Description

The T60 is designed for various power applications, including autotransformers, generator step-up transformers, split-phase, angle regulating transformers and reactors. It uses multiple current and voltage inputs to provide primary protection and backup protection of transformers, including differential, ground differential, five distance zones, phase, neutral, and ground overcurrent, under and overvoltage, under and overfrequency, over-fluxing, and breaker failure. Key Benefits • Secure high-speed protection for transformers, compliant with IEEE C37.91 • 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 • Improved security for transformer energization and inrush provided through a superior adaptive 2nd harmonic restraint algorithm • Three independent fiber or copper Ethernet ports for simultaneous/dedicated network connections with advanced 1 microsecond time synchronization via LAN with IEEE 1588 support • Sensitive ground fault protection provides low- impedance differential protection down to 5% of the winding to limit transformer damage • Phasor Measurement Unit (synchrophasor) according to IEEE C37.118 (2011) and IEC 61850-90-5 support • CyberSentry™ provides high-end cyber security aligned to industry standards and services (NERC CIP, AAA, Radius, RBAC, Syslog)
