Product Introduction

GE F650BABF2G0LOSHE Feeder Management Relay. The GE F650 is a digital protection relay designed for protection, control and automation of feeders or related applications. It provides high-speed protection and control for feeder management and bay control applications. The F650 incorporates industry-leading communication technology, making it one of the simplest and most flexible feeder protection relays available for use on both new and legacy infrastructure. It includes up to three communication ports that can operate simultaneously, and redundant ports are also available for special applications. The F650 supports popular industry-leading standard protocols for easy and direct integration into electrical SCADA and HMI systems.

The Multilin F650 Feeder Protection Relay provides high-speed protection and control for feeder management and bay control applications and features a large LCD and single-line diagram for building bay monitoring and control for a variety of feeder arrangements, including ring bus, double breakers or breakers and half breakers.

Distributed Generation (DG) Interconnection Protection, Including Active and Passive Islanding Prevention

The F650 provides high-speed protection, feeder management and bay control applications, including overcurrent protection, instantaneous and time overcurrent functions for phase, neutral, ground/sensitive ground and negative sequence currents. A variety of time curves are available, including IEEE/ANSI®, IEC A/B/C/Long Delay/Short Delay Inverse, GE IAC, I2t, Timed Rectification curves and four user-programmable curves. Directional monitoring is available during phases, including neutral, ground and sensitive ground currents. The neutral/ground directional element can be programmed to operate on zero sequence voltage, ground sensitive current or dual polarization.
Over/Under Frequency Protection

The F650 provides a six-level over- and under-frequency element improvement network based on voltage or frequency (grid) stability load shedding techniques. It also allows for backup protection and tripping circuit breakers to directly protect feeders and other frequency sensitive electrical equipment. The frequency change rate protection (df/dt) element protection included in the F650 protects against disturbances caused by load shedding. Zero sequence directional applications of the power meter include ground fault protection in solidly grounded transmission networks, grounded/ungrounded/resistance grounded/resonant grounded distribution networks. The zero sequence directional element of this power meter responds to zero sequence power by specifying the characteristic angle of the voltage and current components in a specified direction. The angle can be set in all four quadrants and the power can be either active or reactive. Thus, the element can be used for forward sensing or for reverse ground faults in inductors, resistors or resistance networks. The opposite time characteristic allows for time coordination of the elements in the network.
