3、nferenceTest ProceduresApproved 1/25/89American National Standards Institute, Inc.iiForeword(This Foreword is not part of American National Standard C37.53.1-1989.)The High Voltage Apparatus Coordinating Committee (HVACC) was established July 24, 1973 by the Electrical andElectronic Technical Adviso

4、ry Board of the American National Standards Institute. In 1982, the advisory board wassuperseded by the Electrical and Electronic Standards Board. The responsibility assigned to HVACC was to reviewand evaluate existing ANSI-approved standards and other related standards for the purpose of developing

5、 a “DraftStandard” for unit substations and recommendations for (1) correlating the requirements of these standards and (2)adding requirements to these standards appropriate for product evaluation.This standard results from the evaluation of existing ANSI-approved standards and from the need to add

6、requirementsto these standards for the evaluation and conformance certification of high-voltage motor-starter fuses.The intent of this standard is to allow qualification of high-voltage motor-starter fuses for use in accordance with theAmerican National Standard National Electrical Code, ANSI/NFPA 7

7、0-1987. However, this standard does not coverinstallations under the exclusive control of electric utilities and is not intended to cover application, installation, oroperation of high-voltage motor-starter fuses.This 1989 revision of the standard was developed to modify Section 5. (Production Monit

8、oring) and to update othersections.Suggestions for improvement of this standard are welcome. They should be sent to the National ElectricalManufacturers Association, 2101 L Street, NW, Washington, DC 20037.iiiThis standard was processed and approved for submittal to ANSI by Accredited Standards Comm

18、s standard covers the conformance test procedures for alternating-current high-voltage motor-starter fuses coveredin the applicable American National Standards listed in 2.1. High-voltage motor-starter fuses are backup, current-limiting fuses used in conjunction with high-voltage Class E2 motor star

19、ters.This standard does not cover installations under the exclusive control of electric utilities for the purposes ofcommunication or metering, or for the generation, control, transformation, transmission, and distribution of electricenergy located in buildings used exclusively by utilities for such

20、 purposes, or located outdoors on property owned orleased by the utility or on public highways, streets, roads, and the like, or located outdoors by established rights onprivate property.1.1 GeneralThese tests shall be used to demonstrate that the motor-starter fuses being tested conform with the sp

21、ecified ratings andcharacteristics. The standard is designed to cover a product that can be used with Class E2 controllers (fused) asdescribed in Table 27.1 and elsewhere in the American National Standard Safety Standard for High Voltage IndustrialControl Equipment, ANSI/UL 347-1985.1.2 Insulating E

22、valuationInsulating materials for use in motor-starter fuses shall be evaluated with respect to their acceptability for the particularapplication. When a material is evaluated, the mechanical strength, dielectric properties, insulation resistance, and heatresistance qualities of the material are con

23、sidered in conjunction with actual service conditions. The degree to whichthe fuse is enclosed or protected and any other features having a bearing on electrical shock or dielectric failure arealso tested. All of these factors are considered with respect to thermal aging.2AMERICAN NATIONAL STANDARD
