Multilin R650

Advanced recloser controller for distribution networks

The Multilin™ R650 recloser controller delivers critical protection, monitoring and control for distribution automation applications. The Multilin R650 provides automatic network configuration enabling operators to reduce outage duration and recover sections of a medium voltage (MV) network for increased reliability in secondary distribution systems.

With a focus on connectivity and security, the R650 supports the latest in communications technologies and protocols, and provides standard security tools to help ensure that device integration into new or existing SCADA, OMS or DMS is as simple and secure as possible. As a member of GE’s Multilin 650 family of field proven protection and control devices, the R650 Provides simplified management as operators can use the same platform both inside and outside the substation.

Protection & Control

Advanced Protection and Control

The Multilin R650 offers a complete range of standard and advanced protection elements with multiple stages and wide setting ranges. The recloser controller provides comprehensive directional and non-directional overcurrent protection, along with optional single phase tripping and reclosing to limit system impact and improve reliability. A synchronism check function ensures that the voltages are within safe limits before allowing manual closing and auto reclose operations. Additionally, voltage and frequency protection elements may be used to disconnect generation connected to the feeder. The R650 includes six voltage inputs to monitor voltages on both sides of the recloser thereby delivering a safer level of performance.


Driving Electronics Module

At the heart of the R650 design is the driving electronics module that accurately matches the requirements of the recloser device with the controller outputs. This module ensures minimum delay between the R650 output signals and the breaker operation. Through intelligent design, this reliable performance is achieved utilizing minimal power, providing operators with true multiple shot capability.

The driving electronics module design has been extensively tested and validated to ensure optimum performance and facilitate high-speed, multi-shot capability. Test results indicate that the module enables the trip capacitors to maintain sufficient charge voltage to perform 4 cycles of close and trip fast.

From simple automation to advanced analytics, the R650 provides the flexibility and scalability required to meet unique application requirements.

Simple loop recloser automation schemes

This is a logic-based automation scheme for self-healing networks. This type of scheme is generally used for providing faster fault isolation and restoration.

Individual recloser controllers make decisions for restoration based on the restoration logic that is programmed into the controllers. This results in quick isolation of the faulty section and automatic restoration thereby minimizing impact on other neighboring customers.

Advanced loop recloser automation schemes

The recloser controllers can provide data to remote SCADA, Outage Management Systems (OMS) and Distribution Management Systems (DMS). These systems manage the network automation process by utilizing the recloser controller data for running FDIR/FLISR and taking restoration decisions dynamically.


EnerVista Software

The EnerVista™ Suite is an industry-leading set of software programs that simplifies every aspect of using the R650. The EnerVista suite provides all the tools to monitor the status of the recloser, maintain the controller, and integrate information measured by the R650 into DCS or SCADA monitoring systems.
