OCTC/DETC

DEETAP® DU

Off-circuit tap-changers (OCTC) are used for voltage adjustment in oil-immersed transformers. In contrast to on-load tap-changers, off-circuit tap-changers can operate only when the transformer is deenergized.

COMTAP® ARS

An Advanced Retard Switch (referred: ARS) is used to reverse the polarity of a winding during transformer operation. The COMTAP® ARS has two basic operating positions. With an ARS application the through-current of a current path is commutated to another current path of the same potential. The contact system is... view more
