Page 15: Product Description
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 88 Eq. 3-2 The 2 mA current is used in case the contact input is connected across the GE Form A contact output with voltage monitoring. Otherwise use the amperage of the active circuit connected to the contact input when its contact output is open and the voltage across the contact input is third trigger threshold to calculate the resistor value.
Page 89 Contact inputs can be susceptible to parasitic capacitance, caused by long cable runs affected by switching surges from external circuits. This can result in inadvertent activation of contact inputs with the external contact open. In this case, GE recommends using the contact I/O module with active impedance circuit.

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.
Page 260 5.3.5.2 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 261 5.3.5.3 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.

Page 317 File transfer by IEC 61850 The T60 supports file transfer by IEC 61850. The approach is as follows, using the SISCO AX-S4 61850 client software as an example. In the AX-S4 61850 Explorer window, click the Tools menu and access the SISCO File Transfer Utility.
Page 318 NUMBER(80): 80 The T60 contains an embedded web server and can display pages in a web browser. The web pages are organized as a series of menus that can be accessed starting at the T60 “Main Menu.” Web pages are read-only and are available showing DNP and IEC 60870-5-104 points lists, Modbus registers, event records, fault reports, and so on.
Page 319 NUMBER: 0 The Trivial File Transfer Protocol (TFTP) can be used to transfer files from the T60 over a network. The T60 operates as a TFTP server. TFTP client software is available from various sources, including Microsoft Windows NT. The dir.txt file obtained from the T60 contains a list and description of all available files, for example event records and oscillography.
Page 320 COMMUNICATIONS  PROTOCOL connected to a maximum of two masters (usually either an RTU or a SCADA master station). Since the T60 maintains two sets of IEC 60870-5-104 data change buffers, ideally no more than two masters actively communicate with the T60 at one time.
Page 321 PRODUCT SETUP The T60 can specify a maximum of five clients for its IEC 104 connections. These are IP addresses for the controllers to which the T60 can connect. A maximum of two simultaneous connections are supported at any given time.
Page 322 EXCH 1 DATA ITEM 1 to 20/50 from the T60 memory map can be configured to be included in an EGD exchange. The settings are the starting Modbus register address for the data item in decimal format. See the Modbus memory map in the UR Series Communications Guide for details.
Page 323 PTP, or SNTP, its time is overwritten by these three sources, if any of them is active. If the synchronization timeout occurs and none of IRIG-B, PTP, or SNTP is active, the T60 sets the invalid bit in the time stamp of a time-tagged message.
Page 324 Spontaneous transmission occurs as a response to cyclic Class 2 requests. If the T60 wants to transmit Class 1 data at that time, it demands access for Class 1 data transmission (ACD=1 in the control field of the response).
Page 325 FlexAnalog operands. The measurands sent are voltage, current, power, power factor, and frequency. If any other FlexAnalog is chosen, the T60 sends 0 instead of its value. Note that the power is transmitted in KW, not W. Measurands are transmitted as ASDU 3 or ASDU 9 (type identification value set to measurands I, respectively measurands II).

CHAPTER 5: SETTINGS PRODUCT SETUP A list of available mappings is provided on the T60. This includes 64 virtual inputs (see the following table). The ON and OFF for the same ASDU command can be mapped to different virtual inputs.
Page 328: Real-Time Clock
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 329 See the Order Codes section in chapter 2 for details. 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 330 When a clock on start-up discovers that it is “better” than the present grandmaster, it assumes the grandmaster role and the previous grandmaster reverts to slave. The T60 qualification mechanism accepts a potential master clock as a new grandmaster, when in a four-second interval it has received three announce messages from it, all better than the present grandmaster clock and better than any other announce in this interval.
Page 331 T60 clock is closely synchronized with the SNTP/ NTP server. It takes up to two minutes for the T60 to signal an SNTP self-test error if the server is offline.
Page 332: User-Programmable Fault Report
 2:00 The T60 maintains two times: local time and Universal Coordinated Time (UTC). Local time can be provided by IRIG-B signals. UTC time is provided by SNTP servers. The real-time clock (RTC) and time stamps reported in historical records and communication protocols can be incorrect if the Local Time settings are not configured properly.

Page 371 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 372 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 373 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 374 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.
