SUPERCONDUCTORS FOR POWER TRANSMISSION AND DISTRIBUTION

How can superconductors be applied in the electric distribution industry?
We have defined that superconductors are materials that have no resistance to the flow of electricity and are one of the last great frontiers of scientific discovery.  Having no resistance means having no power loss. So how can we use this technology for industry’s benefits?
Electric Utility and Power Applications of SuperconductivityAs an electrical engineer, it is very easy to understand the advantages of having no resistance in the conductors can offer. To name one, having no conductor resistance would mean no power losses can be produced thus having a very efficient system.
High-Temperature Superconductivity (HTS)HTS has the potential for achieving a more fundamental change to electric power technologies than has occurred since the use of electricity became widespread nearly a century ago. In many ways, the transmission and distribution of electricity are poised for advancement the way that the Internet was poised for its take-off in the 1990s.
Just as fiber optics enabled the “information superhighway” by supplanting lower-capacity copper, superconductivity is enabling an “energy superhighway” by supplanting copper electrical conductors with a ceramic superconducting alternative that has higher capacity while eliminating resistive losses.
Benefits of HTS Power Applications
• Increased grid reliability and security by providing efficient power interconnections with high capacity.
• Minimal environmental impact: HTS cables can be readily permitted and installed in dense urban areas.
• Low-impedance design enables dynamic control of alternating current power flow, alleviating grid congestion.
• Reduced right-of-way requirements (smaller footprint).
• Superconducting fault current limiters do not add impedance to the circuit during normal operation.
Superconductor Electric Distribution System Application Example          
• South Korea To Build World's Longest Superconductor Electric Distribution System.
                      o It will only be a half mile long, but Korea Electric Power Corp has taken the first step in building what will be the world's current longest . To do so they have placed the world's largest order for high temperature superconducting wire from Massachusetts-based American Semiconductor:Some 80,000 meters (50 miles) of the wire will be made into 22.9 kV cable by LS Cable and installed near Seoul in 2010. The completed system will be able to carry 50 MW of power.

PARTS OF A POWER TRANSFORMER

What are the name of the basic parts of a Power Transformer? We can not deny the fact that only a handful of electrical engineering students are presently familiar with power transformers especially on what it looks like. Unlike a transformer we found in our homes, a power transformer’s appearance and construction is somewhat more complicated. It is not just a simple winding with a primary and secondary terminal although basically any transformer has one. The function that a power transformer plays in an electrical system is very important that an electric utility can not afford to loss it during its operation. Our discussion here will focus more on the basic parts and functions of a power transformer that are usually tangible whenever you go to a substation . Although not all power transformers are identical, nonetheless they all have the following listed parts in which the way of construction may differ.

ELECTRIC MOTOR NAMEPLATE SPECIFICATIONS

How do we interpret an electric motor nameplate? Motor standards are established on a country by country basis.Fortunately though, the standards can be grouped into two major categories: NEMA and IEC (and its derivatives). In North America, the National Electric Manufacturers Association (NEMA) sets motor standards, including what should go on the nameplate (NEMA Standard MG 1-10.40 "Nameplate Marking for Medium Single-Phase and Polyphase Induction Motors").

DISADVANTAGES OF Y-Y CONNECTION IN THREE PHASE SYSTEM

What are the disadvantages in using y-y connection? The Y-Y transformer connection was poorly understood in the early days of power engineering and it received a very bad reputation when it was first used; in fact, this connection was avoided for a long time until its limitations were overcome by good engineering practice. Some of the inherent disadvantages of the Y-Y connection are discussed below:
