ANSI/NETA ATS-2017: Standard Acceptance Testing Specifications Electrical Power Equipment Systems

Electrical power equipment is intricate and nuanced, and in the event of failure, the system can perform improperly and introduce hazards to human life. Therefore, the installation, design, construction, operation, and maintenance of electrical power systems has always been aided by standardization. These issues are already within the scope of standards developed and published by IEEE, the National Electrical Manufacturers Association (NEMA), and other organizations.

Similarly, ANSI/NETA ATS-2017: Standard for Acceptance Testing Specifications for Electrical Power Equipment and Systems covers suggested field tests and inspections to assess the suitability for initial energization and final acceptance of electrical power equipment and systems. Since the acceptance testing of different electrical power systems can widely vary, many criteria are used in establishing the exact equipment for testing, and the document outlines its structure to better assist the user in finding guidance for his or her particular application.

ANSI/NETA ATS-2017 was developed and published by the InterNational Electrical Testing Association (NETA), an ANSI-accredited standards developing organization whose vision is “to set the global standard for electrical power system testing through its technical competence, world-class programs, and consensus standards.” NETA’s scope of standards activity differs from that of IEEE and NEMA, but standards by these other organizations generally appear as references in NETA publications, such as they do in ANSI/NETA ATS-2017.

In adhering to the specifications of ANSI/NETA ATS-2017, users should be able to assure that tested electrical equipment and systems are operational, are within applicable standards and manufacturer’s tolerances, and are installed in accordance with design specifications.

ANSI/NETA ATS-2017 updates and supersedes the previous 2013 edition of the same set of specifications, and, as the standard addresses a wide range of applications, it contains numerous changes throughout its expansive pages. To aid the user with compliance, any part of the standard that has been affected by the insertion, deletion, or alteration of text is marked with a black vertical line to the left of one of these alterations.

Some revisions to ANSI/NETA ATS-2017 include:

  • Updated references.
  • New information added to test report and test decal, such as minimum requirements for humidity and the identification of the testing technician.
  • The addition of arc-flash hazard PPE category determination during arc-flash hazard analysis.
  • Changes to the process of visual and mechanical inspection of switchgear and switchboard assemblies.
  • The addition of electrical tests for switchgear and switchboard assemblies.
  • Changes to inspection and test procedures of transformers, dry-type, air-cooled, large; transformers, liquid-filled; cables, low-voltage, 600-volt maximum; cables, medium- and high-voltage.
  • However, these few examples only shed some light on the multitude of alterations that are present within the ANSI/NETA ATS-2017 document.

ANSI/NETA ATS-2017: Standard for Acceptance Testing Specifications for Electrical Power Equipment and Systems is available on the ANSI Webstore.
