Research and Application of Innovative Smart Sensors and AI-based Diagnostic, Prognostic and Prescription Software for Series Capacitors

Series Capacitor Banks (SCBs) are essential for the operation of long transmission lines (TL). Their unavailability, often triggered by failures in individual capacitor units, can cause operational restrictions, instability, and even line outages. Current monitoring practices rely on detecting current imbalance between SCB branches, which reveals problems only at advanced stages, after multiple capacitor units have already failed and lengthy shutdowns are required for troubleshooting and repair.
