The SIPROTEC 7VK61 is a flexible breaker management device. It provides autoreclosure, synchro-check and circuit breaker failure protection. Use this unit for single and three-pole auto-reclosure of a circuit breaker after a fault trip.
Circuit breakers can fail to open and clear faults, requiring you to trip entire busbar zones. The SIPROTEC 7VK61 solves this by offering robust circuit breaker failure protection. It also ensures safe reconnection of circuits with its synchro-check function, verifying a safe operating state before closing the breaker.
Benefit from flexible operation as all functions can be used separately. The highly secure 2-out-of-4 current check detectors in the breaker failure protection enhance system reliability. Additionally, integrated control and monitoring functions support cost-effective power system management.
Enhance overall system reliability by quickly clearing faults with auto-reclosure and preventing breaker failures. Minimize downtime and maintain continuous power supply for critical operations. Ensure stable grid performance.
Support cost-effective power system management with integrated control and monitoring functions. Streamline operations and reduce manual intervention for improved efficiency. Gain comprehensive insights into system performance.
Safeguard your electrical assets with comprehensive protection functions: end-fault, pole-discrepancy, overvoltage and undervoltage protection. Protect equipment from damage, ensure personnel safety and maintain secure operations.
Perform single and three-pole auto-reclosure of a circuit-breaker after a fault trip. This unit supports up to 8 reclose cycles with ADT, DLC and RDT for efficient fault clearance. Quickly restore power system stability.
Verify two circuits are in a defined safe operating state before issuing a CLOSE command. This function includes live/dead line/bus measurement and ΔV, Δφ, Δf measurement for precise control. Achieve secure system reconnection.
Apply two-stage circuit-breaker failure protection for single and three-pole trips. Clear faults by tripping the relevant busbar zone if the circuit-breaker fails to open. Utilize highly secure 2-out-of-4 current check detectors.
