ABB RER620 Models and Configurations

ABB RER620 is one advanced recloser protection and control platform rather than a family containing many separate model numbers.

ABB documents one standard feeder protection and recloser control configuration, with the final functions and hardware determined by the complete order code. The application can then be adjusted using ABB PCM600.

The ordering structure includes two functional application variants:

ABB RER620 Functional Application A – RA01

Functional Application A is used for single- and dual-source recloser applications with six voltage inputs.

It can be ordered with:

• Single-phase or three-phase tripping
• Basic or expanded binary I/O
• Ethernet communication
• Serial communication options
• IEC 61850
• DNP3
• Modbus
• IEC 60870-5-101/104, depending on communication selection

This is the main RER620 configuration used with feeder and recloser control applications.

ABB RER620 Functional Application B – RA02

Functional Application B is also intended for single- and dual-source applications and is associated with G&W and other supported recloser arrangements.

ABB notes that this option became available with software version 1.3 or later. The exact recloser interface, power driver and UPS requirement should be confirmed against the complete order code.

For replacement enquiries, it is better to quote against the full RER620 order code instead of selecting only RA01 or RA02.

ABB specifically highlights single- and three-phase tripping, high-impedance fault detection, integrated loop control, scalable I/O and IEC 61850/GOOSE communication among the main RER620 capabilities.

Single-Phase and Three-Phase Recloser Control

RER620 can operate three poles together or individual poles, depending on the ordered relay and recloser arrangement.

Single-phase operation is useful in distribution systems where a temporary fault affects only one phase and opening all three phases is not required.

RER620 supports up to five programmable autoreclose shots. Different fast and delayed operating sequences can be set according to the feeder protection philosophy.

Typical applications include:

• Rural overhead feeders
• Utility distribution lines
• Recloser sectionalising points
• Midpoint reclosers
• Tie-point reclosers
• Feeders with downstream fuses

High-Impedance Fault Detection

RER620 can be ordered with high-impedance fault detection, which is useful for detecting fault conditions that may produce current too low for normal overcurrent elements.

Typical examples include:

• Downed overhead conductors
• Conductors touching high-resistance surfaces
• Weak ground faults
• Faults where conventional overcurrent protection may have limited sensitivity

RER620 uses its sensitive fourth CT input for sensitive earth-fault and high-impedance fault functions.

For an ABB RER620 high impedance fault detection relay quotation, the exact order code and CT arrangement should be checked.

Integrated Loop Control

Integrated loop control is one of the important differences between RER620 and a basic recloser relay.

RER620 can be used at:

• Sectionalising reclosers
• Midpoint reclosers
• Tie-point reclosers

The relay can react to voltage conditions around the feeder and automatically change the network arrangement after a fault. ABB describes this as an automatic loop restoration function that can work without communication between the individual recloser controls in the basic loop-control scheme.

Where communication between relays is available, IEC 61850 GOOSE messaging can also be used for fault detection, isolation and restoration schemes.

This makes RER620 relevant for searches such as:

• ABB automatic loop control relay
• ABB feeder restoration relay
• ABB FDIR recloser relay
• ABB RER620 tie-point recloser control

Distributed Generation Applications

RER620 can be used in distribution networks containing distributed generation.

ABB includes built-in logic for situations where energising a distributed-generation interconnection transformer creates transformer inrush current. Protection elements can be temporarily blocked or made less sensitive to prevent unnecessary recloser operation.

Typical applications include:

• Solar power connections
• Wind generation connections
• Captive generation
• Distributed generation feeders
• Utility networks with reverse power flow
• Renewable energy distribution networks

ABB GridShield Recloser Applications

RER620 has been widely associated with ABB GridShield reclosers.The relay’s Universal Power Driver can control magnetic actuators used in three-phase reclosers. ABB also specifies an external UPS arrangement when RER620 is used with ABB GridShield or G&W Viper reclosers.

For an ABB RER620 GridShield replacement, buyers should share:

• RER620 order code
• GridShield recloser model
• Relay nameplate
• UPS details
• Existing wiring or panel information
• PCM600 configuration, if available

Remote Monitoring and SCADA Communication

RER620 can communicate with utility automation and SCADA systems using several communication protocols.

Depending on the ordered communication module, these include:

• IEC 61850
• DNP3 Level 2+
• Modbus
• IEC 60870-5-101
• IEC 60870-5-104
• PG&E 2179

IEC 61850 GOOSE messaging can also be used for fast peer-to-peer communication between protection and control devices.

RER620 supports remote recloser control and makes fault records, waveform information, measurements, events and settings available locally or remotely.

Applications

ABB RER620 is commonly used for:

• Advanced recloser protection
• Overhead-line feeder protection
• Underground cable feeder protection
• Single-phase recloser control
• Three-phase recloser control
• Automatic feeder reclosing
• Sectionalising recloser applications
• Midpoint recloser applications
• Tie-point recloser applications
• Automatic loop restoration
• Feeder fault location
• Fault detection and isolation
• Service restoration
• High-impedance fault detection
• Sensitive earth-fault protection

ABB RER620 Replacement and REC615 Upgrade

RER620 remains important for the installed base, particularly where utilities require a matching replacement, maintenance spare or upgrade of an existing recloser installation.

ABB now states that there will be no new releases of RER620, and the new Grid Automation REC615 represents the next step for RER620 applications. The new REC615 combines the functions of the previous REC615, RER615 and RER620 platforms.

For RER620 applications, ABB provides the new REC615 in a wide-size version corresponding to the RER620 mechanical size and analogue/binary channel capability.

However, an RER620-to-REC615 replacement should not be selected only by enclosure size. The following should also be checked:

• Existing RER620 order code
• Single- or three-phase recloser operation
• CT and voltage inputs
• Binary I/O
• Recloser actuator
• Universal Power Driver arrangement
• External UPS
• Communication interface
• SCADA protocol
• Existing PCM600 logic and settings

ABB notes that the RER620 UPD arrangement is replaced by an external actuator interface module when the new REC615 is used with GridShield.

For an ABB RER620 replacement relay or RER620 to REC615 upgrade, send the existing nameplate and complete order code first.
