Overview
Feeder protection and interconnection of decentralized energy resources
The MCA4 is a precise and reliable protection, control and monitoring relay for feeder, grid and generator applications. The latest generation series from Woodward (formerly SEG), the MCA4 incorporates all the ANSI and IEC concepts to comply with ever changing grid interconnection requirements. Flexibility in hardware, software, application, user interface and communications makes the MCA4 adaptable to requirements today and in the future. The protection functions of the MCA4 have been adapted to comply with the requirements of the VDE-AR-N-4110/4120:2018.
The parameterizing and analyzing software Smart view is usable for eachHighPROTEC device and free of charge.
MCA4 is the ideal directional feeder protection for industrial and utility distribution networks. Integrated interconnection / grid code package. Large control capacity for switchgear. Very large protection package (reclosing, load shedding, load restoration, demand management, monitoring functions,)
