The ABB REF 542plus multi-function protection and switch control device is a device that integrates protection, control, measurement, communication and monitoring functions, mainly for the protection and monitoring of medium and low voltage power systems. Here is a detailed description of the device:

Main feature

Multi-function integration:

REF 542plus integrates multiple functions such as protection, control, measurement, communication and monitoring, so that one unit can perform multiple tasks and improve the integration and efficiency of the system.

Programmable environment:

With a programmable environment, the REF 542plus offers a high degree of flexibility and extensibility, enabling the implementation of almost all secondary solutions, even those that are not possible with traditional methods.

Optimization design:

Optimized design for air or gas insulated medium voltage switchgear ensures efficient operation of equipment in specific environments.

Multiple protection functions:

Through software configuration, REF 542plus can realize up to 24 protection functions, such as short circuit, overload, ground fault, etc., to provide comprehensive protection for the power system.

Human Machine Interface (HMI) :

REF 542plus has a graphical man-machine interface and supports Chinese display, making the operation more intuitive and convenient. The HMI is designed separately from the host unit to provide maximum installation flexibility.

Communication Protocol:

Support for a variety of communication protocols, including IEC61850, enabling devices to seamlessly integrate and communicate with other devices, systems, or monitoring systems.

Operation mode:

Local control mode, remote control mode, and local and remote control mode are available to meet users' operation requirements in different scenarios.

Certification and Qualification:

REF 542plus has a variety of certification qualifications, and has many years of application performance at home and abroad, proving its reliability and stability.

Application field

Distribution network protection:

The REF 542plus can be used to protect medium and low voltage distribution systems, ensuring rapid removal of fault areas in case of failure and improving system reliability.

Substation application:

In substations, REF 542plus can be used to protect transformers, switchgear and other critical equipment, ensuring the safe and stable operation of substations.

Product composition

The REF 542plus consists of a separate host and human machine interface (HMI) connected by shielded twisted pair cables. The host includes a power board, motherboard, analog and switching input and output, and some other expansion function cards. The HMI has a separate power supply and can be installed on the low-voltage chamber door panel or in another location near the main engine.

Additional function

REF 542plus also supports remote monitoring, power quality monitoring, event recording and alarm, equipment health care and diagnosis and other functions, providing users with a comprehensive power system solution.

In summary, the ABB REF 542plus multi-function protection and switch control device is a comprehensive, reliable and flexible industrial automation equipment, which is widely used in the protection and monitoring of medium and low voltage power systems.
