  • Metering: V I Hz W VA PF
  • Demand: Ia , Ib , Ic , Ig, Isg, I2, MW, MVA
  • Configurable graphical HMI interface
  • Alarm Panel
    The F650 provides advanced monitoring and metering that includes:

    VT Fuse Failure
    Use the VT Fuse Failure feature to issue an alarm and/or to block voltage driven protection functions that can operate incorrectly due to an abrupt partial or total voltage loss. This loss is caused by the voltage transformers secondary circuit protection fuse failure. Different methods are used to detect the different types of VT fuse failure.

    Trip Circuit Monitoring
    F650 can be used to monitor the integrity of both the breaker trip and closing coils and circuits. The supervision inputs monitor both the battery voltage level, while the outputs monitor the continuity of the trip and/or closing circuits, by applying a small current through the circuits.

    Basic Metering
    Ia, Ib, Ic, Ig, Isg, Va, Vb, Vc and Vx signals are available locally and remotely and can be stored in the oscillography record or data logger.

    Event Recording and Oscillography
    The F650 is capable of storing 479 time-tagged events (1 ms tagging), to help with troubleshooting. The trigger point, the channels, and sampling rate of the oscillography files are user programmable features. Up to five seconds at maximum sample rate can be stored.

    Breaker Arcing Current (I2t)
    The relay estimates the total interrupted current as an accumulation of the RMS current measured during the time period taken to open the breaker after a trip. It calculates the per-phase wear on the breaker contacts to establish a threshold. When the breaker maintenance threshold is exceeded the relay can be set to trigger an alarm.

    The F650 includes up to three communication ports that operate simultaneously. Redundant ports are also available for special applications. F650 features an RS232 front port (COM2) and a choice of rear RS485, plastic/glass fiber optics (COM1 and COM2). Additionally, this module may incorporate a port for CAN bus communications, used for the connection to the remote CAN BUS I/O module. F650 COM3 features 10/100 BaseTX and 100 Base FX single or redundant Ethernet ports.

    Protocols supported by the F650 include IEC61850, DNP 3.0, Modbus RTU, ModBus TCP/IP and IEC 60870-5-104. These protocols make it easy to connect to a Utility automation system and are integrated into the F650, eliminating the need for external protocol converter devices.

    Enhanced IEC 61850 and DNP3.0, and incorporated IEC 60870-5-103 protocol — all built on 10 years of GE Multilin leadership in open communication standards. Embedded IEC 61850 & IEC 60870-5-103 eliminates the need for external protocol converters. Implemented Daylight Savings Time setting enables use of local time when synchronizing with SNTP protocol or IRIG-B.

    The EnerVista™ Suite is an industry-leading set of software programs that simplifies every aspect of using the F65 relay. The EnerVista™ suite provides all the tools to monitor the status of your the protected asset, maintain the relay, and integrate information measured by the F650 into DCS or SCADA monitoring systems. Convenient COMTRADE and Sequence of Events viewers are an integral part of the 650 Setup software included with every F650 relay, to carry out postmortem event analysis to ensure proper protection system operation.

    Access Control
    Multilin devices and relays are designed with simple but powerful security to enable reliability and compliance for virtually any project or implementation. With support for multi-level permissions and multi-factor supervisory controls, Multilin devices can help you manage the integrity of your system during commissioning, testing, implementation, and beyond. The 650 Family provides separate authentication for settings and commands to the system. In addition, as discrete authentications for local and remote access, it also provides a supervisory control factor that can lock or unlock a device for configuration changes and other modifications.
    Intrusion Detection
    Multilin’s family of protection and control products can also help enable your security perimeter and intrusion detection programs. By providing essential alarming and logging of critical events, Multilin devices can help you detect potential breaches within your system and allow you to respond quickly and effectively. Specifically, unsuccessful access attempts are logged, alarmed, and lead to potential attackers being locked out. This ensures the reliability of your system during questionable activity.control factor that can lock or unlock a device for configuration changes and other modifications.
    Auditing and Reporting
    With the Security Audit Trail reporting feature and support for Event logging of key activities such as configuration changes, Multilin devices can help ensure device and protection system integrity, and perform forensic auditing of activities and changes for compliance.
