Condition assessment of medium voltage (MV) circuit breakers is essential for ensuring the reliability and safety of electrical distribution systems. As these breakers age, their performance can degrade, leading to increased risks of failure. Advanced diagnostic techniques beyond basic inspections are crucial for accurately identifying wear or degradation.
Medium voltage circuit breakers, while robust, experience wear and degradation over time. Proactive condition assessment is key to preventing unexpected failures and optimizing their service life. Going beyond basic visual inspections with specialized techniques allows operators to make data-informed decisions concerning maintenance or replacements.
