FOCS DC Current Measurement


ABB's FOCS is a family of high accuracy fibre-optic current

sensors developed for measuring high dc currents. The easy

and flexible use characterizes this technical innovation. Based

on the magneto-optic effect (Faraday effect) in a single-ended

optical fibre around the current conductor, the FOCS can

measure uni- or bidirectional dc currents up to 500 kA with an

accuracy of 0.1 % of the measured value.

The key product features can be described as:

Compact design for fast and easy assembly, installation

and transport

Immune to electromagnetic interferences due to optical

measurement and therefore no need of magnetic centering,

busbar studies or subject to saturation effects which reduce

the accuracy

• High accuracy of 0.1 % of the measured value for precise

plant efficiency calculation

• No special building structure for the protection and

housing of the sensor

• Optical current measurement for galvanic isolation of the

system and low power consumption
