Basler BE1-700, Digital Protective Relay

BRAND : Basler

• 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.
