Page 82: Introduction To Ac Sources
BACKGROUND The T60 may be used on systems with breaker-and-a-half or ring bus configurations. In these applications, each of the two three-phase sets of individual phase currents (one associated with each breaker) can be used as an input to a breaker fail- ure element.
Page 83 The CT/VT modules calculate total waveform RMS levels, fundamental frequency phasors, symmetrical components and harmonics for voltage or current, as allowed by the hardware in each channel. These modules may calculate other parameters as directed by the CPU module. GE Multilin T60 Transformer Management Relay...
Page 84 Source is a transformer winding, on which a three phase voltage is mea- sured, and the sum of the currents from CTs on each of two breakers is required to measure the winding current flow. T60 Transformer Management Relay GE Multilin...
Page 85: Product Setup
If an entered password is lost (or forgotten), consult the factory with the corresponding ENCRYPTED PASSWORD The T60 provides a means to raise an alarm upon failed password entry. Should password verification fail while accessing a password-protected level of the relay (either settings or commands), the UNAUTHORIZED ACCESS FlexLogic™ oper- and is asserted.
Page 86: Display Properties
Some customers prefer very low currents to display as zero, while others prefer the current be displayed 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 87: Clear Relay Records
MESSAG Valid only for units with Direct I/O module. The T60 allows selected records to be cleared from user-programmable conditions with FlexLogic™ operands. Setting user-programmable pushbuttons to clear specific records are typical applications for these commands. The T60 responds to rising edges of the configured FlexLogic™ operands. As such, the operand must be asserted for at least 50 ms to take effect.
Page 88: Communications
0 ms The T60 is equipped with up to 3 independent serial communication ports. The faceplate RS232 port is intended for local use and is fixed at 19200 baud and no parity. The rear COM1 port type will depend on the CPU ordered: it may be either an Ethernet or an RS485 port.
Page 89 MODBUS SLAVE ADDRESS grammed. For the RS485 ports each T60 must have a unique address from 1 to 254. Address 0 is the broadcast address which all Modbus slave devices listen to. Addresses do not have to be sequential, but no two devices can have the same address or conflicts resulting in errors will occur.

Page 91 DNP VOLTAGE SCALE FACTOR Input points that are voltages will be returned with values 1000 times smaller (e.g. a value of 72000 V on the T60 will be returned as 72). These settings are useful when Analog Input values must be adjusted to fit within certain ranges in DNP masters.
Page 92 NUMBER: The Trivial File Transfer Protocol (TFTP) can be used to transfer files from the UR 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 (event records, oscillography, etc.).
Page 93 THRESHOLD: 30000 The T60 supports the IEC 60870-5-104 protocol. The T60 can be used as an IEC 60870-5-104 slave device connected to a single master (usually either an RTU or a SCADA master station). Since the T60 maintains one set of IEC 60870-5-104 data change buffers, only one master should actively communicate with the T60 at one time.
Page 94: Modbus User Map
T60 clock is closely synchronized with the SNTP/NTP server. It may take up to one minute for the T60 to signal an SNTP self-test error if the server is offline.
Page 95: User-Programmable Fault Report
The user programmable record contains the following information: the user-programmed relay name, detailed firmware revision (3.4x, for example) and relay model (T60), the date and time of trigger, the name of pre-fault trigger (specific Flex- Logic™ operand), the name of fault trigger (specific FlexLogic™ operand), the active setting group at pre-fault trigger, the active setting group at fault trigger, pre-fault values of all programmed analog channels (one cycle before pre-fault trigger), and fault values of all programmed analog channels (at the fault trigger).

Page 122 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 123 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.

Deadbands for individual Analog Input Points can be set using DNP Object 34. When using the T60 in DNP systems with limited memory, the Analog Input Points below may be replaced with a user- definable list. This user-definable list uses the same settings as the Modbus User Map and can be configured with the Mod- bus User Map settings.
