The REF542PLUS is a digital protective relay used for protection and monitoring in power systems. It is based on the 100BaseTx standard, uses unshielded twisted pair and RJ-45 connectors, and has a maximum length of 100 meters. The device also supports 100BaseTx Ethernet, providing dual Universal Serial bus (USB) connectivity to the front panel. In addition, the REF542PLUS features an SVGA port and is supported by an Intel Graphics & Memory Control Controller Hub (GMCH) chip with 4Mbyte video DRAM that supports VESA high resolution and extended video modes.
Technical note: The REF542PLUS feeder terminal can be used in a variety of different medium voltage applications
The ref542 + multifunctional protection and switchgear control unit processes multiple data to protect, control and monitor switch panels: GIS panel Type ZX and AIS panel type ZS1. All inside the master controller
Some serial ports have available data. Application of Modbus RTU board in multi-function protection
The switchgear control unit REF 542plus allows one or two control systems to be connected. In the case of both control systems, the same commands and monitoring can be sent and received using Modbus RTU
Data communication protocol. The ASCI mode is unavailable.
The REF 542plus feeder terminal is a compact digital spacing control technology solution. It can be used in a variety of different medium voltage applications, such as feeder protection, voltage protection and motor protection.
Like its predecessor REF 542-, the feeder terminal REF 542plus integrates measurement, monitoring, protection, control and self-diagnosis in a single component. With its integrated communication protocol, the REF 542plus can be lightweight
Loose integration into any substation automation system from ABB or a third party.
These new generation devices offer excellent flexibility and scalability compared to more traditional methods, enabling smart and clean solutions. The software solution allows you to work in all ABB -- times
REF 542plus is used in gas and gas insulated switchgear solutions.
