For humans, we know that water and electricity . are . not good to mix. For some animals, this safety concern about electricity is not a problem. In fact, they survive because they can use electricity in the . Made by. Abhishek. Walter Paul. 11104EN072. INTRODUCTION. Modern . power system are growing fast with . more generators. , transformers and large network in the system. whenever a fault occurs there is a need for the protection of these system. Here we discussed the use of superconductor as protective device for surge current protection. Superconductors conduct electricity, offering zero resistance below certain temperature. We study different types of superconductor as fault current limiter and their working. A) 1 m/s.. B) 1 km/s.. C) 10 m/s.. D) the speed of light.. E) 1 mm/s.. 2) When a current flows through a metal wire, the moving charges are. A) positive metal ions.. B) negative metal ions.. C) only electrons.. Chapters 18 - 19 . Chapter 18 Topics:.

Sketch a graph to show how the rotation of the ring will affect the reading on the attached voltmeter.. Eddy current inspection is one of several NDT methods that use the principal of “electromagnetism” as the basis for conducting examinations. .. Eddy currents are created through a process called electromagnetic induction. When alternating current is applied to the conductor, such as copper wire, a magnetic field develops in and around the conductor. This magnetic field expands as the alternating current rises to maximum and collapses as the current is reduced to zero. If another electrical conductor is brought into the close proximity to this changing magnetic field, current will be induced in this second conductor. Eddy currents are induced electrical currents that flow in a circular path. They get their name from “eddies” that are formed when a liquid or gas flows in a circular path around obstacles when conditions are right.. Electric Current.
