' Ionization Removal of an electron from an atom or molecule. The process of <br /> producing ions. The electrically charged particles produced by high-energy <br /> radiation, such as light or ultraviolet rays, or by the collision of particles <br /> ' during thermal agitation. <br /> Magnetic Field ("MF") The region in which the magnetic forces created by a permanent magnet or <br /> by a current-carrying conductor or coil can be detected. The field that is <br /> ' produced when current flows through a conductor or antenna. <br /> Mitigate To lessen the severity of or alleviate the effects of. <br /> Neutral to Earth The term NEV is used to describe a measurable level of voltage which may <br /> Voltage ("NEV") occur between a metal object and the adjacent floor or earth. <br /> Oxide A compound of oxygen with one other more positive element or radical. <br /> ' Ozone A form of oxygen in which the molecule is made of three atoms instead of <br /> the usual two. <br /> Raptor A member of the order Falconiformes, which contains the diurnal birds of <br /> prey, such as the hawks,harriers,eagles,and falcons. <br /> Sediment Material deposited by water,wind,or glaciers. <br /> Stray Voltage A condition that can occur on the electric service entrances to structures <br /> from distribution lines, not transmission lines. More precisely, stray voltage <br /> is a voltage that exists between the neutral wire of the service entrance and <br /> grounded objects in buildings such as barns and milking parlors. <br /> ' Transmission lines do not, by themselves, create stray voltage because they <br /> do not connect to businesses or residences. Transmission lines, however, <br /> can induce stray voltage on a distribution circuit that is parallel to and <br /> immediately under the transmission line. <br /> Substation A substation is a high voltage electric system facility. It is used to switch <br /> generators, equipment, and circuits or lines in and out of a system. It also is <br /> used to change AC voltages from one level to another. Some substations <br /> are small with little more than a transformer and associated switches. <br /> Others are very large with several transformers and dozens of switches and <br /> other equipment. <br /> Ultraviolet Radiation A portion of the electromagnetic spectrum with wavelengths shorter than <br /> visible light. <br /> Voltage Electric potential or potential difference expressed in volts. A unit of <br /> electrical pressure, electric potential or potential difference expressed in <br /> volts. The term used to signify electrical pressure. Voltage is a force that <br /> causes current to flow through an electrical conductor. The voltage of a <br /> circuit is the greatest effective difference of potential between any two <br /> conductors of the circuit. <br /> ' Voltage Drop The difference in voltage between two points; it is the result of the loss of <br /> electrical pressure as a current flows through a resistance. <br /> Waterfowl A bird that frequents water; especially a swimming game bird (as a duck or <br /> ' goose) as distinguished from an upland game bird or shorebird. <br /> Wetland Wetlands are areas that are periodically or permanently inundated by surface <br /> or ground water and support vegetation adapted for life in saturated soil. <br /> ' Wetlands include swamps,marshes, bogs and similar areas. <br /> ' Orono Project June 7,2011 <br /> MPUC Docket No. E002/TL-11-223 75 <br />
