Page 13: Introduction
Through BESTCOMSPlus, all BE1-11g settings and logic can be retained in a file for printing or uploading to other BE1-11g protection systems. Oscillography and sequential events records can be retrieved from a BE1-11g, viewed, and printed.
Page 14: Features
General Features HMI (Human-Machine Interface) Each BE1-11g has a front-panel display and LED indicators. Protection systems in an H or P style case have five LED indicators: Power Supply Status, Relay Trouble Alarm, Minor Alarm, Major Alarm, and Trip. Protection systems in a J style case have 12 LED indicators: Power Supply Status, Relay Trouble Alarm, Minor Alarm, Major Alarm, Trip, Select Control Switch, Operate Control Switch, and Indicator 1 through 7 (programmable in BESTlogicPlus).
Page 15 NTP synchronizes the real-time clock to network time servers through the Ethernet port. BESTCOMSPlus is used to establish the priority of time reference sources available to the BE1-11g, IRIG-B, NTP, DNP, and RTC (real-time clock). The NTP address is set using BESTCOMSPlus.
Page 16 Reporting of power quality, energy data, and general status is also provided. Alarms Extensive self-diagnostics will trigger a fatal relay trouble alarm if any of the BE1-11g core functions are compromised. Fatal relay trouble alarms are not programmable and are dedicated to the Alarm output (OUTA) and the front panel Relay Trouble LED.
Page 17 BESTwave is included on the BE1-11 product CD. Sequence of Events Recorder A Sequence of Events Recorder (SER) records and time stamps all BE1-11g inputs and outputs as well as all alarm conditions monitored by the BE1-11g. Time stamp resolution is to the nearest half-cycle. I/O and Alarm reports can be extracted from the records as well as reports of events recorded during the time span associated with a specific fault report.
Page 18 9424200994 Rev U Note BE1-11g protection systems enabled for IEC-61850 communication (style Gxxxx5xxxxxxxx) have their frequency protection elements fixed at four underfrequency elements, two overfrequency elements, and two frequency rate-of-change elements. Instantaneous Overcurrent (50) Protection Directional overcurrent protection is provided by six instantaneous overcurrent elements. Digital signal processing filters out unwanted harmonic components while providing fast overcurrent response with limited transient overreach and overtravel.
Page 19 Resistance Temperature Detector (49RTD) Protection Fourteen resistance temperature detector elements provide over/undertemperature protection in applications where a remote RTD module is connected to the BE1-11g via Ethernet or RS-485 cable. For more information, refer to the RTD Module chapter. Analog Input Protection Eight analog input protection elements monitor external analog input signals when two remote RTD modules are connected via an Ethernet or RS-485 cable.
Page 20: Model And Style Number Description
The style number describes the options included in a specific device and appears on labels located on the front panel and inside the case. Upon receipt of a BE1-11g, be sure to check the style number against the requisition and the packing list to ensure that they agree.

VPP/Hz for VT connection = 3W, 4W, AB, BC, CA and VPN/Hz for VT connection = AN, BN, CN. For more information, refer to the Configuration chapter. Nominal voltage for the BE1-11g is defined as a phase-to-neutral quantity. Nominal V/Hz depends on the sensing voltage (VT) connection, nominal voltage, and nominal frequency settings. Nominal V/Hz is calculated as the nominal voltage divided by nominal frequency.
Page 56 If a target is enabled for the element, the BE1-11g will record a target when the Trip output becomes true. See the Fault Reporting chapter for more information about target reporting.

Page 125: Directional Overcurrent (67) Protection
CT input (IG) is in phase with the calculated I Each of the four internal polarization methods has designated internal bits that are used in the BE1-11g for direction identification, one for forward direction and one for reverse direction. Combined, these eight bits are referred to as the directional status byte and are used to control the various overcurrent elements.
Page 126 The neutral overcurrent elements can be supervised by various polarization methods using either or both zero-sequence and negative-sequence quantities. This is necessary depending on the application and fault conditions applied to the BE1-11g. For example, negative-sequence polarizing can be used when zero-sequence mutual coupling effects cause zero-sequence polarizing elements to lose directionality. In addition, high Z ground faults might cause values of zero-sequence voltage too low to measure during a fault, making zero-sequence polarization unreliable.
Page 127: Maximum Torque Angle And Directional Tests
Note that (not forward) does not necessarily imply reverse. Sufficient current and voltage must be present to declare direction. Internally, the BE1-11g also uses several constant limits to determine if the system levels are adequate to perform reliable directional tests and set directional bits. See Table 42.
Page 128: Theory Of Using Sequence Impedances For Fault Direction
Negative- and zero-sequence voltage is highest at the fault location, and lowest at the source. This affects how the BE1-11g uses the angle of maximum torque to prevent tripping for unusual load flow.
Page 129 Equation 19. Impedance with Small V and V Source Voltages The calculations in the BE1-11g are account for the negative factor in the above equation and hence a 180° phase shift is implemented in the BE1-11g firmware so that a correct forward/reverse decision is made.

In some applications, the zone of protection may include only the generator. In other applications, a power transformer may be included in the generator zone of protection. If a fault is detected, the BE1-11g initiates a trip signal to isolate the protected zone. This action limits equipment damage and minimizes impact on the power system.

Page 145: Power (32) Protection
To clarify the difference between Three of Three and Total Power modes, assume that Two of Three mode has been selected and the pickup setting is 30 watts. Therefore, the BE1-11g picks up when two of the three phases have exceeded 30 watts. Alternately, if two phases are zero (0) watts and the third phase is 70 watts, the BE1-11g does not pickup because two of the phases have not exceeded the pickup threshold required for operation in Two of Three mode.
Page 146 In addition to exceeding the power pickup threshold, direction of power flow (forward or reverse) must match the directional setting for the 32 element to operate. In the BE1-11g, the forward and reverse directions are defined by the polarity voltage and current connections to the BE1-11g as shown in Figure 82.

Maximum data capture resolution is 32 samples per cycle and is user selectable. The BE1-11g can store up to 2,048 cycles of data at 8 samples per cycle or 512 cycles of data at 32 samples per cycle. Refer to Table 81 for Oscillographic Records Settings.
Page 227: Distance To Fault
For more information, refer to the BESTnetPlus chapter. Distance to Fault The BE1-11g calculates distance to fault each time a fault record is triggered. Distance to fault is calculated and displayed based on the power line parameters entered using BESTCOMSPlus or the front-panel interface.
Page 228 9424200994 Rev U To perform the actual distance calculation, the BE1-11g first must determine the faulted phase. Faults can be categorized depending on the lines faulted. The various categories are LLL, LL, LLG, or LG where L = line and G = ground.

Page 656: Rtd Module Communications Setup Procedure
An IP address is assigned to the RTD module in all cases even if the connection between the RTD module and the BE1-11g will be RS-485. Assigning an IP address to the RTD module gives the user the option to save a settings file and to view the serial number and firmware version of the RTD module using BESTCOMSPlus.
Page 657 Perform this step if the RTD Module is connected to the BE1-11g via a direct Ethernet connection. The BE1-11g communicates with the RTD Module only if its Active IP Address is a nonzero value. To confirm/set the IP Address, open the Ethernet screen under Communication, Configure and de-select the Use DHCP box.
