DEIF's phase sequence meters are applied to check and indicate correct and incorrect connection of the phases plus phase breakage of a shore connection.
A check of the phase sequence is required for connecting equipment to a new voltage source, e.g. when changing from the mains supply of a vessel to the mains at harbour.
The indicator can also be applied for alarm indication on phase breakage.
