    Abstract: A fiber-optic current sensor includes a measuring unit having a light source and a light detector, and a sensing head having a sensing fiber wound around a conductor and a retarder connected to the sensing fiber. The scale factor as a function of current of the fiber-optic current sensor is described by the product of two scaling functions fe′ and fs′ for the measuring unit and the sensing head, respectively. The data describing the scaling functions fe′, fs′ is stored in a memory of the measuring unit, while the data describing the scaling function fs′ is also stored in a memory of the sensing head. Providing two such memory devices allows to store the scaling functions fe′ and fs′ separately, thereby turning the control unit as well as the sensor head into easily replaceable modules.

According to one method, when a fault condition occurs in a load being supplied by a power generator, a number of pole slips expected to occur in the generator due to the fault before resynchronization is estimated. It is determined whether the estimated number of pole slips exceeds a threshold. An offline or online status of the generator is controlled based on the determination as to whether the estimated number of pole slips exceeds the threshold.
