1.Product Overview

ABB REF542PLUS integrates protection,control,measurement and status monitoring functions,and is suitable for distribution network automation.In addition to feeder protection,the device can also be used for transformer and motor protection and control,or for switchgear control alone.The REF542PLUS device has a wide protection setting range and is easy to configure each function block to adapt to various application fields.

2.Main features

Modular design:

REF542PLUS adopts modular design,which is convenient for users to configure and expand according to actual needs.

Real-time multi-function protection and switchgear control:

Provide real-time multi-function protection and switchgear control,including measurement and monitoring of electrical parameters such as current and voltage,as well as circuit breaker opening and closing operations.

Status monitoring and self-diagnosis:

Provides a variety of features to monitor primary equipment and implement self-diagnosis,such as the maximum and average currents within the monitoring cycle,the cumulative value of the breaking current,the operating time,the number of circuit breaker operations,etc.

Powerful communication function:

Equipped with a communication interface,it can communicate with the superior management system(such as the energy management system,the building automation system)to achieve remote monitoring and data acquisition.

Friendly human-machine interface:

Equipped with a large-screen LCD human-machine interface(HMI),which supports multiple language displays,making it convenient for users to operate and monitor.

Easy to install and maintain:

Designed as a compact and easy-to-install structure,it is convenient for users to install and maintain.

III.Application fields

ABB REF542PLUS is widely used in medium-voltage and low-voltage power systems,substations,industrial power systems(such as manufacturing,chemical plants,etc.),wind farms,solar farms,rail transit systems,and urban infrastructure(such as hospitals,schools,commercial buildings,etc.)to protect key equipment from power failures and improve system reliability and stability.

IV.Main technical parameters(example)

AC input:up to 8 AC input channels,current and voltage sensors or traditional transformers can be connected.
