Fiber optic current sensors offer several advantages over traditional electrical sensors, including immunity to electromagnetic interference, the ability to function in extreme environments, and high accuracy. They also provide non-invasive operation, which eliminates the risk of. Following are the drawbacks of using Fiber Optic Sensors: High Cost: They are very expensive. Complex Detection Systems: Detection systems can be complex. Requires Training: Users may be unfamiliar with the technology, requiring basic training before use. These advantages are essentially related to the optical fiber properties, i., small, lightweight, resistant to high temperatures and pressure, electromagnetically passive, among others.
