The BE1-851 is a multifunction, numeric relay that provides a comprehensive mix of protective, control and metering functions in an integrated system. This system is suitable for any nondirectional overcurrent application including feeder applications, generator applications, cogeneration applications, and trans- former backup. The BE1-851 has the unique ability to provide specific current response characteristics. It does this in three different ways: The Fundamental twenty-four sample per cycle Digital Signal Processing (DSP) algorithm provides rejection of harmonics and low transient overreach. The RMS DSP algorithm provides true wide band RMS measurement. The Average DSP algorithm provides a flat response characteristic over a wide frequency range. These characteristics are independently settable for phase and neutral quantities. The unit has one set of three phase and neutral current sensing inputs to provide all common protective functions for substation and feeder applications. Selection of sensing input Type G offers additional application flexibility by providing the Protection Engineer with three additional ground currents in lieu of the negative sequence function. The half rack case is fully drawout with current circuit shorting provisions. Two Basler Electric half rack IEDs (Intelligent Electronic Devices) such as primary and backup BE1-851 or the BE1-951 or BE1-GPS100 can be dovetailed together to mount in a standard 19" equipment rack with no special mounting hardware. The S1 and F1 cases allow savings in modernizing existing facilities. One overcurrent or reclosing relay can be removed from the panel and replaced with a state-of-the-art communicating multifunction relay. Remaining relays can be removed or left in place for backup. Available adapter plates broaden the types of relays that can be readily replaced with no panel cutting. Three independent communications ports, along with built-in support for ModbusTM and other common protocols, provide easy access to integrating the protection, control, metering, and status monitoring functions into a substation automation system. The standard IRIG-B port provides time synchronization from a master clock. Real time metering provides amp and unbalance loading telemetry for the protected circuit. Contact sensing inputs and alarm monitoring functions provide real time status information. Remote control is pro- vided by virtual control and selector switches with select-before-operate control of programmable outputs. BESTlogic BESTlogic programmable logic provides the user with high flexibility in configuring a protection and control system. Each of the protection and control functions in the BE1-851 is implemented as an independent function block that is equivalent to its single function, discrete device counterpart. Each independent function block has all the inputs and outputs that the discrete component counterpart might have. Figures 6A and 6B show each of the independent function blocks available for use in the BE1-851. Programming BESTlogic is equivalent to choosing the devices required by your protection and control scheme and drawing schematic diagrams to connect the inputs and outputs to obtain the desired operational logic. The BE1-851 relay can store, as user settings, one user programmable, custom logic scheme. To save you time, several preprogrammed logic schemes have also been provided. Any of the preprogrammed schemes may be copied into the logic settings without making any additional BESTlogic settings. BESTlogic provides the protection engineer with the flexibility to set up this powerful multifunction system with the same freedom that was once enjoyed with single function, discrete devices. It is no longer neces- sary to compromise your standard protection and operating practices to deal with the limitations in programmability of previous multifunction devices. Figures 2A, 2B, 2C, and 3 show typical external connections, and Figures 5A, 5B and 5C show rear panel connections.
