Basler 9 2007 00 100 Current Boost System CBS 305

The Basler 9 2007 00 100, also known as the CBS 305 Current Boost System, is a specialized excitation support device designed for synchronous generators. This system provides additional boosting current to the generator field during severe fault conditions or voltage dips, helping to maintain system voltage stability and prevent generator tripping. The CBS 305 is typically used in utility and industrial power systems where grid disturbances can cause significant voltage drops.

The current boost system operates by sensing the generator voltage and current, and upon detecting a fault condition, injects a controlled boost into the excitation circuit. It features a rugged construction with high‑quality components, designed for reliable operation in demanding environments. The CBS 305 includes adjustable settings for boost level and duration, allowing customization to match specific generator and system requirements.
