The Danger Keep Out or Warning High Voltage signs on substation fences are there for your protection. Substations convert high-voltage power from transmission lines into lower voltage electricity to supply homes and businesses. Substation equipment is always exposed to high-voltage.�Some substation components could be energized at more than 100,000 volts.�The equipment within the substation is always under high voltage electrical load. Substation technicians, co-op linemen and maintenance crews are trained to work in high voltage situations and to recognize and avoid potential hazards in the substation. Just how high is the electric voltage ? Some of the pieces of equipment in the substation equipment could be energized at more than 100,000 volts. Remember, substation fences mark the danger zone for you. You are safe if you stay away from them. The signs on the substation fence say, "Danger - Keep Out" or "Warning - High Voltage" - and they mean it. They may not sound very friendly, but these signs can carry an important safety message: that fence is there for your protection. An electrical substation changes the extremely high voltage carried by the long-distance transmission lines into the lower distribution voltage that serves your home and business. To do this, the substation must have a direct feed from the transmission line into the substation structure. The equipment within the substation is always under high-voltage electrical load. Substation technicians, line technicians and maintenance crews are trained to work in high-voltage situations and to recognize and avoid potential hazards that exist in the substation. You can avoid these hazards by paying attention to the signs on the substation fencing; they mark the danger zone for you.
* a physical phenomenon associated with stationary or moving electrons and protons * energy made available by the flow of electric charge through a conductor; "they built a car that runs on electricity" * keen and shared excitement; "the stage crackled with electricity whenever she was on it" * Electricity is a property of certain subatomic particles (e.g. electrons / protons) which couples to electromagnetic fields and causes attractive and repulsive forces between them. Electricity gives rise to one of the four fundamental forces of nature, and is a conserved property of matter that can be quantified. In this sense, the phrase "quantity of electricity" is used interchangeably with the phrases "charge of electricity" and "quantity of charge." * This word names a branch or subdivision of physics, just as other subdivisions are named ?mechanics?, ?thermodynamics?, ?optics?, etc. * Provides power for lighting, appliances, and heating & cooling in a home. A meter records usage for billing by your local utility. * Electric current or power that results from the movement of electrons in a conductor from a negatively charged point to a positively charged point. * The flow of electrons. * Colloquially, electric charge and currents, viewed as a "fluid" which may be attached to matter or flow through it. The word came from "elektron," the Greek name of amber, one of the materials which when dry and lightly rubbed can attract small objects (by "static electricity"). The Greeks and Romans already knew about such attractions, but William Gilbert, who studied them, called such materials "electricks," and from that came the modern term. * Form of energy with magnetic, radiant and chemical effects. Electric current is created by a flow of charged particles (electrons). * The process of producing electrical energy from other forms of energy, also the amount of electric energy produced, usually expressed in kilowatt-hours (kWh) or megawatt-hours (MWh). Gross generation is the electrical output at the terminals of the generator, usually expressed in megawatts (MW). Net generation is gross generation minus the service power requirements of the generating station itself. * a fundamental phenomenon in nature seen in the attractions and repulsions of oppositely charged objects and utilized as a source of energy ion the form of a current * A form of energy produced by the flow of electrons through a material and some devices. * Metered electric power supplied by a central utility company to a residence via underground or aboveground power lines. Electricity generated on site for the exclusive use of a residence is estimated using the regression equations used to impute electricity. Since there are no volumetric measures of electricity as with the fossil fuels, electricity is measured as the amount of power used at any instant (demand expressed in W or kW) or as power used over a given time (consumption expressed in kWh). The heat equivalent for electricity that comes into the home is 3,412 Btu per kWh, but this is * A general term for the physical phenomena that arises from the interaction of electric charges. * ELECTRICITY is electric current used as a source of power. * Energy converted from natural resources or fuels and produced in a power plant. Electricity occurs in nature as lightning or static/friction. * A form of energy produced by the flow of particles of matter and consists of commonly attractive positively (protons [+]) and negatively (electrons [-]) charged atomic particles. A stream of electrons, or an electric current. * 1. The behavior of negative and positive charges (electrons and protons) due to their attraction and repulsion. 2. The flow of electrons; electric current. See Electrical (Electromagnetic) energy, Electric current. * Theosophy regards electricity not as a mere effect but as an entity or cosmic force named fohat, also spoken of distributively as the sons of fohat. In correlating electricity with these cosmic forces, we find the term given either to the one great energy from which the others differentiate, or to a particular one of such differentiations: eg, kundalini-sakti, which is characterized by spiral or serpentine motion and is thus related to electromagnetic phenomena, although kundalini might better be called vital electricity or magnetism, for electricity and magnetism are alter egos. * DIY, Electronics: The energy that is produced by a flow of electrons affected by an electromotive force that is produced either electrostatically, mechanically, chemically or thermally. * A form of energy that comes from the movement of electrons and protons. It can be produced by friction (as by rubbing wax with wool), by chemical action (as in a storage battery) or by induction (as in a dynamo ? an electric motor or generator). Electricity is used to produce light, heat, power, etc. Electricity moving in a stream, as through a wire, is called electric current. * The movement of electrons through a conductor. In conductors, such as gold, copper, and aluminum electrons can be easily forced to break orbit and flow to a new orbit around at a neighboring atom. Each electron leaving an atom is replaced by another in a musical chairs like dance. Electrons can only flow in a closed circuit. * The cause of all natural phenomena not known to be caused by something else. * a form of energy: electric current or power * A form of energy that flows along a path and can produce heat, light, magnetism, motion, or a chemical change. * Energy made by moving charged particles. * a. To set apart (a component, circuit, or system) from a source of electricity. b. To insulate or shield.
