ABSTRACT
An accurate 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 short circuit capabilities of power system getting larger and the voltage level going higher the conventional current transducers becomes more bulky and costly.
It appears that newly emerged MOCT technology provides a solution for many of the problems by the conventional current transformers. MOCT measures the rotation angle of th ....etc

The Magnetohydrodynamic power generation technology (MHD ) is the production of electrical power utilising a high temperature conducting plasma moving through an intense magnetic field. The conversion process in MHD was initially described by Michael Faraday in 1893. However the actual utilisation of this concept remained unthinkable. The first known attempt to develop an MHD generator was made at Westing house research laboratory (USA) around 1936.

The efficiencies of all modern thermal power generating system lies between 35-40% as t ....etc

EDDY CURRENT BRAKES

EDDY CURRENT:
It is a swirling current set up in a conductor in response to a changing magnetic field.
By Lenz's law, the current swirls in such a way as to create a magnetic field opposing the change

Eddy Current Brakes
It slow an object by creating eddy currents through emi which create resistance, and in turn either heat or electricity.
Braking action is made by varying the strength of the magnetic field.
¢ A braking force is possible when electric current is passed ....etc

Hi! I am Salman Arshad recently student of Electronics Engineering sixth semester. I have been given a project of Faraday's homo polar generator in one of the subject which i have to submit in a week time. Please help me in that because the project marks will be added in my final paper.

Please if some one have its circuit diagram or any other data so please tell me. I will be thankful.

But note that i want circuit diagram the most.

Thank you. ....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
