�-�Refers to an equal loading of the phases in a polyhphase system (current and phase angle).

�-�A polyphase system in which both the currents and voltages are symmetrical.

�-�A device that by means of inductance, capacitance, or resistance, singly or in combination, limits the lamp current of a fluorescent or high intensity discharge lamp. It provides the necessary circuit conditions (voltage, current and wave form) for start

�-�The data carrying capacity of a transmission path, measured in bits or bytes per second.

�-�A group of electrical devices, usually transformers or capacitors, connected in a way to increase capacity.

�-�A reference impulse (voltage) insulation strength expressed in terms of the peak value of the withstand voltage of a standard impulse voltage wave. It is used to express the ability of electrical equipment such as transformers to withstand certain levels

�-�A design voltage level for electrical apparatus that refers to a short duration (1.2 x 50 microsecond) crest voltage and is used to measure the ability of an insulation system to withstand high surge voltage.

�-�A combination of two or more chemical cells connected together electronically to produce electrical energy.

�-�A contained with a base and walls for holding several cells or batteries.

-�A fusing device frequently used to protect transformers and downstream devices. A Bay-O-Net fuse may include a Partial Range Current Limiting Fuse in series with n under oil fuse link.

�-�In wireless networking, a beacon is a packet sent by a connected device to inform other devices of its presence and readiness.

�-�With regard to outdoor light, the angle between the two directions in a plane in which the intensity is equal to a stated percentage of the maximum beam intensity. The percentage is typically 10% for floodlights and 50% for roadway luminaries.

�-�Refers to a lineman's climbing belt.

-�The current used as a bias quantity in a biased relay.

-�A relay in which the characteristics are modified by the introduction of some quantity, and which is usually in opposition to the actuating quantity.

�-�Any road, street, path or way that is specifically designated as being open to bicycle travel, regardless of whether such facilities are designed for the exclusive use of bicycles.

-�1) See Basic Insulation Level. 2) See Basic Impulse Level.

�-�The complete interrupting of load to an electric utility customer or group of customers to reduce overall load on the system.

�-�The act of installing fiber optic cable into a duct using air pressure.

�-�A wireless computing and telecommunications specification that defines how mobile personal computing devices work with each other and with regular computers and phone systems within a close range.

�-�The permanent joining of metallic parts to form an electrically conductive path that will ensure electrical continuity and the capacity to conduct any current to be present in a safe manner.

�-�A lineman that moves from job to job.

�-�A charge applied to a battery which is already near a state of full charge, usually of short duration.

-�A current transformer whose primary winding is in series with the catenary and secondary winding in the return conductor of a classically-fed A.C. overhead electrified railway.

-�Refers to a reduction of voltage on the system. This effectively dims the lights. Systems in the eastern parts of the U.S. where networks are integrated use brownouts as a means of conserving energy.

�-�The act of lowering the voltage.

�-�A basket or platform that supports one or more linemen attached to a boom of a truck.

�-�An aerial lift truck used to lift men high enough to work on overhead lines

�-�Conductors and cables used in commercial building construction.

-�The outer enclosure of a light source; usually glass or quartz.

�-�The outer enclosure of a light source; usually glass or quartz.

�-�Heavy line used to pull wire or cable into a conduit or into an overhead configuration.

-�A reel device used to hold tension during the wire installation process.

-�A term applied to a number of wires twisted together in one direction in one operation without regard to their geometric arrangement.

�-�Multiple cables used to form one phase of an overhead circuit.

�-�Buried Urban Residential Distribution.

�-�Load imposed by an electronic or electrical device on the measured input circuit, expressed in volt-amps.

�-�Refers to the system of electric utility equipment installed below grade

-�A conductor, which may be a solid bar or pipe, normally made of aluminum or copper, used to connect one or more circuits to a common interface. An example would be the bus used to connect a substation transformer to the outgoing circuits.

-�An insulator having a conductor through it, used to connect equipment to a power source.
