This is a new technique for the protection of transmission systems by using the global positioning system (GPS) and fault generated transients. In this scheme the relay contains a fault transient detection system together with a communication unit, which is connected to the power line through the high voltage coupling capacitors of the CVT.

Relays are installed at each bus bar in a transmission network. These detect the fault generated high frequency voltage transient signals and record the time instant corresponding to when the initial ....etc

Lightning is one of the more spectacular and awesome weather phenomena. Lightning comes in various types and forms. Usually the intricacy of lightning is not visible to the human eye, because it happens so quick; but time-exposure photos catch and reveal the beauty of lightning very well. Lightning is dangerous, but without lightning, there might not be life on this planet. The National Board of Fire USA reports that lightning is the number one cause of farm fires. Lightning is also responsible for more than 80% of all livestock losses due to a ....etc

Lightning Protection Using LFA-M

Introduction
A new simple, effective and inexpensive method for lightning protection of medium voltage overhead distribution line is using long flashover arresters (LFA). A new long flashover arrester model has been developed.

It is designated as LFA-M. It offers great number of technical and economical advantages. The important feature of this modular long flashover arrester (LFA-M) is that it can be applied for lightning protection of overhead distribution line against both induced overvoltages and dire ....etc

Surge current protection using superconductors

Introduction
The recent growth of power circuit capacities has caused fault currents to increase. Since the protection of power systems from the fault currents is very important, it is needed to develop a fault current limiter.

A fault current limiter is required to assure (1) rapid reaction to fault currents, (2) how impedance in normal operation and (3) large impedance during fault conditions. A super conducting fault current limiter (SCFCL) can meet these requirements superconductors, bec ....etc
