18、 Foreword (This Foreword is not part o f American National Standard 62.61-1993) This standard covers gas tube surge arresters to be used for the limitation of voltage surges due to lightning or power disturbances on wire line telephone circuits. The purpose of the standard is to serve manufacturers
19、and purchasers of gas tube surge amesters by providing technical guidance to ensure the satisfactory operation of these surge arresters in the application intended. Suggestions for improvement of this standard will be welcome. They should be sent to the National Electrical Manufacturers Association,
20、 1300 North 17th Street, Ross, Virginia 22209. This standard was processed and approved for submittal to ANSI by the American National Standards Committee on Surge Arresters, C62. Committee approval of the standard does not necessarily imply that all committee members voted for its approval. A t the
21、 time it approved this standard, the C62 Committee had the following members: Secretariat: National Electrical Manufacturers Association scope: J. L. Koepfinger, Chairman J.

30、 be identified, and the classification shall apply only when the arresters are used in those protectors. 6 Design test criteria The design tests described in 6.1 through 6.7 provide standardized methods for making single observations of a specified property of an arrester. These properties usually v
31、ary from measurement to measurement, making it necessary to provide statistical descriptions of the property in order to compare arresters. The following statistical procedure shall be used to describe any property that has been determined to have important statistical aspects: A product sample shal
32、l be selected in a manner consistent with the needs of the purchaser. A sufficient number of arresters shall be tested and the characteristics in question measured as described in the applicable design tests until the parameters of the underlying statistical distribution are determined within confid
33、ence limits specified by the manufacturer or purchaser. Values relating to the product sample such as, but not limited to, mean, medium, maximum, minimum, and standard deviation may then be started. The tests in 6.1 through 6.7 should be conducted on the arrester as required by the application. 6.1
34、Direct current breakdown voltage For arresters that have not been subjected to high energy tests, the values of direct current (dc) breakdown voltage for a given polarity shall be within the limits specified in table 1 of this standard when measured in accordance with 4.1 of ANWIEEE C62.31-1987. Whe
35、n applicable, the average value shall be greater than the minimum average shown in table 1.
