Key Benefits
Protection & Control The T60 transformer protection system is a comprehensive three-phase transformer relay designed to protect medium and large power transformers. The T60 provides automatic or user-definable magnitude reference winding selections for CT ratio matching, and performs automatic phase shift compensation for all types of transformer winding connections. The T60 algorithm allows the user to enable removal of the zero-sequence current even for delta-connected transformer windings, facilitating transformers with a variety of grounding configurations. As part of the Universal Relay (UR) Family, the T60 provides superior protection and control. Functional Block Diagram ANSI Device Numbers & Functions
Key Features
Monitoring & Diagnostic The T60 includes high accuracy metering and recording for all AC signals. Voltage, current, and power metering are built into the relay as a standard feature. Current and voltage parameters are available as total RMS magnitude, and as fundamental frequency magnitude and angle. For power quality applcations, harmonic measurements (up to the 25th) for voltage and current are available. T60 can monitor, calculate and log hottest-spot temperature, aging factor and loss-of-life data over a long period. This data, combined with economic analysis, allows criteria to be developed regarding the best time at which to replace a power transformer due to load growth, i.e. to minimize the cost without significantly increasing the risk. Advanced Automation The T60 incorporates advanced automation features including powerful FlexLogic™ programmable logic, communication, and SCADA capabilities that far surpass what is found in the average transformer relay. The T60 integrates seamlessly with other UR relays for complete system protection. Key Features Complete IEC 61850 Process Bus solution providing resource optimization and minimizing total P & C life cycle costs
Advanced Communications The T60 provides advanced communications technologies for remote data and engineering access, making it the most advanced and flexible transformer protection relay to use and integrate into new and existing infrastructures. Direct support for fiber optic Ethernet provides high-bandwidth communications allowing for low-latency controls and high-speed file transfers of relay fault and event record information. The available three independent and redundant Ethernet options provide the means to create fault tolerant communication architectures in an easy, cost-effective manner.
Interoperability with Embedded IEC 61850 Use the T60 with integrated IEC 61850 to lower costs associated with power transformer, control and automation. GE’s leadership in IEC 61850 comes from thousands of installed devices and follows on years of development experience with UCA 2.0. The T60’s IEC 61850 Process Bus module is designed to interface with the Multilin HardFiber System, allowing bi-directional IEC 61850 fiber optic communications. The HardFiber System is designed to integrate seamlessly with existing Universal Relay applications, including protection functions, FlexLogic, metering and communications.

Cyber Security - CyberSentry™ UR (FW v7.4xx) CyberSentry enables UR devices to deliver full cyber security features that help customers to comply with NERC CIP and NITIR 7628 cyber security requirements through supporting the following core features: Secure FW upgrade UR FW files v7.9 and up now include a hash code that allows for authentication prior to being used for upgrading UR devices. Password Complexity Supporting up to 20 alpha- numeric or special characters, UR passwords exceed NERC CIP requirements for password complexity. Individual passwords per role are available. AAA Server Support (Radius) Enables integration with centrally managed authentication and accounting of all user activities and uses modern industry best practices and standards that meet and exceed NERC CIP requirements for authentication and password management. Role Based Access Control (RBAC) Efficiently administrate users and roles within UR devices. The new and advanced access functions allow users to configure up to five roles for up to eight configurable users with independent passwords. The standard “Remote Authentication Dial In User Service” (Radius) is used for authentication. Event Recorder (Syslog for SEM) Capture all cyber security related events within a SOE element (login, logout, invalid password attempts, remote/local access, user in session, settings change, FW update, etc), and then serve and classify data by security level using standard Syslog data format. This enables UR devices integration with established SEM (Security Event Management) systems. EnerVista™ Software The EnerVista™ suite is an industry-leading set of software programs that simplifies every aspect of using the T60 relay. The EnerVista™ suite provides all the tools to monitor the status of the protected asset, maintain the relay, and integrate information measured by the T60 into DCS or SCADA monitoring systems. Convenient COMTRADE and Sequence of Events viewers are an integral part of the UR setup software included with every UR relay, to carry out postmortem event analysis and ensure proper protection system operation.
