`
`(3) Any product whose sole purpose is to act as an obstruction
`to the path of the animal. A barrier may have electrical in—
`sulating properties, but by design and application, its use is
`limited to blocking an animal’s passage or an animal’s contact
`with energized conductors or equipment.
`(SUB/PE) 1264-1993
`(4) An obstruction composed of suitable construction and ma-
`terials or a time delay mechanism that imposes a delay for an
`intended purpose.
`(PE/NP) 692—1997
`barrier grid (charge-storage tubes) A grid, close to or in con—
`tact with a storage surface, which establishes an equilibrium
`voltage for secondary—emission charging and serves to mini—
`mize redistribution. See also: charge—storage tube.
`(ED) 158—1962w, [45]
`barrier layer (fiber optics) In the fabrication of an optical fiber,
`a layer that can be used to create a boundary against OH‘ ion
`diffusion into the core. See also: core.
`
`(StleO) 812v1984w
`barrier transaction (1) Transaction that is guaranteed to be-
`come Visible to other observers after all transactions created
`before it have become visible.
`(C/BA) 896.3—1993w
`(2) A transaction that ensures that all previously generated
`write transactions have the global appearance of having been
`written to memory. This is used before signaling another non-
`coherent unit, or one in a different coherence domain, that
`the data is available. In some systems, this is an explicit bus
`transaction that will be treated specially by the bus bridges
`(e.g., that may not return a response until all write buffers for
`the unit are flushed). For buses that delay the write-response
`until write bus transactions have been adequately completed,
`a separate barrier transaction is not needed since the effect of
`a barrier can be achieved by waiting for all outstanding write—
`responses. Synonym: write barrier.
`(C/MlVI) 1212.1-1993
`barrier wiring techniques (coupling in control systems) Those
`wiring techniques which obstruct electric or magnetic fields,
`excluding or partially excluding the fields from a given cir-
`cuit. Barrier techniques are often effective against electro-
`magnetic radiation also. In general, these techniques change
`the coupling coefficients between wires connected to a noise
`source and the signal circuit. Example: placement of signal
`lines within steel conduit to isolate them from an existing
`magnetic field. See also: suppressive wiring techniques; com-
`pensatory wiring techniques.
`(IA/ICTL) 518—1982r
`barring hole (rotating machinery) A hole in the rotor to permit
`insertion of a pry bar for the purpose of turning the rotor
`slowly or through a limited angle. See also: rotor.

`
`(6) (high-voltage fuse) The supporting member to which the
`insulator unit or units are attached.
`(SWG/PE) C37.40—1993, C37.100—l992
`(7) (pulse terminology) The two portions of a pulse wave.
`form which represents the first nominal state from Which a
`pulse departs and to which it ultimately returns.
`(IM/WM&A) 194-1977w
`base active power (synchronous generators and motors) The
`total (generator) output or (motor) input power at base voltage
`and base current with a power factor of unity.
`base address (1) (computers) An address used as a reference
`point to which a relative address is added to determine the
`address of the storage location to be accessed. See also: in—
`dexed address; relative address; selfrelative address.
`(C) 61012—1990, 610.10—1994w
`(2) A given address from which an absolute address is derived
`by combinau'on with a relative address. Synonyms: reference
`address; presumptive address; constant address.
`(C)
`[20], 610.10—1994w, [85]
`base address register A register used in an operand field of a
`processor instruction with a specified offset, the sum of which
`points to a data value within a data structure to be used by
`the instruction. See also: base register.
`(C) 610.10—1994w
`base ambient
`temperature (power distribution, under-
`ground cables) (cable or duct) The no-load temperature in a
`group with no load on any cable or duct in the group.
`(PE) [4]
`base apparent power (1) (ac rotating machinery) (basic per-
`unit quantities for ac rotating machines) A reference value
`expressing an electrical power rating of the machine. Notes:
`1. Base apparent power may be either input or output power,
`and the numerical value may be either real power—watts
`(W)—or
`total
`apparent electrical power—voltamperes
`(VA)—~depending upon machine type. Base apparent power
`is usually expressed in voltamperes, but any consistent set of
`units may be used. For synchronous generators, induction
`generators, and synchronous motors, base apparent power is
`the total apparent electrical at rated voltage and rated current.
`In induction motors (preferred method), base apparent power
`is numerically equal to the rated power output. For induction
`motors (alternate method), base apparent power is the total
`apparent electrical power at rated voltage and rated current.
`2. When the alternate method is used it should be identified
`as “input voltampere based.”
`(EM/PE) 86—1987w
`(2) (synchronous generators and motors) The total rated
`apparent power at rated voltage and rated current. Note: Base
`apparent power is usually expressed in volt-amperes, but any
`consistent set of units may be used.
`86-1961
`base assertion An assertion that is required to be tested for
`required features and for implemented conditional feaures.
`(C/PA) 1326.2-1993W, 1328-1993w, 13210-1994,
`20031-1992, 1328.2-1993w
`baseband (carrier or subcarrier wire or radio transmission
`system) The band of frequencies occupied by the signal be-
`fore it modulates the carrier (or subcarrier) frequency to form
`the transmitted line or radio signal. Note: The signal in the
`baseband is usually distinguished from the line or radio signal
`by ranging over distinctly lower frequencies, which at the
`lower end relatively approach or may include direct current
`(zero frequency). In the case of a facsimile signal before mod-
`ulation on a subcairier, the baseband includes ‘direct current.
`See also: facsimile transmission.
`(BT/COM/PE/AV) [34], 168-1956w, 599—1985w
`baseband coaxial system (1) A baseband system employing
`coaxial cables as a data transmission medium. At any point
`on the medium only one information signal at a time can be
`present without disruption. Contrast: baseband twisted—pair
`system.
`(C) 610.7-1995
`(2) A system whereby information is directly encoded and
`impressed upon the transmission medium. At any point on
`the medium only one information signal at a time can be
`present without disruption.
`(C/LM) 8023—1998
`
`bar, rotor See: rotor bar.
`bar-type current transformer One that has a fixed and straight
`single primary winding turn passing through the magnetic
`circuit. The primary winding andsecondary winding(s) are
`insulated from each other and from the core(s) and are assem-
`bled as an integral structure.
`(PE/TR) C57.13—l993, [57]
`base (1) (number system) An integer whose successive powers
`are multiplied by coefficients in a positional notation system.
`See also: radix; positional notation.
`(C) 162—1963w
`(2) (rotating machinery) A structure, normally mounted on
`the foundation, that supports a machine or a set of machines.
`In single—phase machines rated up through several horse-
`power, the base is normally a part of the machine and supports
`it through a resilient or rigid mounting to the end shields.
`(PE) [9]
`(3) (electron tube or valve) The part attached to the enve—
`lope, carrying the pins or contacts used to connect the elec—
`trodes to the external circuit and that plugs into the holder.
`See also: electron tube.

`(S) (transistor) A region that lies between an emitter and a
`collector of a transistor and into which minority carriers are
`
`injected. See also: transistor. (ED/IA) 216-1960w, [12]
