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.

regards
ASAD ALI
thanks for start helping me but i m f ....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 carefully to avoid electr ....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. Conventional in ....etc

Changes in the volume of pulmonary air change the conductivity distribution in the thorax. On the basis of this effect, we describe an instrument without contact to measure the volume of the lung which is suitable for applications such as monitoring of respiration in patients of sleep for the sleep apnea. The instrument is based on a magnetic coil and is positioned in a soft mattress below the subject. Current AM frequency is applied to the coil to generate eddy currents in the tissue near the drivers, which in turn generat ....etc
