hello,i m ASAD ali from i m electrical engineering final year student and i m intrusted in transformer so i want to go for some good project about trasnformer
so please send me information about measurement of inrush current in transformer and how can i use it for the protection of distribution transformer by designing some relay or some thing else please give me good idea and tell me how i should start my project i hope i ll get good and very usefull guide line from you sir.

A Linux Device Driver for USB to USB Direct Link Device

The first version of the Universal Serial Bus (USB) specification was released in January 1996. In April 2000, version 2.0 of the USB specification, which supports transfer rates up to 480 Mbps, was released. Because of its low cost, high data-transfer rate, ease of use, and flexibility, USB has gained wide acceptance in the computer industry. Today, many peripherals and devices connect to computers through USB interfaces. Currently, most general-purpose operating systems pro ....etc

1. Abstract
The second harmonic inrush restraint function of transformerdifferential relays maintains security of the differential protectionduring transformer inrush events. The typical setpoint for thesecond harmonic restraint is the relay manufacturer’s defaultor recommended setting of 20% of fundamental current, withsome adjustment based on operating experience. However,some operating situations may result in levels of secondharmonic current lower than 20% during inrush, and levels maybe as low as 5%. This lower level of second h ....etc

USB EXPLAINED: AN INTRODUCTION TO USB AND ITS FUTURE


USB HISTORY
The Universal Serial Bus (USB) was introduced to the world of PC computing to solve the growing problem of how
to connect peripherals to a PC. The world of desktop computers needed a way, not only to physically connect
devices, but also allow them to be identified and categorized to enable a simple ease of use and method of discovery.
Prior to USB, many people overloaded the use of their serial and ....etc

Wireless USB

Abbreviated as WUSB this short-range, high-bandwidth wireless radio communication combines the speed and ease-of-use of USB 2.0 with the expediency of wireless technology and is based on the WiMedia Alliance's Ultra-WideBand (UWB) common radio platform, which is capable of sending 480 Mbit/s at distances up to 3 meters and 110 Mbit/s at up to 10 meters. However USB Implementers Forum discourages the practice of calling it WUSB and prefers to call the technology Certified Wireless US ....etc

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
