Three phase space saving 5 limb line choke - CNW 915
When using regenerative converters, chokes are used in order to obtain a clean sinusoidal current. Depending on the type of inverter, so-called common-mode disturbances can occur, which thermally load the choke and lead to leakage of the magnetic field, which can significantly affect metal components in the vicinity. An additional unwound limb, ensures that the choke can always transfer and attenuate these interferences, until they can be discharged to earth.
REO line chokes series 900 CNW solve these problems in an exceptional way, in addition they are space-saving, the production and material costs are lower and thus more cost effective and they are considerably lighter than a solution with, for example, three separate single-chokes.
Furthermore, the line choke limits the mains disturbances occurring as current peaks and voltage drops in the network. Such disturbances can affect electrical systems and are caused by switching operations or earth faults. For this, REO line chokes make an important contribution to improve the electromagnetic compatibility (EMC) of the entire assembly.
