• Proven algorithms based on more than 50 years of relaying
experience and more than 30 years of reliable digital relaying design.
• One relay for most applications.
• All of the advantages of a fully numeric product in an economical
“voltage only” protection package.
• Oscillography, Sequence of Events, and Metering are added when
single function voltage relays are replaced with the BE1-700V.
• Zero-sequence voltage (3V0) used to detect single-phase ground
faults on high resistance or ungrounded systems can be calculated
based on the applied three-phase four-wire sensing voltage, or
applied from a separate zero sequence source (optional VX input).
• Optional four-shot recloser, including a pilot initiate path and
auxiliary voltage input, replaces existing network (transmission,
subtransmission) automatic reclosing schemes.
• Optional BESTnet™ Ethernet package provides metering and
status web pages, settings and configuration via Ethernet, and email
notification of user-defined events.
• Communications ports: one front RS-232, one rear RS-485, one
rear IRIG port, and one rear Ethernet port.
• Communications protocols: Modbus™/TCP and ASCII.
