations and substations conventionally employ inductive type current transformers with core and windings. For high voltage applications, porcelain insulators and oil-impregnated materials have to be used to produce insulation between the primary bus and the secondary windings. The insulation structure has to be designed carefully to avoid electric field stresses, which could eventually cause insulation breakdo ....etc
