Standard for Acceptance Testing Specifications for Electrical Power Equipment and Systems

ANSI/NETA ATS-2009: Standard for Acceptance Testing Specifications for Electrical Power Equipment and Systems

Ensure the reliability and safety of critical electrical power systems with ANSI/NETA ATS-2009, an industry-leading standard that provides comprehensive specifications for acceptance testing. This essential document is the cornerstone for verifying that newly installed or modified electrical power equipment and systems perform as designed and meet stringent safety requirements before energization.

What is ANSI/NETA ATS-2009?

ANSI/NETA ATS-2009, developed by the InterNational Electrical Testing Association (NETA), outlines proven procedures for the acceptance testing of electrical power equipment and systems. Its primary purpose is to establish a uniform and authoritative benchmark for testing, ensuring that all components function correctly and safely, thereby minimizing risks and operational disruptions.

Scope & Purpose

This standard governs the systematic testing of electrical power equipment and systems upon installation or modification, prior to commissioning. It defines the required tests, procedures, and reporting formats necessary to verify performance, safety, and compliance with design specifications. While it covers a broad range of equipment from low voltage to high voltage, it specifically excludes ongoing maintenance testing, which is addressed by separate NETA standards.

Who Must Comply?

• • Primary audience: Electrical Engineers, Test Technicians, Commissioning Agents, Project Managers, and Maintenance Electricians involved in the installation, verification, and commissioning of electrical power systems.
• • Industries affected: Power Generation, Transmission, and Distribution; Oil and Gas; Manufacturing; Data Centers; Healthcare; Education; and Commercial Real Estate.
• • Compliance nature: Compliance is typically voluntary but is frequently mandated by project specifications, contracts, and owner requirements to ensure quality and safety.
• • Enforcement: Compliance is often verified by the owner's representative, project engineers, or third-party commissioning agents who review test reports against the standard's requirements.

Key Requirements Overview

• • The standard requires rigorous testing of newly installed electrical power equipment to confirm its operational integrity and safety compliance.
• • Professionals must ensure that all testing personnel and organizations meet specific qualification and competency criteria.
• • Key provisions include detailed test procedures for various equipment types, such as switchgear, transformers, cables, and protective devices.
• • It mandates the use of calibrated test equipment and the proper documentation of all test results in a comprehensive report.
• • Adherence to strict safety protocols during all testing phases is a fundamental requirement.
