Abstract The subject of electrical hazards analysis has been recognized by a small segment of the electrical industry for many years. The petrochemical industry and many government institutions have performed research on this subject for over twenty years. For the most part however, the electrical industry, at least at the user level, has largely ignored the subject, essentially reacting to catastrophic accidents, rather than proactively trying to predict and prevent them. Recent changes in consensus standards, along with a better general understanding of the seriousness of electrical hazards have resulted in a renewal of interest in the subject. As the awareness of electrical hazards increase many are puzzled by phrases like; “Limited”, “Restricted”, and “Prohibited Approach...

...ELECTRICAL SAFETY Safety in the workplace is job number one for employer and employee. It is especially important for those who install and service electrical system. Electrical safety defines as “Recognizing hazards associated with the use of electrical energy and taking precautions so that hazards do not produce injury or death”. Nothing can replace a worker or loved one that has died or suffered their reparable consequences of an electrical accident. Government statistics shows that electricity cause more than 20,000 fire a year, almost half of all accidental UK house fire. Each year, about 70 people are killed and 350,000 are seriously injured due to an electrical accident in the UK. Modern living has meant we use more and more electrical appliances in the home. For instance, just 20 years ago the average uk home had a hi-fi system and one TV whereas today it is more likely that there are at least two TVs, games console, microwave and computer.so that risk of electricity accidents in the homes are more higher than before. It has seen in the UK that there are lots of people drying their cloths on electrical heater. This is particularly dangerous and could cause electric shock or fire. Heater have ventilation slots to prevent overheating. If this slots are covered up, the appliance could over heat and catch fire. Many time people are drilling the wall to fix nail without knowing what...

...Electrical Components of Shop Unit Electrical for HVACs Southern Technical College Abstract A working overview of our Goodman Package Units located in the lab. The overview will show comprehensive knowledge of the electrical and electronic components associated with our lab equipment. Electrical for HVACs The electrical systems of an air conditioning unit are easier to understand if a technician breaks the complex schematic into individual circuits. This will provide an efficient method for diagnosing and repairing systems. The narrative covers the major loads in the system which is the compressor, compressor fan, and evaporator fan. On heat pump units, when the room thermostat set to the cooling mode, 24Vac is supplied to terminal “O” of the defrost board and to the reversing valve. As long as the thermostat is set for cooling, the reversing valve will be in the energized position for cooling. The constant 24Vac at the “O” terminal of the defrost board signals the board that the unit is in cooling. On a demand for cooling, the room thermostat energizes “Y” and “G”. This supplies 24Vac to terminal “Y” of the defrost board, the compressor contactor and the “G” terminal in the unit. The compressor starts in the cooling mode and the indoor blower motor starts. The contactor closes and turns on the compressor and condenser fan. When the cooling demand is satisfied, the room thermostat removes the 24Vac from “Y” and “G”. The contactor opens and turns off the compressor...

...Electrical Hazards and Safety in Electrical Installations K K Sharma Lingaya’s University, Faridabad, Email: krishan_ksharma@yahoo.com Abstract: “Electrical Safety is not an option — it is absolutely necessary for workers and employers alike”. Safety in the workplace is job number one for employer and employee alike. It is especially important for those who install and service electrical systems. Nothing can replace a worker or loved one that has died or suffered the irreparable consequences of an electrical accident. No matter how much an employer tries to safeguard its workers or how much safety training is provided; the ultimate responsibility lies with the worker. The human factor is part of every accident or injury. The purpose of this paper is to identify electrical safety hazards and present ways to minimize or avoid their consequences. It is a guide for improving electrical safety and contains information about governmental regulations, industry-accepted standards and work practices. It presents ways to meet the standards and reduce the hazards. I. Introduction Electricity is very useful and has become essential in modern life. Electric power is used in houses, farms, factories, public places, and commercial establishment and practically in every working place for lighting, operating appliances and machines, heating, cooling, chemical process and transport etc. Electricity is a very good servant but a very dangerous master.

...Introduction Aircrafts require some form of electrical power to operate navigation, taxi, landing, strobe lights and other electronic systems. The electrical system consist of a battery and an alternator (you will find a generator on older type aircraft) to power the system and recharge the battery. You will also find fuses and switches and lights for indication purposes. Some electricity generators are used as backup power or other indication purposes. For example, a volt and/or ammeter are used for monitoring a change in voltage or current. However, this change in voltage or current could be brought about through the means of heat or light, which are electricity generators too. In a situation where primary power has failed, the aircraft storage batteries provide an emergency source of electrical power for operating electrical systems of an aircraft. All of these are connected through several meters (kilometres in large aircraft) of wire and connectors, attached to the airframe with insulation materials. In this report, I will be focusing on how these electricity generators are used in the various sections of the aircraft so as to understand the function they serve. I will be looking at four different methods of electricity generation. They are Magnetism and motion, Chemical Action, Light and Heat. Method of Electricity Generation 1 (Magnetism and Motion) It is important to note that magnetism itself does not create electricity. It requires...

...Electrical services design Institution Student name Introduction The need for electricity has been ever increasing. As well, the numbers of critical or sensitive loads have also increased. Today, the electricity transmission and distribution is greatly affected by this ever growing need. On the other hand, the consumer's demand has also been in a rising manner. These problems can be catered for by the use of energy storage devices, renewable energy and use of distributed generation. Micro-grid paradigm can deal effectively with the ever increasing electricity needs. This paradigm is bestowed with the ability to regulate the electricity flow. This is achieved through the generation and distribution mechanisms. Grid refers to different interconnection of different electricity transmission lines. The line does not necessarily need to be transmitting electricity of equal magnitudes. But the electricity of different magnitude that runs from the highest to the lowest magnitude possible. In short, the grid connects the consumers to the electricity supply utilities (Vittal & Ayyanar, 2013, pg. 162). The renewable energy integration into the main grid can take place in the distribution or at the transmission levels. The point at which integration takes place depends on the size or the scale of the electricity generation. Large generating stations directly feed the main grid. Unlike large generating stations, the small distributed generations feed the low or medium voltage lines...

...CHAPTER 1 INTRODUCTION 1. Background of Study Current Transformer (CT) is used to measure secondary current for metering and protection purposes. In another words, CT is used to transform a primary quantity in terms of its magnitude and phase to a secondary value such that in normal condition the secondary value is substantially proportional to the primary value. Much development by various manufacturers has been done to improve the output measurements. The appearance and development of the Optical Current Transformer (OCT) in the last few decades become much more interesting to replace the conventional CT in the power system operation. In the past 15 years, Optical CT has received a significant attention by a manufaturer to replace iron-core CT in electric power industry. This Optical CT is non conductive and lightweight which can give the end user easiness of installing and doing maintenance. 2. Literature Review In [1], the author describes the experimental comparison between conventional current transformer (CT) and the optical current transformer (OCT) especially in steady state response, transient response and impact of ambient temperature. Optical CT offered high accuracy in measuring the primary current for measuring or protection purposes compared to a conventional CT. Most of the studies regarding the Otpical CT lately are raised in order to demonstrate the advantages of the Optical CT in power system compared to...

...is not a bulb issue or an interior breaker issue. I also know that the power company has no reported outages in the area. I do know that the house was built in the 50’s and the electrical panel has not been upgraded since the home was built. Based on this information my hypothesis is that issue is within the main breaker outside the home. Due to the age of the home and electrical panel, it is likely a burnt out fuse that has caused all the lights to not work. Just to be sure I have tested the interior breakers of the house by flipping them to the off position and back on, still no lights. I also tested the exterior breaker by flipping it to the off position and back on, still no light. Now by replacing the fuse and switching on the lights I have solved the problem and have light throughout the house. From the research above I have found the problem was in fact a burnt out fuse at the main breaker of the exterior of the house. Question 2: It’s dinner time, I have all the ingredients ready to cook but when I go to turn the stove on nothing happens. I look at the knobs to double check they are on in the correct position and they are, in the on position. That’s when I observe that not only is the stove not working but in conjunction with the stove one half of the kitchen lights and electrical is not...
