MS 156 amplifier units can be used in combination with any CMC test set or in conjunction with digital real time power system network simulators. The outputs are galvanically separated from the inputs as well as from ground and are used independently or in addition to those of the CMC test sets. The connection to a CMC test set is made by a control cable at the back of the units.
Used for tests requiring
• six independent voltage phases (e.g. for testing synchronizing devices with two independent three-phase voltage systems)
• more current channels than provided by the CMC test sets
