19、 Committee (SPD), of the IEEE Power Engineering Society developed those sections of this standard which fall within the scope of IEEE. SPD maintains close liaison with the American National Standards Institute Committee on Surge Arresters, ANSI C62, which is organized specifically to develop consens
20、us standards. A delegation of SPD members participated in the activities of ANSI C62 which included inputs to SPD and development of ratings and dimensional information included in this standard. In the judgment of IEEE, this information is reasonably consistent with good engineering practice. This
21、standard constitutes by reference only an integral part of the National Electrical Manufacturers Association (NEMA) Standards Publication for Surge Arresters, NEMA LA 1-1976. Prior to and during development of this edition close liaison has been maintained with the International Electrotechnical Com
22、missions surge arrester standardizing activity with the result that contributions have been made to development of international specifications. It is the policy of both the Institute of Electrical and Electronics Engineers and American National Standards Committee C62 to maintain this standard curr
23、ent with the state of the technology. Comments on this standard, as well as suggestions for additional material that should be included are invited.

Scope This standard applies to surge-protective de-vices designed for repeated limiting of voltage surges on 50 Hz or 60 Hz power circuits by passing surge discharge current and subse-quently automaticall
38、y interrupting the flow of follow current. This standard applies to devices for separate mounting and to those supplied integrally with other equipment. 2. Definitions The following definitions apply specifically to surge arresters and do not necessarily cover other applications. 2.1 surge arrester.
39、 A protective device for limiting surge voltages on equipment by dis-charging or bypassing surge current; it prevents continued flow of follow current to ground, and is capable of repeating these functions as specified. NOTE: Hereafter, the term arrester as used in this standard shall be understood
40、to mean surge arrester. 2.2 valve element. A resistor that, because of its nonlinear current-voltage characteristic, limits the voltage across the arrester terminals during the flow of discharge current and contributes to the limitation of follow current at normal power-frequency voltage. 2.3 expuls
41、ion element. A chamber in which an arc is confined and brought into contact with gas-evolving material. 2.4 series gap. An intentional gap(s) between spaced electrodes: it is in series with the valve or expulsion element of the arrester, substan-tially isolating the element from line or ground, or b
42、oth, under normal line-voltage conditions. 2.5 valve arrester. An arrester that includes a valve element. 2.6 expulsion arrester. An arrester that includes an expulsion element. 2.7 indoor arrester. An arrester that, because of its construction, must be protected from the weather. 2.8 outdoor arrest
43、er. An arrester that is de-signed for outdoor use. 2.9 classification of arresters. Arrester classifi-cation is determined by prescribed test require-ments. These classifications are: station valve arrester intermediate valve arrester distribution valve arrester distribution expulsion arrester secon
44、dary valve arrester NOTE: See 5.2 for the test requirements. 2.10 terminals. The conducting parts provided for connecting the arrester across the insulation to be protected. 2.10.1 ground terminal. The conducting part provided for connecting the arrester to ground. 2.10.2 line terminal. The conducti
45、ng part provided for connecting the arrester to the circuit conductor. NOTE: When a line terminal is not supplied as an integral part of the arrester, and the series gap is obtained by providing a specified air clearance between the line end of the arrester and a conductor, or arcing electrode, etc,
46、 the words line terminal used in the definition refer to the conducting part that is at line potential and that is used as the line electrode of the series gap. 2.11 grading or control ring. A metal part, usually circular or oval in shape, mounted to modify electrostatically the voltage gradient or
47、distribution. 2.12 vent. An intentional opening for the escape of gases to the outside. 2.13 deflector. A means for directing the flow 7 ANSI/IEEE C62.1-1981 IEEE STANDARD FOR SURGE ARRESTERS designated by a combination of two numbers. The first, an index of the wave front, is the virtual duration o
48、f the wave front in micro-seconds as defined in 2.30. The second, an index of the wave tail, is the time in micro-seconds from virtual zero to the instant at which one-half of the crest value is reached on the wave tail. Examples are 1.2/50 and 8/20 waves. 2.28.2 The wave shape of a rectangular impu
49、lse of current or voltage is designated by two numbers. The first designates the min-imum value of current or voltage which is sustained for the time in microseconds desig-nated by the second number. An example is the 75 A 1000 jus wave. 2.29 virtual zero point (of an impulse). The intersection with the zero axis of a straight line drawn through points on the front of the current wave at 10% and 90% crest value, or through points on the front of the voltage wave at 30% and 90% crest value. 2.30 virtual duration of wave front (of an
