“…While this shows it is possible to detect PD in cables, the current state of the technology is impractical as it is only sensitive to high levels of discharge and, therefore, cannot provide early warning of defects. The authors of [178] investigated whether PD can lead to detectable temperature changes in the cable, allowing indirect PD measurement. A cable joint with a knife scratch defect was placed in a constant temperature chamber and results showed a temperature variation of 0.2 • caused by a partial discharge of 300 pC.…”

The high-voltage (HV) assets in the existing power transmission network will experience increased electrical, thermal, environmental and mechanical stresses and, therefore, robust condition monitoring is critical for power system reliability planning. Fibre Bragg grating (FBG) sensors offer a promising technology in HV applications due to their immunity to electromagnetic interference and multiplexing capability. This paper reviews the current technology readiness levels of FBG sensors for condition monitoring of transformers, transmission lines, towers, overhead insulators and power cables, with the aim of stimulating further development and deployment of fibre-based HV asset management systems. Currently, there are several reported cases of FBG sensors used for condition monitoring of HV assets in the field, proving their feasibility for long-term use in the power grid. The review shows that FBG technology is versatile and can facilitate multi-parameter measurements, which will standardise the demodulation equipment and reduce challenges with integrating different sensing technologies.

“…Another work is presented by Kim et al (2022), which deals with an experimental study in which several FBG networks are used to detect vibro-acoustic signals from leaking water pipes using an interrogation system with 3 kHz sampling capability. Similarly, Tozzetti et al (2021), showed an experimental study about dynamic deformation measurements in gasoline direct injectors where FBGs were placed on the surface of a valve body along the axial direction, this employing an interrogation system with measurement capability up to 240 MHz.…”

“…of the most outstanding developments is that of Kim et al (2022), where they conceived a spectrometer-type interrogation system where the reflected wavelengths feed a photodiode array module through a fiber optic circulator to demodulate the Bragg wavelength. Buck et al (2012), on the other hand, designed a highly integrated interrogator based on an ordered waveguide grating, specially constructed for the acquisition of dynamic structural loads.…”

Recently it has been reported the use of non-invasive methods for the identification and monitoring of vibrational parameters in rotodynamic systems, such as aircraft engines, which require the implementation of innovative detection systems, such as fiber optic sensors, which overcome deficiencies of adaptability to adverse environments such as intense magnetic fields and the impossibility of performing a distributed detection of vibrations, limitations present in the sensors conventionally based on capacitive or piezoelectric principles. Therefore, in the present study, through the use of an experimental platform for dynamic analysis, the best proposal of an instrumental system based on fiber optic sensors with Bragg gratings was selected for its use in vibrational measurement and analysis, through the theoretical study of the different approaches to vibrational analysis using fiber optic sensors with Bragg gratings. The analysis of the results of the study presents a justification of the type of instrumental proposal selected from the characteristics provided by the experimental platform. In addition, the experimental proposal will be implemented in the future and may contribute to the development of other vibrational studies.

“…In [16], the authors demonstrated this technique in the laboratory, using discrete sensors; in [17], it was demonstrated in the field using an FBG array sensor; in [18], a new packaged FBG sensor was developed for underground cable temperature monitoring; and in [19], FBG sensors were used to monitor temperature power cable joints in underground utility tunnels. In [20][21][22], the authors studied the FBG as a PD sensor for cable applications. In [23], the authors developed an optical voltage transformer based on FBG-PZT for power quality measurements, and in [24], FBG sensors were studied for enhanced microgrid performance.…”

This work presents a multi-parameter optical fiber monitoring solution applied to an underground power distribution network. The monitoring system demonstrated herein uses Fiber Bragg Grating (FBG) sensors to measure multiple parameters, such as the distributed temperature of the power cable, external temperature and current of the transformers, liquid level, and intrusion in the underground manholes. To monitor partial discharges of cable connections, we used sensors that detect radio frequency signals. The system was characterized in the laboratory and tested in underground distribution networks. We present here the technical details of the laboratory characterization, system installation, and the results of 6 months of network monitoring. The data obtained for temperature sensors in the field tests show a thermal behavior depending on the day/night cycle and the season. The temperature levels measured on the conductors indicated that in high-temperature periods, the maximum current specified for the conductor must be reduced, according to the applied Brazilian standards. The other sensors detected other important events in the distribution network. All the sensors demonstrated their functionality and robustness in the distribution network, and the monitored data will allow the electric power system to have a safe operation, with optimized capacity and operating within tolerated electrical and thermal limits.
