The ANSI/NETA Standard for Electrical Commissioning Specifications for Electrical Power Equipment and Systems

Scope
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.

Three voltage classes of equipment are detailed within the ANSI/NETA ECS

  • 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)

BRIDGING THE GAP FROM ACCEPTANCE TESTING TO COMMISSIONING

Acceptance Testing
The systematic process of performing field tests and inspections that are available to assess the suitability for initial energization and final acceptance of electrical power equipment and systems.

Electrical Commissioning
The systematic process of documenting and placing into service newly-installed or retrofitted electrical power equipment and systems.

"It is this need and requirement to bridge the gap between acceptance testing and electrical commissioning that completes the electrical system overall acceptance process. Again, from individual component testing to assurance that all integral components are functioning as a complete unit within design requirements and manufacturer's published data; along with the correct operation of all interlock safety devices for fail-safe functions; and the correct operation of all sensing devices, alarms, and indicating devices."
