KEY BENEFITS
>Secure high-speed protection for transformers, compliant with IEEE® C37.91
>Improved security for transformer energization and inrush provided through a superior adaptive 2nd harmonic restraint algorithm
>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
>Three independent fiber or copper Ethernet ports for simultaneous/dedicated network connections with advanced 1 microsecond time synchronization via LAN with IEEE 1588 support
>Reduced relay-to-relay wiring and associated installation costs through high-speed inter-relay communications
>Increase network availability by reducing failover time to zero through IEC 62439-3 “PRP” support
>CyberSentry? provides high-end cyber security aligned to industry standards and services (NERC® CIP, AAA, Radius, RBAC, Syslog)
>Advanced fault and disturbance recording, including internal relay operating signals, eliminating the need for redundant recording devices
>Integrated transformer thermal monitoring for asset management and maintenance optimization
>Complete IEC 61850 Process Bus solution provides resource optimization and minimizes total P&C life cycle costs
APPLICATIONS
>Transformer asset monitoring using hottest spot, loss-of-life and aging factor
>Applicable for transformers with up to six windings in a ring bus or breaker-and-a-half configuration
>Reliable and secure protection for three-phase transformers, autotransformers, reactors, split phase and phase angle regulating transformers
>Stand-alone or component in automated substation control system
