ABB REF542plus Feeder Terminal

ABB REF542plus Feeder Terminal Supplier and Exporter in India

ABB REF542plus Legacy Spare, Replacement and Upgrade Enquiries

ABB REF542plus is a digital feeder terminal used for protection and control of medium-voltage switchgear. It can be configured for feeder, transformer, motor and bay-control applications.

Description

ARP IMPEX supplies and exports ABB REF542plus feeder terminals for medium-voltage switchgear, substations and existing ABB protection and control systems.

REF542plus combines protection, measurement, monitoring, control, communication and self-diagnostics in a single unit. Although ABB calls it a feeder terminal, the platform is not limited to feeder protection. It can also be configured for transformer protection, motor protection and switchgear bay control.

The terminal is used with both air-insulated and gas-insulated medium-voltage switchgear. Depending on the original configuration, REF542plus can handle protection functions together with circuit-breaker control, interlocking, measurements, alarms, events and communication with a substation automation system.

ABB supplied REF542plus with different hardware and software combinations, so the complete order code is important when checking an existing unit.

For ABB REF542plus price and availability, send us the complete part number, clear nameplate photograph, quantity and destination country. ARP IMPEX can assist with part-code checking, legacy spare enquiries and export quotations.

The exact I/O arrangement, communication interface and protection functions should be checked from the installed REF542plus order code.

Features

• Feeder protection
• Transformer protection
• Motor protection
• Bay control
• Circuit-breaker control
• Current and voltage measurement
• Equipment and switchgear monitoring
• Programmable interlocking
• Alarm and event handling
• Local graphical HMI
• Communication with substation automation systems
• Internal self-diagnostics
• Configurable protection and control logic

ABB designed the protection and control functions as configurable software modules, allowing the same REF542plus platform to be used for different medium-voltage applications.

Applications

REF542plus can be used for:

• Medium-voltage feeder protection
• Incoming feeder panels
• Outgoing feeder panels
• Cable feeder protection
• Transformer protection
• Motor protection
• Circuit-breaker control
• Switchgear bay control
• Industrial distribution systems
• Utility substations
• Air-insulated switchgear
• Gas-insulated switchgear
• Bay interlocking
• Substation automation
• Existing ABB medium-voltage switchgear

Its ability to combine protection and bay control in one device is one of the reasons REF542plus was used across several types of medium-voltage panels rather than only conventional feeder applications.

ABB REF542plus Configurations

REF542plus is one configurable product platform rather than a family of separate models such as REF541, REF543 and REF545.

ABB supplied the terminal with different hardware and software combinations. The order code identifies the required hardware and software arrangement for the particular application.

Protection packages documented for the platform include different functionality levels for basic, multifunction, differential and distance-protection applications. The installed package determines which protection functions are available in a particular terminal.

ABB REF542 and REF542plus

REF542plus followed the earlier ABB REF542 bay control and protection unit.

ABB developed REF542plus as the later generation of REF542 with additional functions while retaining a similar protection and control concept. ABB also documented REF542plus as a recommended replacement route for older REF542 installations.

The two products should still be identified separately when requesting a quotation:

• ABB REF542 – earlier bay control and protection unit
• ABB REF542plus – later feeder terminal and multifunction protection/control platform

ABB REF542plus Legacy Spare and Upgrade Support

ABB lists REF542plus as a legacy product, but continues to provide lifecycle information for the installed base. ABB also lists REF542plus under its Maintenance Exchange Unit service.
