Software applications

Energy management with powermanager
Siemens offers the powermanager software application, which is designed for power and
plant monitoring applications. When used in conjunction with SENTRON protection devices
such as 3VA, 3WL, 3VL, and PAC as well as equipment supplied by third parties,
powermanager is a power monitoring system that reduces energy costs and increases the
availability of electrical supply and distribution systems.
powermanager acquires the measured variables that are needed to optimize power
consumption and so reduce costs. These variables not only include energy and power
values, but also electrical parameters such as current, voltage, or power factor. Not only is
this system able to display values, but also to monitor and archive them for later analysis. In
addition, the load monitoring function is capable of monitoring a specified setpoint and
making recommendations as to which loads should be connected and disconnected.
