Filtration and blocked

Automatic reactive power compensators of protected or filtration versions are suitable in the indoor version for central and group compensation in the HV networks affected materially by the harmonics generated by non-linear appliances, e.g. frequency converters, controlled and uncontrolled rectifiers, etc. The compensation device also consists of individual steps switched by vacuum contactors. The stage does not comprise only the capacitors, but also the front end (upstream) filter chokes or wave-traps. For this very purpose the capacitors have adequate current and voltage dimensions.
The compensation device can also be delivered with quick discharge of steps, thanks to which dynamic features of the device can be improved materially. In this configuration the device is suitable as replacement of the rotating compensators with less advantage operating features in the applications, where interfering appliances are connected in the network.
