Fiber optic sensors are installed during transformer manufacturing for maximum reliability. Reliable real-time temperature tracking leads to improved condition based monitoring, helping utilities optimize performance. The fiber sensor is. Power transformers silently bear the weight of ensuring that electricity flows around the clock, day and night, behind the scenes of every city skyline, industrial park, and railway system. But what if a “silent failure” begins to form deep within one of these transformers, where no standard sensor. Fiber optic temperature sensing technology has revolutionized the approach to transformer temperature monitoring, providing direct, real-time measurement of actual winding hotspot temperatures rather than approximations based on oil temperatures and thermal models. The technology used leverages fiber-optic sensors to provide real-time and accurate temperature measurements. This technology is immune to all forms of electromagnetic interference (EMI) and is capable of functioning safely and accurately inside a high voltage power transformer.
