“…Since vibration or ultrasonic signal will cause the deformation of FBG, and signal intensity closely influences the shift of Bragg wavelength (λ B ), the vibration [106,107] and ultrasonic produced by PD [108][109][110][111][112][113][114][115][116][117][118] can be detected by FBG-based sensors.…”

“…Dreyer et al [107] presented the multiplexed FBG‐based transducers for simultaneously monitoring temperature and vibration, and experiments in the power plant showed excellent detection capability of mechanical vibration (2 Hz) and electromagnetic vibration (120 Hz) in a 370‐MVA hydroelectric generator. Sarkar et al [108, 109] developed an FBG sensor for online detection of PD by analysing the shift in Bragg wavelength. Later in [110] they proposed an intensity modulated FBG‐based PD sensor to simplify the system, requiring neither FBG analyser nor narrow‐band tunable laser source, but the sensitivity was insufficient.…”

Optical fibre sensing technology is a powerful method for long-term reliable sensing in harsh environments, which means it is particularly suitable for the detection of electrical equipment characteristic state parameters, including characteristic gases, abnormal vibration, ultrasonic produced by partial discharge, and abnormal temperature rise. This paper reviews several individual optical fibre sensors for different state parameters detection, discusses the advantages, limitations and possible improvement methods, and finally presents the most promising optical fibre sensor for each state parameter.

Acoustic measurement is the most widely used non-electric method to detect partial discharge (PD) signals by detect the ultrasonic waves arisen from partial discharge. To solve the shortages of low sensitivity and susceptibility to interferences, a gold diaphragm based Fabry-Perot interferometer ultrasonic sensor is proposed and experimentally demonstrated. Its high acoustic sensitivity and directional insensitivity shows great capability for PD detection and localization. Experimental results illustrate a well acoustic response from 20 kHz to 150 kHz when standard ultrasonic signals applied. The frequency range covers the acoustic frequencies derived from PD process. The ultrasonic signals from a discharge source is measured by the proposed fiber optic sensor with difference distances and incident angles. The output shows an attenuation of 1.32 dB/m and the sensor can detect weak signals as far as 3 m. The directional deviation coefficients are less than 10% for each measuring distance which exhibits directional independence. Two localization techniques with a sensor array (four sensors) are proposed and simulations are carried out to verify them feasible. The fiber-optic ultrasonic sensor may have a great potential in stability maintenance of electrical power systems due to its low cost, compact structure, environmentally robustness and simple manufacturing.
