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

Lightning and Surge Protection Of Modern Electronic Systems

Introduction
In virtually all aspects of our modern lives, microprocessors and integrated circuits (ICs) are hard
at work processing digital data, controlling critical systems and communicating information
through ever-expanding global networks. These now common components have dramatically
lowered system costs while increasing the power and flexibility of modern electronic systems in a
manner unimaginable just a few years ago. Yet, few developers se ....etc

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, because of their sharp transition from zero resistance at normal cu ....etc

Voltage surges are unpredictable, momentary increases in voltage. Typically, lightning, inductive switching, or power switching cause surges, which can damage the insulation in building wiring, electrical appliances, or electronic equipment.

Power surges, which can create havoc with today's highly sensitive electrical and electronic equipment, are an unavoidable fact of life. Power surges, both voltage and current, are occurring continually in today?s power systems.

Whether they occur naturally, such as from lightning and static electri ....etc
