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......

Electrical for Hvacs

...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......

Electrical Fundamentals

...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......

...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.

Electrical Design

...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......

Electrical conductivity Conductivity, = 1/ = l/RA ( -m)-1 Band Theory Electrons occupy energy states in atomic orbitals When several atoms are brought close to each other in a solid these energy states split in to a series of energy states (molecular orbitals). The spacing between these states are so small that they overlap to form an energy band. Band Theory The furthest band from the nucleus is filled with valence electrons and is called the valence band. The empty band is called the conduction band. The energy of the highest filled state is called Fermi energy. There is a certain energy gap, called band gap, between valence and conduction bands.  Primarily four types of band structure exist in solids. Band Theory In metals the valence band is either partially filled (Cu) or the valence and conduction bands overlap (Mg). Insulators and semiconductors have completely filled valence band and empty conduction band. It is the magnitude of band gap which separates metals, semiconductors and insulators in terms of their electrical conductivity. The band gap is relatively smaller in semiconductors while it is very large in......

Similarly, 8V source is removed to calculate currents due to 3V supply. a) Voltage across the 18 ohm resistor is 4.6872 volts and current across is 0.2604 amperes; b)Current in the 8V generator is 1.667 amperes; c) Current in the 3V generator is 0.656 amperes. (John, 2003) Question 1.3 a) Transformers are electrical devices that play a very vital and key role in electrical power distribution and transmission systems. They are static devices, that is, they do not have any moving components. Transformers utilize one of the most basic forces in nature, the electromagnetic force to convert alternating electrical energy of one power rating to another power rating, but do not change the frequency of the primary electrical energy. Voltage transformers are used to lower or raise the magnitude of the incoming voltage and accordingly current increases or decreases. Electromagnetic induction is used to perform this conversion, more specifically mutual induction. In a simple voltage transformer, two coils are present that have common magnetic flux in between...
