The Reyrolle 7SR242 is a protection, control and monitoring relay for two winding transformers across all vector groups, primary configurations and earthing connections.
Transformers are vulnerable to faults and operational disruptions. The Reyrolle 7SR242 provides comprehensive protection, control and monitoring to safeguard your operations. It delivers critical insights into transformer status to prevent costly downtime.
Integrated logic allows optimal configuration of relay functionality, efficient setup and adaptable operation. Access protection, control, instrumentation and metering functions via data communication channels for remote monitoring. Use fault, event and waveform records for quick diagnosis and informed decision-making.
Deploy the 7SR242 across all transformer vector groups and primary configurations. Simplify your system design for consistent, reliable protection for your electrical infrastructure.
Use integrated logic to customize relay operations to improve resource allocation and enhance system responsiveness. Enjoy tailored control for better operational outcomes.
Monitor and manage your system from any location with flexible access options. Use a front USB port for local connections or a rear RS485 port for remote access. Stay informed and in control to make timely operational decisions.
Monitoring functions include primary/secondary currents phases and earth direction, relay and restraint currents, positive phase sequence (PPS) current, negative phase sequence (NPS) current and zero phase sequence (ZPS) current.
Configure relay functionality using integrated logic. Combine analogue inputs with binary input/output circuits for tailored performance. Adapt to your specific operational requirements.
Access protection, control, instrumentation and metering via data channels. Connect locally with a front USB port or remotely using a rear RS485 port. Integrate systems flexibly with additional rear port options.
