In order to save costs, it can be often used a two-phase isolated voltage transformer, which are connected to a
phase-to-phase voltage. In this case the phase sequence supervision is inactive and reliability restrictions when
connecting to the dead busbar must be accepted. Full two-channel redundancy is ensured.
