Page 15: Product
2.1 Product description The T60 Transformer Protection System is part of the Universal Relay (UR) series of products. It is a microprocessor-based relay for protection of small, medium, and large three-phase power transformers. The relay can be configured for a maximum of six three-phase current inputs and six ground current inputs, and can satisfy applications with transformer windings connected between two breakers, such as in a ring bus or in breaker-and-a-half configurations.
Page 16: Description
Secure Routable GOOSE (R-GOOSE) is supported with software options. Settings and actual values can be accessed from the front panel or EnerVista software. The T60 uses flash memory technology that allows field upgrading as new features are added. Firmware and software are upgradable.

Page 18: Security
The T60 supports password entry from a local or remote connection. Local access is defined as any access to settings or commands via the faceplate interface. This includes both keypad entry and the through the faceplate RS232 port. Remote access is defined as any access to settings or commands via any rear communications port.
Page 19 When entering a settings or command password via EnerVista or any serial interface, the user must enter the corresponding connection password. If the connection is to the back of the T60, the remote password must be used. If the connection is to the RS232 port of the faceplate, the local password applies.

Page 88 This common voltage is implied to be a power supply common. Some systems allow the shield (drain wire) to be used as common wire and to connect directly to the T60 COM terminal (#3); others function correctly only if the common wire is connected to the T60 COM terminal, but insulated from the shield.
Page 89: Irig-B
IRIG-B is a standard time code format that allows stamping of events to be synchronized among connected devices. The IRIG-B code allows time accuracies of up to 100 ns. Using the IRIG-B input, the T60 operates an internal oscillator with 1 µs resolution and accuracy.

Page 138: Settings File Traceability
When a settings file is transferred to a T60 device, the date, time, and serial number of the T60 are sent back to EnerVista UR Setup and added to the settings file on the local computer. This information can be compared with the T60 actual values at any later date to determine if security has been compromised.
Page 139 With respect to the figure, the traceability feature is used as follows. The transfer date of a settings file written to a T60 is logged in the relay and can be viewed in the EnerVista software or the front panel display. Likewise, the transfer date of a settings file saved to a local computer is logged in the EnerVista software.

Page 197 This feature requires a CyberSentry software option. See the Order Codes section in chapter 2 for details. The EnerVista software provides the means to configure and authenticate the T60 access using either a server or the device. Access to functions depends on user role.
Page 198 When the "Device" button is selected, the T60 uses its local authentication database and not the RADIUS server to authenticate the user. In this case, it uses built-in roles (Administrator, Engineer, Supervisor, Operator, Observer, or Administrator and Supervisor when Device Authentication is disabled), as login accounts and the associated passwords are stored on the T60 device.

Page 208 Some customers prefer very low currents to display as zero, while others prefer the current to display even when the value reflects noise rather than the actual signal. The T60 applies a cut-off value to the magnitudes and angles of the measured currents.
Page 209: Clear Relay Records
Selected records can be cleared from user-programmable conditions with FlexLogic operands. Assigning user- programmable pushbuttons to clear specific records is a typical application for these commands. Since the T60 responds to rising edges of the configured FlexLogic operands, they must be asserted for at least 50 ms to take effect.

5.3.4.2 Serial ports The T60 is equipped with up to two independent serial communication ports. The faceplate RS232 port is for local use and is fixed at 19200 baud and no parity. The rear COM2 port is used for either RS485 or RRTD communications.
Page 211 5.3.4.3 Ethernet network topology The T60 has three Ethernet ports. Each Ethernet port must belong to a different network or subnetwork. Configure the IP address and subnet to ensure that each port meets this requirement. Two subnets are different when the bitwise AND operation performed between their respective IP address and mask produces a different result.

The delay in switching back ensures that rebooted switching devices connected to the T60, which signal their ports as active prior to being completely functional, have time to completely initialize themselves and become active. Once port 2 is active again, port 3 returns to standby mode.

Page 277 Setup for IRIG-B is illustrated in the Installation chapter. For the Other protocols, whenever a time synchronization message is received through any of the active protocols, the T60 clock updates. However, given that IEC 60870-5-103, IEC 60870-5-104, Modbus, and DNP are low-accuracy time synchronization methods, avoid their use for synchronization when better accuracy time protocols, such as IRIG-B and PTP, are active in the system.
Page 278 PRODUCT SETUP CHAPTER 5: SETTINGS The T60 supports the Precision Time Protocol (PTP) specified in IEEE Std 1588 2008 using the Power Profile (PP) specified in IEEE Std C37.238 2011. This enables the relay to synchronize to the international time standard over an Ethernet network that implements PP.

Page 316  3φ: 10.0000 ohms The T60 is provided with this optional feature, specified as an option at the time of ordering. Using the order code for your device, see the order codes in chapter 2 for details. The settings specific to each winding are shown in the table.
Page 317 The following example shows why this happens, using a transformer described in IEC nomenclature as a type “Yd1” or in GE Multilin nomenclature as a “Y/d30.” The example shows the physical connections within the transformer that produce a phase angle in the delta winding that lag the respective wye winding by 30°.
Page 318 Note that the delta winding currents leads the wye winding currents by 30°, (which is a type Yd11 in IEC nomenclature and a type Y/d330 in GE Multilin nomenclature) and which is in disagreement with the transformer nameplate. This is because the physical connections and hence the equations used to calculate current for the delta winding have not changed.
Page 319 Interposing CTs or tapped relay windings were used to minimize this error. The T60 automatically corrects for CT mismatch errors. All currents are magnitude compensated to be in units of the CTs of one winding before the calculation of differential and restraint quantities.
Page 320 The T60 performs this phase angle compensation and zero sequence removal automatically, based on the settings entered for the transformer. All CTs are connected Wye (polarity markings pointing away from the transformer). All currents are phase and zero sequence compensated internally before the calculation of differential and restraint quantities.

Page 617: Ct Saturation Detection
9.1.1 CT saturation detection The saturation detector of the T60 takes advantage of the fact that any CT operates correctly for a short period of time, even under very large primary currents that would subsequently cause a very deep saturation. As a result, in the case of an external fault, the differential current stays very low during the initial period of linear operation of the CTs while the restraining signal develops rapidly.
