ANSI/NETA MTS-2019

Standard for Maintenance Testing Specifications for Electrical Power Equipment & Systems

Specifies field tests and inspections used to assess the suitability for continued service and reliability of electrical power equipment and systems.


ANSI/NETA ATS-2021

Standard for Acceptance Testing Specifications for Electrical Power Equipment and Systems

The NETA Acceptance Testing Specifications was developed for use by those responsible for assessing the suitability for initial energization of electrical power equipment and systems and to specify field tests and inspections that ensure these systems and apparatus perform satisfactorily, minimizing downtime and maximizing life expectancy.


ANSI/NETA ATS-2017

Standard for Acceptance Testing Specifications for Electrical Power Equipment and Systems

It is the purpose of these specifications 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. These specifications cover the suggested field tests and inspections that are available to assess the suitability for initial energization and final acceptance of electrical power equipment and systems.  NETA has developed the ANSI/NETA ATS to assist in the pre-energization inspection and startup of power equipment and systems. Electrical testing firms, architects, engineers, equipment owners, inspection authorities, and others should reference this document when inspecting power equipment after it is installed in the field. This type of testing identifies any damage that occurred during shipping, checks to assure that installation occurred in accordance with designs, and that all components are connected and function as part of a system as well as individually.  Acceptance tests are not manufacturers' factory tests. They comprise those tests necessary to determine that the electrical equipment has been selected in accordance with the engineer's requirements, installed in accordance with applicable codes and installation standards, and perform in accordance with their design and setting parameters. The ANSI/NETA Standard for Acceptance Testing Specifications for Electrical Power Equipment and Systems assists designers, specifiers, architects, and users of electrical equipment and systems in specifying required tests on newly-installed power systems and apparatus, before energizing, to ensure that the installation and equipment comply with specifications and intended use as well as with regulatory and safety requirements.
