ABB SPAU140C Synchro-Check Relay In Stock 100% Genuine with Factory Sealed

Product Description

The numerical synchro-check relay type SPAU 140 C is a voltage measuring relay designed to be used when two power systems are to be connected together.

The synchro-check relay SPAU 140 C can be used for both synchro-check functions and voltage-check functions. The synchro-check function is used when two separate networks or two electrically interconnected network sections are to be connected together. The voltage-check function is used when a disconnected bus/line is to be connected to an energized section of a network. The synchro-check function allows circuit breaker closing only if the voltages on both sides of the circuit breaker fulfill the preset conditions as to magnitude, phase and frequency difference.

ABB SPAU140C Synchro-Check Relay (Possible Function)

• Synchronization Verification: Monitors various parameters like voltage, frequency, phase angle, and phase sequence to verify conditions are suitable for safe synchronization.
  
• Synchronization Control (possible): In some models, the relay might provide control outputs to adjust generator speed or voltage regulator setpoints to facilitate synchronization.
  
• Protection against Mismatched Conditions: Helps prevent damage to equipment by tripping circuit breakers or issuing warnings if synchronization parameters fall outside safe limits.
  
• Configurable Settings: Allows customization of voltage, frequency, and phase angle tolerances for synchronization based on system requirements (check manuals).
