 Fiber Optic Current Sensors (FOCS) are resistant to affects from magnetic field interferences. Consequently, they are ideal for the measurement of electrical currents and high voltages in electrical power substations. FOCS target to replace existing Hall effect solutions which tend to be bulky and heavy. In fact those used for high-end currents can weigh as much as 2000 kg compared to FOCS sensing heads which weigh less than 15kg. FOCS have the advantage of simplified installation, increased accuracy and negligible power consumption. The sensing head usually contains a semiconductor light source module, typically a Superluminescent Light Emitting Diodes (SLEDs) which are robust, operate in extended temperature ranges, and have verified lifetimes, and are cost effective. |
