Real-time diagnostic tools, such as contact resistance and partial discharge testing, are essential for effective predictive maintenance. This method allows for the early identification of issues, helping to prolong the life of electrical devices and ensure a reliable power supply. By implementing predictive maintenance strategies, companies can enhance the performance of their switchgear and avoid unexpected system failures.
Partial discharge testing is needed since it detects an initial sign of degradation in insulation before full failure. It is vital to detect earlier so that it may ensure the integrity of the insulation, increase the reliability of switchgear, and minimize the chances of catastrophic electrical failure and expenditures.
In the interest of safety and reliability, switchgear and circuit breaker testing is done as per internationally developed standards like IEC 62271, IEEE C37, and NEMA SG5. These standards specify elaborate test procedures, like measurement of insulation and contact resistance, timing analysis, and partial discharge monitoring, to conform to standards.
