GE Multilin F650

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 or 512 (depending on the selected model) 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.

Advanced Communications

The F650 incorporates the industry-leading communication technologies making it one of the easiest and flexible feeder protection relays for use and integration into new and existing infrastructures. 

The F650 provides optional Parallel Redundancy Protocol (PRP), High Availability Seamless Ring (HSR) (IEC 62439-3) and also Rapid Spanning Tree Protocol (RSTP) (IEEE 802.1D) to increase network availability and reliability for critical applications.

The F650 includes up to three communication ports that operate simultaneously. Redundant ports are also available for special applications.

The F650 supports popular industry leading standard protocols enabling easy, direct integration into electrical SCADA and HMI systems. The protocols supported by the F650 include:

IEC 61850 Edition 2

DNP 3.0

Modbus RTU

Modbus TCP/IP

IEC 60870-5-103 and IEC 60870-5-104

PRP & HSR (IEC 62439-3)

RSTP (IEEE 802.1D)

IEEE 1588 (PTP) for time synchronization

The F650 provides integration with 61850 standard edition 2. IEC 61850 allows for the seamless connection of IEDs from multiple vendors. 

In addition to device interoperability, these protocols are designed to control the substation via a LAN instead of through discrete wiring to an RTU.

Example of redundant HSR and PRP Architecture

Redundancy protocols (PRP and HSR) can be used for various networking architectures including combined PRP/HSR topologies.

EnerVista Software

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.

The 650 Logic Configuration software is a powerful programming logic engine that provides the ability to create customized protection and control schemes thereby minimizing the need, and costs associated with auxiliary components and wiring.
