Gate Pulse Amplifier GE IS200EHPAG1BBA for Excitation and Protection Systems

Description

TheGE IS200EHPAG1BBAis ahigh-reliability exciter gate pulse amplifierdesigned forGE’s EX2100 excitation control platform. It amplifiesgate pulse signalsfrom theESEL logic boardand drivessix silicon-controlled rectifiers (SCRs)in thepower bridge. These SCRs regulate the generator’sfield current, ensuringstable voltage outputandsafe operationunder dynamic load conditions. Additionally, the board includes several monitoring features such asconduction current feedback,airflow, andtemperature sensing. These features help prevent issues likemisfires,overheating, andelectrical faults, contributing tosystem safetyandoperational continuity. Itscompact, rack-mounted designallows foreasy integrationintoexcitation cabinets, making it suitable for bothnew installationsandretrofit projects. This board is widely used insteam,gas, andhydroelectric power plants, where preciseSCR controlis crucial forgenerator protectionandperformance.
