The robust multi-functional relay test system ARTES RC3 is the robust and universal solution for testing protection relays. Packed in a handy, extremely robust, and resistant hardshell case, the versatile test system is also ideally suited for challenging outdoor use, for example, in the sector of renewable energies. ARTES RC3 makes light work of highly complex test tasks. Three voltage and three current outputs and the built-in control panel allow three-phase tests on static and digital relays also without external PC.
