Page 69 This operation of contact inputs also can be prevented by using the Auto-Burnish contact inputs or contact inputs with active impedance.

Page 70 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 71 Consequently, the threshold voltage setting is also defined per group of two contact inputs. The auto-burnish feature can be disabled or enabled using the DIP switches found on each daughter card. There is a DIP switch for each contact, for a total of 16 inputs.

Page 77 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 T35 COM terminal (#3); others function correctly only if the common wire is connected to the T35 COM terminal, but insulated from the shield.
Page 78: 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 T35 operates an internal oscillator with 1 µs resolution and accuracy.

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 T35 responds to rising edges of the configured FlexLogic operands, they must be asserted for at least 50 ms to take effect.
Page 243 5.3.5.3 Ethernet network topology The T35 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 301 NUMBER(80): 80 The T35 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 T35 “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 302 NUMBER: 0 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, for example event records and oscillography.
Page 303 COMMUNICATIONS  PROTOCOL connected to a maximum of two masters (usually either an RTU or a SCADA master station). Since the T35 maintains two sets of IEC 60870-5-104 data change buffers, ideally no more than two masters actively communicate with the T35 at one time.
Page 304 0.0.0.0 The T35 can specify a maximum of five clients for its IEC 104 connections. These are IP addresses for the controllers to which the T35 can connect. A maximum of two simultaneous connections are supported at any given time.

Commands are received as General Command (Type Identification 20). The user can configure the action to perform when an ASDU command comes. A list of available mappings is provided on the T35. 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 311: 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 T35 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 312 See the Order Codes section in chapter 2 for details. The T35 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 313 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 T35 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 314 T35 clock is closely synchronized with the SNTP/ NTP server. It takes up to two minutes for the T35 to signal an SNTP self-test error if the server is offline.
Page 315: User-Programmable Fault Report
 2:00 The T35 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.

Page 353 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 354 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 355 Interposing CTs or tapped relay windings were used to minimize this error. 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.
Page 356 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.

Page 531: Theory Of Operation
9.1 Directional principle 9.1.1 Current directional protection For better security, the T35 uses the current directional protection principle to dynamically supervise the main current differential function. The directional principle is in effect permanently for low differential currents (region 1 in the Two Regions of Differential Characteristic figure) and is switched on dynamically for large differential currents (region 2 in the same figure) by the saturation detector (see the Saturation Detector section) upon detecting CT saturation.
Page 532: Saturation Detector
9.2.1 CT saturation detection The saturation detector of the T35 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 T35 TRANSFORMER PROTECTION SYSTEM –...
