Continuous ripple current monitoring watches the battery string and DC bus for AC components that overheat plates, accelerate corrosion/dry-out, and trigger nuisance trips. By tracking ripple current and voltage wide-band sensors and built-in FFT, it isolates signatures from rectifier capacitor aging, diode/SCR imbalance, grounding issues, or harmonic back-feeds you fix causes, not symptoms. Smart thresholds and trending align with utility practice and standards, turning rising ripple into clear alarms and work orders instead of surprise DC failures. Non-intrusive, clamp-on installation makes retrofit fast during normal operation. SCADA/CMMS integration gives you dashboards, reports, and evidence of improvement. Result: healthier batteries, longer life, and rock-solid trip and control power when you need it most.
