ABB REF542PLUS

The ABB REF542PLUS module is a powerful digital protective relay that is widely used in the protection and monitoring of power systems. It has a variety of protection functions that monitor the state of the power system and take the necessary measures to protect power equipment from overcurrent, sh

ort circuits and other power failures. The REF542PLUS module is not only protective, but also integrates control, measu

rement, communication and monitoring functions, making it an integral part of the power system.12

The REF542PLUS module’s control display panel provides a user interface for configuring, monitoring and operating relay functions. At the same time, the module supports a variety of communication protocols, such as IEC61850, which makes it possible to exchange and integrate data with other devices or systems2.
