Applications
The static VAR compensator controller is a device with micro-processor core. It monitors voltages and currents of a three-phase system, and features 6 kinds of instantaneous and full compensation strategies and 12 kinds of switching programs. The control can also be adjusted and it will remember the changes. Our controller can be used for auto controlling of reactive power compensations in electrical systems of 45Hz-65Hz under 0.4KV.
