High-speed, two to six windings transformer protection system. The T60, a member of the UR Family of protection relays, is a three-phase, multiple winding, transformer relay intended for the primary protection and management of small, medium and large power transformers. Includes a full featured set of protection, I/O, data logging, and communications capabilities.
Cost effective transformer protection for up to six windings. The T35, a member of the UR Family, is a digital three–phase transformer relay designed to protect any size of power transformer with up to six windings/restraints. The T35 has a more focused protection feature set than the T60, yet still has all the I/O, data logging, and communications options.
High-speed draw-out multiprocessor-based relay for transformer protection and management. The 745 Transformer Protection System, a member of the SR Family of protection relays, is a high-speed, multiprocessor-based, three-phase, two or three-winding transformer management relay intended for the primary protection and management of small, medium and large power transformers. In a draw case, it also includes analog inputs and outputs, while incorporating advanced features such as transformer loss of life monitoring.
Microprocessor-based system for primary and backup protection of small and medium sized, 2-winding, distribution transformers. The Multilin 345 offers advanced algorithms for magnitude and phase compensation. The 345 includes advanced communications supporting simultaneous communications, enhanced draw-out construction and enhanced diagnostics for asset monitoring and simplified setup & configuration tools to reduce commissioning time.
The DTP-B is a digital relay that provides high-speed differential and backup instantaneous differential three phase protection functions for power transformers. Different models of the DTP are available for protecting and monitoring transformers with two, three or four windings.
