T35 Transformer Protection System

Product Description

T35 Transformer Protection System

The T35 is designed to provide basic transformer protectionfunctions for variety of transformer applications. It uses multiple currentinputs to provide primary protection and backup protection of transformers,including differential, phase and ground overcurrent. The relay can be configuredto accept up to 6 sets of current inputs to provide proper differentialrestraint for applications with three-winding transformers with windingsconfigured in dual-breaker arrangements.

Key Benefits

• Secure high-speed transformer differential protection in a cost-effective package
• Improved security for transformer energization and inrush
• Application flexibility for transformers with up to 6 sets of CTs
• Robust network security enabling Critical Infrastructure Protection
• Advanced IEC 61850 Ed. 1 and Ed. 2 certified implementation, complete settings via SCL files and flexible process bus support (IEC 61850-9-2LE or IEC 61850-9-2 Hardfiber) ensures interoperability, device managing optimization and reduced cost of ownership
• Routable GOOSE (R-GOOSE) enables GOOSE messages going beyond the substation, which enables wide area protection and control applications
• High-speed inter-relay communications reduce relay-to-relay wiring and associated costs
