PARMA RAS VAF-A(M2) is a three-phase voltampere-phase meter, which also functions as a recorder of emergency and normal signals. It is designed to measure parameters of electrical networks, such as voltage, current, phase shift angle, and to determine phase rotation. In addition, the device can be used to record emergency and normal operating modes.
