Main functions
Excitation system signal acquisition: In the UNITROL 1000/6000 excitation cabinets, it samples the generator rotor current and voltage, providing closed-loop regulation data.
Transmission system monitoring and protection: Provides high-precision current/voltage feedback for ACS800 and other medium/high-voltage inverters, achieving overcurrent, short circuit, and grounding fault protection.
Insulation and temperature monitoring: Integrates insulation resistance detection and PT100 temperature sampling, real-time monitoring of the insulation and temperature rise of high-voltage components.
