When selecting a NETA testing company, look beyond the testing report itself. Evaluate the company’s field experience, technical capabilities, safety record, qualifications of testing personnel, engineering resources, and ability to support corrective actions identified during testing.

The best providers understand the entire electrical system rather than simply performing tests. A company that also performs engineering studies, commissioning, maintenance, modernization, and troubleshooting can often provide more practical recommendations because they understand how equipment performs throughout its lifecycle.

Electrical infrastructure decisions rarely exist in isolation. Equipment design affects commissioning. Testing results influence maintenance strategies. Engineering studies drive modernization decisions. Reliability programs impact long-term asset management.

Working with a company that supports the entire electrical asset lifecycle often results in better coordination, fewer knowledge gaps, faster problem resolution, and more practical recommendations. Instead of managing multiple vendors, organizations benefit from a partner that understands the complete system.

NETA testing refers to electrical testing performed in accordance with standards published by the International Electrical Testing Association (NETA). These standards establish testing procedures, acceptance criteria, and maintenance testing requirements for electrical power distribution equipment.

NETA testing is commonly performed during commissioning, maintenance outages, equipment evaluations, and reliability programs to verify equipment performance and identify developing problems before failures occur.

Arc flash studies are generally performed whenever significant changes occur within the electrical system. Common triggers include new equipment installations, protection system modifications, utility changes, facility expansions, and major modernization projects.

Many organizations also update arc flash studies periodically to ensure labels, incident energy calculations, and protection settings remain accurate.

Maintenance frequency depends on equipment age, operating conditions, criticality, environment, manufacturer recommendations, and maintenance history. Most facilities perform routine inspections annually, infrared scans on a regular basis, and comprehensive maintenance every three to five years.

Mission-critical facilities often perform maintenance more frequently based on reliability requirements.

A power system coordination study evaluates protective devices throughout an electrical system to ensure faults are isolated by the device closest to the problem. Proper coordination minimizes outage impact, improves reliability, protects equipment, and supports worker safety.

Coordination studies are commonly performed during new construction, expansions, modernization projects, and protection system upgrades.

Primary injection testing verifies the performance of the complete protection system by injecting actual current through current transformers, breakers, relays, and associated equipment. This approach validates overall system operation under realistic conditions.

Secondary injection testing focuses on relay performance by injecting signals directly into the relay without energizing primary equipment. It is commonly used to verify relay settings, logic functions, timing, and protective characteristics.
