measurements of three-phase voltage and current samples obtained from the PSCAD/EMTDC. Fig. 8 depicts the 220 kV, 50 Hz simulated system one-line diagram. The other related parameters of the simulated system are shown in Table 1, transmission lines are assumed completely transposed. Fig. 9 & 10 show 3ph voltages and currents waveforms for 3ph to ground fault at 50% of the second line without and with UPFC respectively. It is clear that when UPFC is involved in the fault loop, the the voltage and current signals would be deviated from the actual value.

Earthquake early warning systems alert devices and people when shaking waves generated by an earthquake are expected to arrive at their location. The seconds to minutes of advance warning allow people and systems to take actions to protect life and property from disastrous shaking. Devices such as isolation systems and dampers are designed to reduce vibrations of structures being effected in an earthquake and are added to the design of some modern buildings mainly in Japan. Advanced radar and infrared cameras take a series of images collecting data to identify signs of earthquakes. Advanced Interferometric Synthetic Aperture Radar shows fault movements over a period of years. Modems and Data Processing centres receive data collected by satellites to analyse the trends recognised in the electromagnetic emissions, radar pictures, infrared readings and elf

The analysis of DTL and the energy sector will provide an overview of the sector and the decision categories that team members are responsible for safeguarding DTL Power. Also, this section describes the dependence the energy sector has on cyberspace; as well as the threats and vulnerabilities that it may suffer. Additionally, defensive and

Theoretical analysis is one of the most significant phases of the project. The high resistance measurement system developed during this project is primarily based

Hundreds of deaths occur each year due to electrocutions in or around the home. Over two thirds of these deaths and thousands of electrical shocks can be prevented if a ground fault circuit interpreter is installed properly in the homes branch circuits. However many people do not know what a ground fault circuit interpreter or "GFCI" is or if it is installed in their homes.

The narrator's desire for light is caused by the fact that the light illuminates "the blackness of [his] invisibility." He lives in a secluded basement and "tapped into a power line" in order to receive electricity. The narrator realized that the light makes him less invisible to himself. He was chased into the darkness because of people's inability to see him, deeming him invisible. However, the light always him to see himself and be aware of his on existence. The light shows him what other people fail to see; it brings him out of the darkness that he is trapped in.

The human race has advanced a great deal over the course of recent history, particularly so since the 18th century. Countless of these developments in society can be attributed to the achievements of engineers - however, despite this, many do not realise their contribution and importance. One of the fundamental bases behind these engineering feats is the harnessing of energy sources, such as electrical and heat energy. This has allowed for many innovations, for example power stations, transportation, communications and computers, which have all become critical to society and the modern world in which we live.

Throughout this research paper, the reader will have a better understanding of the different forms of resistance. Also the reader will have the ability to compare the two types of resistance which were active and passive. And finally the reader will be abl

Over the years monitoring techniques have been implemented in many different fields for a variety of different applications. We have remote controlled televisions, audio systems and other consumer electronic appliances. Then there are remote controls in the new generation cars for door locking. But all these devices have the limitations that their area of operation is confined to a certain range. If the remote control is out of this range then it ceases to operate in its expected manner. This is because the

A notable example of an inevitable accident occurring in a complex system is the Fukasma dhi nuclear accident. On the 11th March 2011 a 9.0 magnitude earthquake, named the Great East Japan Earthquake occurred off the coast of Japan. The earthquake caused two tsunamis, which “disabled the power supply and cooling of three Fukushima Daiichi reactors”. Within three days, the three main cores melted due to the disabling. Large amounts of radioactive material was released into the atmosphere. According to Perrow, the nuclear accident is classified as a normal accident, because the earthquake was the catalyst of the unforeseen cascading failure within the nuclear power plant’s complex system.

The aim of this project is to construct a single phasing monitor and prevention system using 8bit microcontroller. Anti-single phasing relays or single phasing preventer are required for critical
