ANSI/NETA MTS, Standard for Maintenance Testing Specifications for Electrical Power Equipment and Systems, 2015 Edition, has been revised. ANSI/NETA MTS-2019 was approved by ANSI as an American National Standard on February 7, 2019. The revised edition of ANSI/NETA MTS, scheduled for release in March 2019, features new content including Online Partial Discharge Survey for Switchgear and Frequency of Power System Studies. The revised edition will be available in the NETA Bookstore at www.netaworld.org, where a complimentary PDF copy can be downloaded or a printed copy ordered.
ANSI/NETA MTS contains specifications for suggested field tests and inspections to assess the suitability for continued service and reliability of electrical power equipment and systems. The purpose of these specifications is to assure that tested electrical equipment and systems are operational and within applicable standards and manufacturers’ tolerances, and that the equipment and systems are suitable for continued service.
ANSI/NETA ECS, Standard for Electrical Commissioning of Electrical Power Equipment and Systems, 2015 Edition, was approved as an American National Standard on December 3, 2014. This standard is available for purchase in the NETA Bookstore at www.netaworld.org. A project intent notification was published in ANSI’s Standards Action on May 18, 2018, with a 30-day public review period that closed June 18, 2018. An initial ballot and 45-day public comment period is scheduled to begin in April 2019.
ANSI/NETA ECS describes the systematic process of documenting and placing into service newly installed or retrofitted electrical power equipment and systems. This document shall be used in conjunction with the most recent edition of ANSI/NETA ATS, Standard for Acceptance Testing Specifications for Electrical Power Equipment and Systems. The individual electrical components shall be subjected to factory and field tests, as required, to validate the individual components. It is not the intent of these specifications to provide comprehensive details on the commissioning of mechanical equipment, mechanical instrumentation systems, and related components.
Voltage classes addressed include:
- Low-voltage systems (less than 1,000 volts)
- Medium-voltage systems (greater than 1,000 volts and less than 100,000 volts)
- High-voltage and extra-high-voltage systems (greater than 100 kV and less than 1,000 kV)
- ASHRAE, ANSI/NETA ATS, NECA, NFPA 70E, OSHA, GSA Building Commissioning Guide
This document is scheduled for release as a reaffirmed or revised standard in spring 2020. Those interested in participating in the revision process should contact the NETA office for more information. Initial review work began in the spring of 2018.
ANSI/NETA ETT, Standard for Certification of Electrical Testing Technicians, 2015 Edition, has been revised as an American National Standard. ANSI/NETA ETT-2018 was approved by ANSI as an American National Standard on February 22, 2018. The revised edition was released in March 2018. It is available now in the NETA Bookstore at www.netaworld.org, where a complimentary PDF copy can be downloaded or a printed copy ordered.
ANSI/NETA ETT establishes minimum requirements for qualifications, certification, training, and experience for the electrical testing technician. It provides criteria for documenting qualifications for certification and details the minimum qualifications for an independent and impartial certifying body to certify electrical testing technicians.
ANSI/NETA ATS covers suggested field tests and inspections for assessing the suitability for initial energization of electrical power equipment and systems. The purpose of these specifications is to assure that tested electrical equipment and systems are operational, are within applicable standards and manufacturers’ tolerances, and are installed in accordance with design specifications.
This document is scheduled for release as a revised standard in the spring of 2021. Those interested in participating in the revision process should contact the NETA office for more information, or see www.netaworld.org.
