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 Vx input. Rate of change can be set to operate on positive, negative, or “either”. 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.
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.

Page 45: Contact Inputs And Outputs
This section describes the function and setup of each input and output. Contact-Sensing Inputs A BE1-11g in a J type case has seven contact inputs to initiate BE1-11g actions. Four contact inputs are provided in an H or P type case. Each isolated input requires an external wetting voltage. The nominal voltage(s) of the external dc source(s) must fall within the BE1-11g dc power supply input voltage range.
Page 46 9424200994 Rev N Remove the BE1-11g from service and de-energize it. The contact-sensing input jumpers are located behind the rear terminal blocks that are used for input connections. Using a 7/64” hex tool, remove the rear terminal block(s) associated with the input(s) that you want to configure.

Page 55: Overexcitation (24) Protection
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. For VT connections equal to 3W, 4W, AB, BC, CA, the nominal voltage (phase-neutral value) must be converted to a phase-phase value by multiplying by the square root of 3.
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.

Before any relay output can occur, there must first be an initiating signal from external contacts. Two possible initiating signals are either the 52 Breaker Fail Initiate (52BFI) signal or the 50 Breaker Fail Initiate (50BFI) signal. Contact sensing circuitry allows the BE1-11g to monitor external contacts for the presence of these signals.

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 116 9424200994 Rev N The BE1-11g maintains memory voltage for 20 cycles to allow tripping for close in faults. When using memory voltage polarization, the BE1-11g assumes nominal system frequency. Negative-Sequence Polarization is used to test directionally for all fault types except three-phase faults.
Page 117: 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 38.
Page 118: 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 119 Equation 11. 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.

Alternately, if two phases are zero (0) watts and the third phase is 50 watts, the BE1-11g will not pickup because two of the phases have not exceeded the single phase pickup threshold required for 3 of 3 operation. All three phases must exceed the single-phase pickup threshold for operation to occur.

The following paragraphs describe how the BE1-11g is programmed to define which protective functions log targets. Target Settings Targets are enabled using BESTCOMSPlus.
Page 208: Fault Reports
When a new fault summary report is generated, the BE1-11g discards the oldest of the 255 events and replaces it with a new one. Each fault summary report is assigned a sequential number (from 1 to 255) by the BE1-11g. After event number 255 has been assigned, the numbering starts over at 1.
Page 209 9424200994 Rev N BE1-11g protection systems have three identification fields: Device ID, Station ID, and User ID. These fields are used in the header information lines of the fault reports. Refer to the BESTCOMSPlus Software chapter for information on BE1-11g identification settings.
Page 210 • Event Type. This line reports the type of event that occurred. There are five event categories: Trip: A fault was detected as defined by the pickup expression and the BE1-11g tripped to clear the fault. Pickup: A fault was detected as defined by the pickup expression but the BE1-11g never tripped indicating that the fault was cleared by another device.
Page 211: Oscillographic Records
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 76 for Oscillographic Records Settings.
Page 212: Distance To Fault
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. Table 77 provides the power line operating settings.
Page 213 The two-cycle wait time allows line transients to settle to provide results that are more accurate. 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.

The answer to the question is yes and no. In general, once the fault goes away the output contacts open. The BE1-11g does offer an option to ensure that the contact will stay closed for at least 200 milliseconds. See the Contact Inputs and Outputs chapter for additional information on that function.
Page 558: Features
Communications Is the IRIG signal modulated or demodulated? The BE1-11g accepts an IRIG-B signal that is demodulated (dc level-shifted digital signal). See the Specifications chapter for additional information.
Page 559: Troubleshooting
Why do I keep getting access conflict errors when I attempt communication with the BE1-11g? If you try to gain access to more than one port at a time, an access conflict results. The BE1-11g has three communication ports: front-panel USB, rear panel optional Ethernet, and rear panel RS-485. Each communication method has its own access.
Page 560: Inputs And Outputs
When activity at a port is no longer required, access should be terminated. Obtaining data or reports from the BE1-11g never requires password access. The security log is an exception, as it requires Administrator access.

Page 595 User Tables Time Dial Setting Cross-Reference Although the time characteristic curve shapes have been optimized for each BE1-11g, time dial settings of Basler Electric protection systems are not identical to the settings of electromechanical induction disk overcurrent relays. Table 253 helps you convert the time dial settings of induction disk relays to the equivalent setting for Basler Electric protection systems.
Page 596 When using the 46 curve, the user should convert the continuous I rating data to actual secondary current at the BE1-11g.
