As such, no further functional tests are required. The B90 performs a number of continual self-tests and takes the necessary action in case of any major errors (see the Relay Self-tests section in chapter 7). However, it is recommended that B90 maintenance be scheduled with other system maintenance.
Page 31: Product Description
The B90 Low Impedance Bus Differential System is a microprocessor-based architecture that provides protection and metering for busbars with up to 24 feeders. The B90 protection system is a centralized architecture built on one B90 IED as per requirements of a particular application. The IED is a full-featured B90 and as such can be accessed and programmed individually.

1 to 50000 A primaries and 1 A or 5 A secondaries may be used. Each B90 voltage input is intended for monitoring a single-phase voltage. The may include phase voltages or neutral volt- age from the open-delta VT.
Page 62: Contact Inputs And Outputs
The terminal configuration for contact inputs is different for the two applications. The contact inputs are grouped with a common return. The B90 has two versions of grouping: four inputs per common return and two inputs per common return. When a contact input/output module is ordered, four inputs per common is used.
Page 63 Logic operand driving the contact output should be given a reset delay of 10 ms to prevent damage of the output contact (in situations when the element initiating the contact output is bouncing, at val- ues in the region of the pickup value).

Page 71: Rs232 Faceplate Port
3.2.6 RS232 FACEPLATE PORT A 9-pin RS232C serial port is located on the B90 faceplate for programming with a computer. All that is required to use this interface is a computer running the EnerVista UR Setup software provided with the relay. Cabling for the RS232 port is shown in the following figure for both 9-pin and 25-pin connectors.
Page 72 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 B90 COM terminal (#3); others function cor- rectly only if the common wire is connected to the B90 COM terminal, but insulated from the shield.

Figure 5–36: UR ARCHITECTURE OVERVIEW The states of all digital signals used in the B90 are represented by flags (or FlexLogic operands, which are described later in this section). A digital “1” is represented by a 'set' flag. Any external contact change-of-state can be used to block an ele- ment from operating, as an input to a control feature in a FlexLogic equation, or to operate a contact output.

Various self-checking diagnostics are performed in the background while the B90 is running, and diagnostic information is stored on the non-volatile memory from time to time based on the self-checking result. Although the diagnostic information is cleared before the B90 is shipped from the factory, the user may want to clear the diagnostic information for themselves under certain circumstances.

8 THEORY OF OPERATION 8.1INTRODUCTION 8.1.1 BUS DIFFERENTIAL PROTECTION Referring to the figure below, input currents defining (through the dynamic bus replica) the bus differential zone are received by the B90 from current transformers (CTs) associated with the power system. Measuring Unit Unbiased Differential...
Page 308: Dynamic Bus Replica Mechanism
8.2.1 DYNAMIC BUS REPLICA MECHANISM The bus differential zones of the B90 allow for protecting bus sections that include circuits that are switchable between dif- ferent sections. Proper relay operation is achieved by associating a status signal with each input current. This mechanism is referred to as a dynamic bus replica.
Page 309: Differential Principle
Figure 8–2: BIASED OPERATING CHARACTERISTIC The higher slope used by the B90 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 311: Enhanced Security
8.3 DIFFERENTIAL PRINCIPLE 8.3.3 ENHANCED SECURITY In order to enhance the performance of the B90, the differential characteristic is divided into two regions having diverse operating modes as shown in following diagram. The first region applies to comparatively low differential currents and has been introduced to deal with CT saturation on low- current external faults.
Page 312: Directional Principle
8.4.1 CURRENT DIRECTIONAL PROTECTION For better security, the B90 uses the current directional protection principle to dynamically supervise the main current differ- ential function. The directional principle is in effect permanently for low differential currents (region 1 in Figure 0–1: Two Regions of Differential Characteristic) and is switched on dynamically for large differential currents (Region 2 in the same figure) by the saturation detector (see section 8.5: Saturation Detector) upon detecting CT saturation.
Page 313: Saturation Detector
8.5.1 CT SATURATION DETECTION The saturation detector of the B90 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 of that, 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 314: Output Logic And Examples
Figure 8-10 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 B90 remains stable. Figure 8-11 presents the same signals but for the case of an internal fault. The B90 trips in 10 ms (fast form-C output con- tact).

It is also assumed that the CTs have been selected without considering a B90 application, but the B90 settings are to be calculated for proper relay application. The CT data used in this example are kept to a minimum and in a generic form. The CT data does not reflect any particular notation or national standards.

Assuming 0.003 /m lead resistance and approximating the B90 input resistance for the 5A input CTs as 0.2 VA / (5 A) 0.008 , 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 321: Low Breakpoint
A combination of very high residual magnetism and a DC component with a long time constant may saturate a given CT even with the AC current below the suggested value of the lower breakpoint. The relay copes with this threat by using a 2- out-of-2 operating mode for low differential currents. GE Multilin B90 Low Impedance Bus Differential System...

C.2.2 GGIO1: DIGITAL STATUS VALUES The GGIO1 logical node is available in the B90 to provide access to as many 128 digital status points and associated time- stamps and quality flags.

C.3.4 LOGICAL DEVICE NAME The logical device name is used to identify the IEC 61850 logical device that exists within the B90. This name is composed of two parts: the IED name setting and the logical device instance. The complete logical device name is the combination of the two character strings programmed in the settings.
Page 436: Logical Node Name Prefixes
A built-in TCP/IP connection timeout of two minutes is employed by the B90 to detect ‘dead’ connections. If there is no data traffic on a TCP connection for greater than two minutes, the connection will be aborted by the B90. This frees up the con- nection to be used by other clients.
Page 437: Generic Substation Event Services: Gsse And Goose
MAC address for GSSE messages. If GSSE DESTINATION MAC ADDRESS a valid multicast Ethernet MAC address is not entered (for example, 00 00 00 00 00 00), the B90 will use the source Ether- net MAC address as the destination, with the multicast bit set.
Page 438 The B90 has the ability of detecting if a data item in one of the GOOSE datasets is erroneously oscillating. This can be caused by events such as errors in logic programming, inputs improperly being asserted and de-asserted, or failed station components.
Page 439 REMOTE IN 1 ITEM item to remote input 1. Remote input 1 can now be used in FlexLogic equations or other settings. The B90 must be rebooted (control power removed and re-applied) before these settings take effect. The value of remote input 1 (Boolean on or off) in the receiving device will be determined by the GGIO1.ST.Ind1.stVal value in the sending device.
Page 440: Ethernet Mac Address For Gsse/Goose
GSSE and GOOSE messages must have multicast destination MAC addresses. By default, the B90 is configured to use an automated multicast MAC scheme. If the B90 destination MAC address setting is not a valid multicast address (that is, the least significant bit of the first byte is not set), the address used as the destina- tion MAC will be the same as the local MAC address, but with the multicast bit set.
Page 441: Iec 61850 Implementation Via Enervista Ur Setup
The B90 can be configured for IEC 61850 via the EnerVista UR Setup software as follows. An ICD file is generated for the B90 by the EnerVista UR Setup software that describe the capabilities of the IED. The ICD file is then imported into a system configurator along with other ICD files for other IEDs (from GE or other ven- dors) for system configuration.
Page 442: Configuring Iec 61850 Settings
Transmission GOOSE dataset may be added or deleted, or prefixes of some logical nodes may be changed. While all new configurations will be mapped to the B90 settings file when importing an SCD file, all unchanged settings will preserve the same values in the new settings file.

(which also includes SSD, CID and SCD files). The ICD file describes the capabilities of an IED and consists of four major sections: • Header • Communication • IEDs • DataTypeTemplates GE Multilin B90 Low Impedance Bus Differential System C-13...
Page 444 Furthermore, it defines the capabilities of an IED in terms of communication services offered and, together with its LNType, instantiated data (DO) and its default or configuration values. There should be only one IED section in an ICD since it only describes one IED. C-14 B90 Low Impedance Bus Differential System GE Multilin...

The EnerVista UR Setup will prompt to save the file. Select the file path and enter the name for the ICD file, then click OK to generate the file. The time to create an ICD file from the offline B90 settings file is typically much quicker than create an ICD file directly from the relay.
