Generator protection

Protect generators and power plant units with the modular SIPROTEC 7UM85. It integrates all main protection functions, SIL2-certified reverse protection, and ATEX certification for explosive environments.

The SIPROTEC 7SX85 modular universal relay handles all protection, control, and automation tasks for 3-pole tripping. Its extensive function library ensures you pay only for the functions you apply.

Configure Reyrolle 7PG11 electro-mechanical relays for your exact auxiliary and tripping needs. Specify coils, flags, reset modes, and up to 8 normally open or closed contacts for precise scheme logic.

Ensure rapid system protection with the Reyrolle 7PG15. This robust relay offers <10ms operation, up to 20 contacts, high/low burden models, and complies with IEC 255-5 & BS142 standards for reliable, high-speed performance.

Get simple, robust protection for overhead lines and cables with the Reyrolle 7PG21. This three-phase differential unit detects in-zone phase and earth faults, ensuring straightforward installation and maintenance.

The Reyrolle 7PG17 is a versatile electro-mechanical relay for control, supply supervision, and trip circuit supervision. It ensures reliable remote switchgear operation by resisting induced AC voltage on pilot wires.

The Reyrolle 7PJ13 electronic relay ensures trip circuit integrity in LV/MV networks. It continuously supervises the trip coil and wiring, detecting faults like voltage loss or open circuits to generate a critical failure alarm.

The Reyrolle 7PG23 electro-mechanical relay detects earth faults in high impedance schemes. It provides restricted earth fault protection with a user-selectable voltage setting and integral over-voltage limiting.

The Reyrolle 7PJ15 is a high-speed, multi-contact trip relay for power stations and industrial applications. Designed to IEC 60255, it provides high burden, positive action, and instantaneous cutoff.

Reyrolle 7XG22 test blocks offer versatile CT shorting solutions with 8-14 way configurations for horizontal and vertical mounting applications.
