3. General
REF 542plus is a Switchgear Multifunction Protection and Switchgear Control Unit
and it is the further development of the former REF 542 multifunctional unit. Like
its predecessor, it features the following functions:
*
Protection
*
Measurement
*
Control
*
Monitoring and self diagnosis
*
Communication
All above-mentioned and also power quality functions are integrated into a
programmable environment. The exceptional flexibility and scalability of this new
generation device lead to a smart solution where the traditional approach would be
ineffective and expensive.
The following figures Fig. 3.-1 and Fig. 3.-2 show examples of the REF 542plus
installation in several switchgears.
