GEK-113000-AF F650 DIGITAL BAY CONTROLLER 2-1F650 Digital Bay ControllerChapter 2: Product DescriptionGEGrid SolutionsPRODUCT DESCRIPTION2.1 F650 OverviewF650 is a protection, control, monitoring, metering and registering unit, suitable for many different applications, such asmain protection for distribution feeders and transmission lines, as well as backup protection for transformers, busbars,capacitor banks, etc.Overvoltage and undervoltage protection, overfrequency and underfrequency protection, breaker failure protection,directional current supervision fault diagnostics and programmable logic functions are provided.This relay also provides phase, neutral, ground and sensitive ground, instantaneous and time overcurrent protection. Thetime overcurrent function provides multiple curve shapes or FlexCurves™ for optimum co-ordination. Automatic reclosing,synchrocheck, and line fault locator features are also provided.Voltage, current, power, and energy metering is built into the relay as a standard feature. Current parameters areavailable as true RMS magnitude, or as RMS magnitude of undamental frequency and angle (phasor).Diagnostic features include a sequence of records. The internal clock used for time-tagging can be synchronized with anIRIG-B signal or via SNTP, DNP or Modbus protocol over the Ethernet port. From firmware version 7.00 and above, IEEE1588 time protocol is also available. Precise time stamping allows the sequence of events to be determined throughout thesystem. Oscillography data capture may be set to record the measured parameters before and after the event for viewingon a personal computer (PC). These tools significantly reduce troubleshooting time and simplify report generation in theevent of a system fault.A faceplate RS232 or USB port may be used to connect to a PC for programming settings and monitoring actual values.A variety of communications modules are available. Two rear RS485 ports allow independent access by operating andengineering personnel. All serial ports use the Modbus® RTU protocol. Optional communications modules include a100BaseFX Ethernet interface which can be used to provide fast, reliable communications in noisy environments.
