CANA High Voltage has a trained workforce that performs full commissioning and testing services on our projects to ensure they meet the stringent standards put forth for safety and performance.

We Utilize Certified Procedures for All Substation Components

CANA High Voltage employees qualified, skilled and knowledgeable personnel who understand the importance of accurate and detailed commissioning and testing. Our staff have the knowledge and training on how to test and commission complete substations, including Power Transformers, Current Transformers, Potential Transformers and Circuit Breakers and control schemes in voltage ranging between 4.16 kV to 500 kV.

All procedures meet the InterNational Electrical Testing Association (NETA) standards. By meeting NETA standards, CANA High Voltage confirms our commitment to meeting stringent educational and experience requirements and understanding the broad-based knowledge that is required to test and commission high voltage facilities.

We providing the following testing and commissioning services to confirm performance compliance and safety prior to energization.
