摘要：A transformer arrangement comprising a transformer having a neutral andformed as a symmetrical transformer, in particular a cage transformer and having areactor coil connected to the neutral of the transformer is provided. The transformer canbe of any type having a neutral such as a Y-n/Y-n, Z-n/Z-n, Y-n/Z-n or a Z-n/Y-ntransformer. By providing a transformer having symmetrical phases connected to areactor coil a transformer arrangement having less weight is obtained. The lower weightis obtained because in comparison to using an E core for the transformer all phases willbe symmetrical so that if a ground fault occurs in one of then phases there is no need forany compensatory windings regardless of which phase suffers the ground fault.
