Page 83 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 84 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.

Page 314 NUMBER: 0 The Trivial File Transfer Protocol (TFTP) can be used to transfer files from the G30 over a network. The G30 operates as a TFTP server. TFTP client software is available from various sources, including Microsoft Windows NT. The dir.txt file obtained from the G30 contains a list and description of all available files, for example event records and oscillography.
Page 315 COMMUNICATIONS  PROTOCOL connected to a maximum of two masters (usually either an RTU or a SCADA master station). Since the G30 maintains two sets of IEC 60870-5-104 data change buffers, ideally no more than two masters actively communicate with the G30 at one time.
Page 316 CHAPTER 5: SETTINGS The G30 can specify a maximum of five clients for its IEC 104 connections. These are IP addresses for the controllers to which the G30 can connect. A maximum of two simultaneous connections are supported at any given time.
Page 317 EXCH 1 DATA ITEM 1 to 20/50 from the G30 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 318 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 G30 sets the invalid bit in the time stamp of a time-tagged message.
Page 319 Spontaneous transmission occurs as a response to cyclic Class 2 requests. If the G30 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 320 FlexAnalog operands. The measurands sent are voltage, current, power, power factor, and frequency. If any other FlexAnalog is chosen, the G30 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).

PRODUCT SETUP CHAPTER 5: SETTINGS A list of available mappings is provided on the G30. 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 323: 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 G30 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 324 See the Order Codes section in chapter 2 for details. The G30 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 325 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 G30 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 326 G30 clock is closely synchronized with the SNTP/ NTP server. It takes up to two minutes for the G30 to signal an SNTP self-test error if the server is offline.
Page 327: User-Programmable Fault Report
 2:00 The G30 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.

This standard states that the phase relationships are established for a condition where a source phase sequence of I-II-III is connected to transformer windings labeled I, II, and III respectively. 5-150 G30 GENERATOR PROTECTION SYSTEM – INSTRUCTION MANUAL...
Page 365 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 366 Interposing CTs or tapped relay windings were used to minimize this error. The G30 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 367 In this example, the unit CT is 1500:5 on winding 2. Magnitude compensation factors (M) are the scaling values by which each winding current is multiplied to refer it to the reference winding. The G30 calculates magnitude compensation factors for each winding as follows: Eq. 5-11 In our example, the magnitude compensation factors are calculated as follows: Eq.
Page 368 The G30 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 603: Theory Of Operation
10.1 Directional principle 10.1.1 Current directional protection For better security, the G30 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 604: Saturation Detector
