How often should infrared testing be conducted in substations?

• A. Monthly
• B. Annually or biannually, depending on the equipment and conditions
• C. Every five years
• D. Only after equipment has been replaced

Answer: (B)

Infrared testing, or thermography, is a critical component of substation maintenance as it identifies hot spots and potential failure points in electrical equipment. Conducting infrared testing annually or biannually, depending on specific equipment and environmental conditions, helps in proactively managing equipment health and avoiding unexpected failures. The frequency of testing is influenced by various factors such as the age of the equipment, its operational conditions, and past performance. For example, older equipment or equipment that has previously shown signs of thermal issues may require more frequent testing. Conversely, newly installed or well-maintained equipment might not need as frequent assessments. Performing these tests regularly allows for timely detection of issues before they develop into more significant problems, ultimately leading to increased reliability and reduced downtime in substations. Regular infrared testing aligns with best practices in predictive maintenance, ensuring that the equipment operates efficiently and safely. By responding to findings from these tests, maintenance teams can prioritize repairs and replacements based on the severity of the issues detected, which further enhances operational reliability.
