Page 78 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 79 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 216  EVENTS: Disabled The B30 supports password entry from a local or remote connection. Local access is defined as access to settings or commands via the front panel. This includes both keypad entry and the RS232 port. Remote access is defined as access to settings or commands via any rear communications port. This includes both Ethernet and RS485 connections.
Page 217 When entering a settings or command password via EnerVista or any serial interface, the user must enter the corresponding connection password. If the connection is to the back of the B30, the remote password must be used. If the connection is to the RS232 port of the front panel, the local password must be used.

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 B30 responds to rising edges of the configured FlexLogic operands, they must be asserted for at least 50 ms to take effect.
Page 249 5.3.5.3 Ethernet network topology The B30 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.

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 B30. 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 317: 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 B30 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 318 See the Order Codes section in chapter 2 for details. The B30 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 319 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 B30 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 320 B30 clock is closely synchronized with the SNTP/ NTP server. It takes up to two minutes for the B30 to signal an SNTP self-test error if the server is offline.
Page 321  2:00 The B30 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 531 To provide the bus differential zoning as shown in the figures, eight currents need to be measured. Consequently, the protection cannot be accomplished by one B30. However, as each bus has not more than six connections, two B30s can be used.

Assuming 0.003 Ω/m lead resistance and approximating the B30 input resistance for the 5A input CTs as 0.2 VA / (5 A) 0.008 Ω, the limits of the linear operation of the CTs have been calculated and presented in the Limits of Linear Operations of the CTs table.

Page 542 The output logic (Block 11) combines the differential, directional, and saturation flags into the biased differential operation flag. The applied logic enhances performance of the relay while keeping an excellent balance between dependability/ speed and security. See the Output Logic and Examples section. B30 BUS DIFFERENTIAL SYSTEM – INSTRUCTION MANUAL...
Page 543: Dynamic Bus Replica
This mechanism is referred to as a dynamic bus replica. The dynamic bus zone is programmed as a number of ‘source-status’ pairs. The Sources feature of the B30 is a convenient and flexible mechanism for associating input currents and voltages with protection and control elements.
Page 544: Ct Ratio Matching
9.2.2 CT ratio matching The B30 allows for using CTs with various rated secondary currents and transformation ratios. Scaling to a common base is performed internally by the relay. The maximum allowable ratio mismatch is 32:1. For proper setting of the differential characteristic, it is imperative to understand the common base used by the relay.
Page 545: Differential Principle
Figure 9-3: Biased operating characteristic The higher slope used by the B30 acts as an actual percentage bias regardless of the value of the restraining signal. This is so because the boundary of the operating characteristic in the higher slope region is a straight line intersecting the origin of the ‘differential - restraining’...
Page 546: Differential And Restraining Currents
LOW BPNT 9.3.3 Enhanced security To enhance the performance of the B30, the differential characteristic is divided into two regions having diverse operating modes, as shown in following figure. The first region applies to comparatively low differential currents and has been introduced to deal with CT saturation on low-current external faults.
Page 547: Directional Principle
The B30 operates in the 2-out-of-2 mode in the first region of the differential characteristic. Both differential and directional principles (Differential Principle and Directional Principle) must confirm an internal fault in order for the biased differential element to operate.
Page 548 Figure 9-6: Directional principle operation during internal faults The B30 implementation calculates the maximum angle for the considered currents and compares it against a fixed threshold of 90°. The flag indicating whether the directional protection principle is satisfied is available as the FlexLogic...
Page 549: Saturation Detector
9.5.1 CT saturation detection The saturation detector of the B30 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 restraining signal develops rapidly.
Page 550: Output Logic And Examples
For high differential signals, the directional principle is included only if demanded by the saturation detector (dynamic 1- out-of-2 / 2-out-of-2 mode). Typically, the directional principle is slower, and by avoiding using it when possible, the B30 gains speed.
Page 551: Internal And External Fault Example
The first of the following figures presents the bus currents and the most important logic signals for the case of an external fault. Despite very fast and severe CT saturation, the B30 remains stable. The second figure presents the same signals but for the case of an internal fault. The B30 trips in 10 ms (fast form-C output contact).
