A TRANSFORMER ARRANGEMENT |
摘要 |
<p>A transformer arrangement comprising a transformer having a neutral and formed as a symmetrical transformer, in particular a cage transformer and having a reactor coil connected to the neutral of the transformer is provided. The transformer can be 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-n transformer. By providing a transformer having symmetrical phases connected to a reactor coil a transformer arrangement having less weight is obtained. The lower weight is obtained because in comparison to using an E core for the transformer all phases will be symmetrical so that if a ground fault occurs in one of then phases there is no need for any compensatory windings regardless of which phase suffers the ground fault.</p> |
