Fiber-Optics-Based Fault Detection in Power Systems
This article presents a fiber-optics-based sensing network for fault detection in power systems. This scheme is considered secure and immune from interferences. A passive rugged fiber-Bragg-grating-based sensors are present a each of the monitoring locations. magnetostrictive transducers are used in the place of CT or PT for the purpose of converting the magnetically induced currents into optical signals. The temperature drift in these sensors can be easily compensated for. An increased fault current at a certain location causes a surge in the magnetic field. This surge occurs in a particular frequency band. A broadband light source at a substation scans the change in reflected optical power in this particular unique frequency band. Only the current information is required for detecting the fault in the case of radial and networked systems with various pole structures and line configurations.

magnetostriction based fiber-optics current sensors (FOCSs) is used in the present sensors to convert the magnetic field from a current into mechanical strain on a FBG. rapid signal transmission is possible as these passive FOCSs do not need power source and they modulate optical carriers directly. The fault signals from various FOCSs can co-exist in a single strand of optical fiber
cable as these FBG in each FOCS reflects power at a unique wavelength band.
Fiber-Optical Current Sensors
They have many advantages which include:
-immunity to EMI,
- high dynamic range
- compact design
They are installed at installed at overhead power lines or where the underground cables are available at surface.
