Eur Ing Dr. Robert Brown

Dr. Brown of Fraser George and Associates, is presently helping in a matter concerning an explosion in a 33/11 KV substation where inherent electrical fault current protection devices have failed, provoking a study of the grading protection, i.e. fault current device discrimination of the substation electrical network. A grading protection scheme is the consecutive time/current settings of fault protection devices such as circuit breakers fuses etc., so that in the event of a

Dr Robert Brown (Robert) of Fraser George and Associates is presently working on a case concerning a user, accused of extracting electricity, where an electrical network supplier arrived to read an electrical consumption meter, allegedly found evidence of meter tampering and continued to leverage the user to pay monies the account whilst threatening to terminate the electrical supply. Presently Robert is attempting to source material to understand the legal procedure required

Pleased,.. a good result from a recent court hearing regarding a worker undertaking work in a road side excavation, stripped the insulation from an 11,000 volt cable 'assuming' it to be a low voltage 415 volt cable provoking an arc flashover and sustaining burns to hands and face !!! "Dear Robert Thank you for your assistance and support with this case, it is very much appreciated. I am pleased to advise that he judge has delivered his judgment and has found for both Defendan

Today, human life relies much on the discovery of electromagnetic induction by Michael Faraday and his associated work.. Michael Faraday FRS, was an English scientist who contributed to the study of electromagnetism and electrochemistry. His main discoveries include the principles underlying electromagnetic induction, diamagnetism and electrolysis. Faraday's law states: ‘The electromotive force around a closed path is equal to the negative of the time rate of change of the m

Alternating current (AC) is an electric current which periodically reverses direction and changes its magnitude continuously with time in contrast to direct current (DC) which flows only in one direction. Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions, fans and electric lamps into a wall socket. A common source

A transistor is a ‘semiconductor’ device used to amplify or switch electrical signals and power. The transistor is one of the basic building blocks of modern electronics. It is composed of semiconductor material (subsequently explained), usually with at least three terminals for connection to an electronic circuit. A voltage or current applied to one pair of the transistor's terminals controls the current through another pair of terminals. Because the controlled (output) powe

A circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by an overcurrent or short circuit. Its basic function is to interrupt current flow to protect equipment and to prevent the risk of fire. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. A circuit breaker is often referred to as an “Over Current Protection Device

A transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits. Fundamentally, a transformer comprises of two (2) coils of wire wound around a loop/ framework of metallic (iron/steel) material. The two (2) coils of wire are referred to as the ‘primary’ coil and ‘secondary’ coil. The metallic loop is referred to as the ‘core’ of the transformer. In this arrangement, in accordance with the laws of elect

This impresses me greatly, … the craftsmanship and engineering skill required and utilised to produce this crackshaft must have been immense. Reminds me of circumstance involving the mythical ‘Iraq Super gun’. Sheffield Forge Masters a specialist forging, casting and heavy engineering company still in existence on Brightside Lane in Attercliffe, Sheffield were contracted by an ‘intermediary’ to manufacture sections of a ‘pipe line’ to be used to convey ‘oil’ in Iraq. Around t

What is a short circuit, how does a short circuit manifest and what are the consequences? A short circuit (sometimes abbreviated to short or s/c) is an electrical ‘sub’ or ‘child’ circuit that abnormally evolves and allows an electrical current to flow along an unintended pathway. Generally a short circuit will have a very low electrical impedance (resistance). The manifestation of a short circuit, results in excessive current flowing through the circuit which can provoke dam

In the pantheon of 20th-century genius, there are a few stand-out figures: Albert Einstein, Alan Turing, Steven Hawking, and, without question, John von Neumann belongs in their company, even if many have no idea who he is. John von Neumann was one of the most influential figures of the 20th century. He is someone who has likely impacted your life more directly than just about any of the great minds of the past 150 years, touching on everything from quantum mechanics to clima

A solar panel, or photo-voltaic (PV) module, is an assembly of photo-voltaic cells mounted in a framework for installation. Solar panels use sunlight as a source of energy to generate direct current electricity. A collection of PV modules is called a PV panel, and a system of PV panels is called an array. Arrays of a photovoltaic system supply solar electricity to electrical equipment. A photovoltaic system typically includes an array of photovoltaic modules, an inverter, int

Schedule 4: UK nationally approved electricity meters Is your electricity meter old ? Is your electricity meter reading correctly? UK nationally approved electricity meters are approved under the Electricity Act 1989 and the pattern or construction of the meter type must conform to the requirements specified in the accompanying regulations. Formal approval certificates are issued by the Office for Product Safety and Standards (OPSS) to manufacturers of electricity meters. Th

A power outage (also called a power cut, a power out, a power blackout, power failure or a blackout) is a short-term or a long-term loss of the electric power to a particular area. There are many causes of power failures in an electricity network. Examples of these causes include faults at power stations, damage to electric transmission lines, substations or other parts of the distribution system, a short circuit, cascading failure, fuse or circuit breaker operation. Power fa

What are Surge Protective Devices? Surge Protective Devices (SPD) are used to protect sensitive electronic equipment such as, computers, televisions, washing machines and safety circuits, such as, fire detection systems and emergency lighting, from transient over voltages (voltage surges). It is now common for an SPD such as that shown in Figure 1, to be fitted within the consumer unit (distribution board) of an electrical system. What are transient over voltages? Transient o
