Page 82: Introduction To Ac Sources
BACKGROUND The T35 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 T35 Transformer Management Relay...

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 T35 applies a cut- off value to the magnitudes and angles of the measured currents.
Page 87 VOLTAGE CUT-OFF LEVEL CURRENT CUT-OFF LEVEL as valid measurements. Unless dictated otherwise by a specific application, the default settings of “0.02 pu” for and “1.0 V” for are recommended. NOTE CURRENT CUT-OFF LEVEL VOLTAGE CUT-OFF LEVEL GE Multilin T35 Transformer Management Relay...
Page 88: Clear Relay Records
Selected records can be cleared from user-programmable conditions with FlexLogic™ operands. Assigning user-program- mable pushbuttons to clear specific records are typical applications for these commands. Since the T35 responds to rising edges of the configured FlexLogic™ operands, they must be asserted for at least 50 ms to take effect.
Page 89: Communications
0 ms The T35 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 is selected when ordering: either an Ethernet or RS485 port.
Page 90 MODBUS SLAVE ADDRESS grammed. For the RS485 ports each T35 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 92 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 T35 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 93 47, etc. The minimum number of binary input points that can be selected is 16 (1 block). If all of the BIN INPUT BLOCK X settings are set to “Not Used”, the standard list of 928 points will be in effect. The T35 will form the binary inputs points list from the settings up to the first occurrence of a setting value of “Not Used”.
Page 94 The T35 supports the Manufacturing Message Specification (MMS) protocol as specified by IEC 61850. MMS is supported over two protocol stacks: TCP/IP over ethernet and TP4/CLNP (OSI) over ethernet. The T35 operates as an IEC 61850 server. The Remote Inputs/Outputs section in this chapter describe the peer-to-peer GSSE/GOOSE message scheme.
Page 95 Internet Explorer or Netscape Navigator. This feature is available only if the T35 has the ethernet option installed. The web pages are organized as a series of menus that can be accessed starting at the T35 “Main Menu”. Web pages are available showing DNP and IEC 60870-5-104 points lists, Modbus registers, Event Records, Fault Reports, etc.
Page 96 NUMBER: The Trivial File Transfer Protocol (TFTP) can be used to transfer files from the T35 over a network. The T35 operates as a TFTP server. TFTP client software is available from various sources, including Microsoft Windows NT. The dir.txt file obtained from the T35 contains a list and description of all available files (event records, oscillography, etc.).
Page 97 T35 clock is closely synchronized with the SNTP/NTP server. It may take up to one minute for the T35 to signal an SNTP self-test error if the server is offline.
Page 98 MESSAGE (Modbus register address range) Fast exchanges (50 to 1000 ms) are generally used in control schemes. The T35 has one fast exchange (Exchange 1) and two slow exchanges (Exchanges 2 and 3). The settings menu for the slow EGD exchanges is shown below: !"...

Page 125 CTs and tapped relay windings with some combination of CT connections. The T35 simplifies these configuration issues. All CTs at the transformer are connected Wye (polarity markings pointing away from the transformer). User-entered settings in the relay characterizing the transformer being protected and allow the relay to automatically perform all necessary magnitude, phase angle, and zero sequence compensation.
Page 126 The reason the source phase sequence must be stated when describing the winding phase relationships is that these rela- tionships change when the phase sequence changes. The example shown below shows why this happens, using a trans- former described in IEC nomenclature as a type “Yd1” or in GE Multilin nomenclature as a “Y/d30.” 828716A1.CDR Figure 5–14: EXAMPLE TRANSFORMER...
Page 127 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) 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 128 5.3 SYSTEM SETUP 5 SETTINGS The T35 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. The reference winding (w ) is the winding to which all currents are referred.
Page 129 The T35 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.

The T35 relay supports IEC 61850 server services over both TCP/IP and TP4/CLNP (OSI) communication protocol stacks. The TP4/CLNP profile requires the T35 to have a network address or Network Service Access Point (NSAP) to establish a communication link. The TCP/IP profile requires the T35 to have an IP address to establish communications. These addresses are located in the !"...

Events Since Last Clear A counter freeze command has no meaning for counters 8 and 9. T35 Digital Counter values are represented as 32-bit inte- gers. The DNP 3.0 protocol defines counters to be unsigned integers. Care should be taken when interpreting negative counter values.
Page 329: Analog Inputs
Deadbands for individual Analog Input Points can be set using DNP Object 34. When using the T35 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.
