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.

ANSI Device Numbers & Functions

Key Features

• Metering - current, voltage, power, energy, frequency, temperature, transformer monitoring
• P & M class synchrophasors of voltage, current and sequence components – 1 to 120 frames/sec
• Oscillography – analog and digital parameters at 64 samples/cycle
• Event Recorder - 1024 time tagged events with 0.5ms scan of digital inputs
• Data Logger - 16 channels with sampling rate up to 1 sample / cycle
• Setting for security audit trails for tracking changes to T60 configurations

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

• Three independent 100Mbps Ethernet ports enable purpose specific LAN support that eliminates latency effect of heavy traffic protocols on mission critical communication services
• Embedded IEEE 1588 time-synch protocol support eliminates dedicated IRIG-B wiring requirements for IEDs
• Direct I/O secures high-speed exchange of binary data between URs
• Increase network availability by reducing failover time to zero through IEC62439-3 PRP, HSR or dual HSR support

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. 
The T60 supports the most popular industry standard protocols enabling easy, direct integration into DCS and SCADA systems.

Interoperability with Embedded IEC 61850

Use the T60 with integrated IEC 61850 to lower costs associated with power transformer, control and automation. GE Vernova’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. Learn more

The T60 can also connect to GE Vernova MU320 or third-party merging units using standard IEC 61869 or IEC 61850-9-2LE communication protocols.

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.

The iSTAT M365 utilizes QDSP setup software to allow for easy initial meter setup, configuration and data visualization.

The iSTAT M365 support multiple types of time synchronization to ensure accuracy and synchronization of various measurements and events to meet standards.

GE Vernova Reason RT43x GNSS clocks are recommended to provide accurate time synchronization.

• Unmodulated (DC 5V level shift) and modulated (1 kHz) serial coded format with support for 1pps, day of year, current year and straight seconds of day as described in standard IRIG-200-04. GE Vernova Reason RT43x GNSS clocks recommended for time synchronization
• Supported serial time code formats are IRIG-B007 and IRIG-B127 Interface for modulated IRIG-B is designed as BNC-F terminal with 600 Ohm input impedance
• Interface for unmodulated IRIG-B is designed as pluggable terminal

• Synchronization via Ethernet requires access to a NTP server

Note: NTP can usually maintain time to within tens of milliseconds over the public Internet, but the accuracy depends on infrastructure properties - asymmetry in outgoing and incoming communication delay affects systematic bias. It is recommended that dedicated network rather than public network is used for Synchronization purposes.

The iSTAT M365 supports various communications connections and protocols for easy integration. It is equipped with standard communication port COM1 (Ethernet & USB) and an auxiliary communication port COM2 (RS232/RS485).

Refurbishment Solutions – “If It’s Blue Think to Renew”

GE Vernova’s latest MiCOM P140 series models P141 to P145 inclusive offer an ideal path to refurbish an older installed base of MiCOM P140 relays. Whether those older products were initially sold as GE VERNOVA or AREVA-branded products, newer models retain pin-pin refurbishment capability. Advantageously, users can benefit from the advancements made in protection, control, communications, hardware and cybersecurity that have taken place in the intervening years. The new P40 retains form, fit and function compatibility but delivers the latest platform and software ready for today’s environment, and for future-proofed application for the decades ahead.

Pin-Pin Upgrade Methodology:

• Take the order code (CORTEC) of the older relay being removed, typically a blue case relay
• Translate to today’s latest GE Vernova MiCOM model, adding Ethernet options if required
• Order the new P40 relay
• Extract settings and logic, use S1 Agile toolsuite to convert settings
• Detach the terminal blocks from old relay, leaving wiring attached / detach terminal blocks from the new.
• Carefully examine the terminal blocks to see that no physical damage has occurred since installation
• Mount new relay. Old relay blocks fit straight onto the new relay - safer, less wiring to reconnect.
• It is recommended to apply rated current and voltage to the relay CT/VT inputs during secondary injection testing to check the continuity of the CT/VT terminal block connections to the relay.
• Download converted files
• Test, return circuit to service with only minutes of downtime
