Also included in the suite of protective functions are single or three phase, forward or reverse power protection, breaker failure, over/under/rate of change frequency, over/undervoltage, overexcitation, and breaker monitoring and control, sequential events, fault reporting, and metering functions, all in a compact integrated system.

Standard features include:

• NEW! Ethernet communications options
• User selectable Preprogrammed Intertie Protection Logic
• Two sensitive, single or three phase, forward or reverse power elements for directional intertie power flow and islanding detection.
• Two phase over/under voltage elements for intertie voltage limits and islanding detection.
• Two neutral voltage elements for V0 detection.
• Negative sequence voltage function for reverse phase rotation or single phasing detection.
• Six over/under frequency elements for over and under frequency intertie limits and islanding detection
• Six rate of change frequency elements for islanding detection.
• Two time and instantaneous overcurrent elements that can be individually set for forward or reverse directional or non-directional control for maximum flexibility in any application.
• Sync-check and conditional voltage reclosing.
• BESTlogic provides the user with complete flexibility in configuring a protection and control system.
• Programmable LCD display allows the relay to replace local indication and control functions, such as panel metering, alarm annunciation, and control switches.
• Three independent communication ports and support for several popular protocols allow integration with distributed control systems.
• Real Time Clock with 8-hour capacitor ride-through and optional battery backup.
• Available in fully drawout half-rack case. Two Basler Electric half-rack IEDs (Intelligent Electronic Devices) can be dovetailed together to mount in a standard 19-inch equipment rack with no special mounting hardware.
• BESTCOMS GUI software available to aid in setup.
