Power Quality in Electrical Power System Assignment

Power Quality in Electrical Power System - Assignment Example Hence the load that develops is one of the most prominent reasons as well as the most important victim of power quality related issues. Since they are non-linear in nature this causes great load which results in turbulence in the waveform of the voltage.   Ã¢â‚¬Å"Component  can be established. It is possible in the same way to correlate certain disturbances with consumption patterns of electricity, such as the early evening television peak in the harmonic distortion and signal Processing of  Power Quality etc.† (Bollen, 2006) Thus in order to overcome this disturbance there are numerous components used. These components prove to be quite efficient as they manage the load. Basically these devices are capacitors which are responsible to store electrical charges within them. This is designed according to the task that they need to cater. These capacitors aid in effective functioning of the machine ensuring standard power quality. The ranges may vary depending on the purpose they are meant to serve, today it has been observed that they also posses self healing capabilities which increase the life of the capacitor and moreover the product. This not only helps to increase voltage quality but also is economical. †¢ Why is it important to maintain high power quality? It is extremely important to maintain high power quality. It is noted that the best power quality is when the frequency of the electric supply results in a steady magnitude which coincides with the frequency of the sinusoidal waveform of the voltage. Since there is always some error and non-zero impedance occur in the supply system which is because of the great amount of load that might be faced by the system. This gives birth to another phenomenon of transients and outrages which fluctuates the reality. Hence when one considers the power quality they consider to what extent the power supply system is in correspondence with the ideal power supply system. â€Å"The targeted  power qualit y disturbances on the utility side include input voltage harmonics, voltage unbalance, and input inductor unbalance.† (Lee, 2008) these are the major causes of power disturbance which make it essential to maintain high power quality. Hence if the power quality of a system is good, reliable and efficient then any load which is associated with it will work effectively and efficiently. Also it will help to cut down the installation cost and minimize the carbon footprints. On the contrary if the power quality of a system is not satisfactory then the life of the product will fade furthermore the effectiveness of the installation will be badly affected. Economy would hamper as well as the cost of installation would eventually maximize and the carbon footprint will also be affected. This can result in no operation what so ever. The following reasons justify so as to why maintaining power quality is essential They will help to avoid unexpected power failures. Failure or malfunction of product is less. Causes no or little damage to sensitive devices. Avoids interference in communication. Saves loses and protects the systems. There is no requirement of increasing the installation in order to deal with failures resulting in economical solutions.

Logitech International SA - Case Study Example The ability to innovate is a key success factor which determines the performance of a business organization (Logitech Annual Report 2007). Bringing the products in the market at the right time enables a company to outperform its competitors and survive in a very risky market. Logitech is operating in a global landscape exposing it to the fluctuations of exchange rates (Logitech Annual Report 2007). This exchange rate risk makes the company vulnerable to the changes in value of currencies. For instance, the weakening of the dollar due to the economic recession makes its income in the United States lower when expressed in Swiss franc. This in turn can make investors wary in investing in Logitech noting that exchange rate fluctuations can shrink the company's revenues and profits when expressed in Swiss francs. Economically speaking, the company is also exposed to the recession in the United States and the food crisis happening in Asia. It should be noted that these are Logitech's major markets. As the disposable income of consumers in these regions is squeezed, IT products become unappealing as they turn to allocating budgets for basic necessities like food and medicine. The whole IT industry is poised to benefit from the economic development of countries like China and India.
