ABB REF542plus is a feeder terminal and a compact protection,control,measurement and monitoring terminal for distribution systems.The following is a detailed introduction to ABB REF542plus:

1.Product Overview

ABB REF542plus feeder terminal has a range of protection and management functions,which can perform multifunctional protection and switchgear control in real time.It is suitable for the protection and control of feeders,transformers and motors,or only for switchgear control.

2.Main functions

Protection and fault location:

Provides a variety of protection functions such as surge blocking,instantaneous overcurrent,overcurrent timing,etc.,to protect system components from current and voltage anomalies.

It has a fault locator function to help quickly locate and solve faults.

Measurement and control:

Electrical parameters such as current and voltage can be measured and displayed in real time.

Provides control functions to remotely control the opening and closing operations of switchgear.

Monitoring and diagnosis:

Real-time monitoring of primary equipment and self-diagnosis functions,including maximum and average currents during observation,sum of interrupted currents,operating time,etc.

Equipped with self-diagnostic program,it can continuously check the status of hardware and software modules and trigger alarms in case of faults.

Power quality function:

Provides power quality monitoring functions such as harmonic analysis,voltage fluctuation and flicker.

Communication function:

With a variety of communication interfaces,such as Ethernet interface,optical input port,etc.,it can realize communication with substation automation system or other equipment.

III.Technical features

Human-machine interface:

Equipped with a large multi-language LCD display,which can display single-line diagrams,text information and menu text.

The human-machine interface and the basic unit are separated,and the installation is flexible and changeable.

Analog input and output:

Provide analog input modules for connecting primary current and voltage signals.

Optional analog input module 4-20mA and analog output module 0(4)-20mA.

Binary input and output:

Provide binary input and output modules for connecting external processes.

Each binary input and output module is equipped with a watchdog contact that is triggered in the event of a fault or power failure.
