“…Hydrophone based general purpose sensors, piezoelectric accelerometers and broadband transducer-based sensors are used for the measurement of acoustic emissions in 0 to 90 kHz frequency range. Distributed acoustic and temperature sensing systems that use the temperature, strain, and vibration sensitive Rayleigh backscattering technique-based optical fiber yield more accuracy in fault detections by replacing multiple sensors with a single optical fiber sensor [50]. Alternatively, multiple acoustic sensors are integrated with a preamplifier, a high frequency current transducer, and a signal processing unit with a digital acquisition module to form a partial discharge ultrasonic detector to be clamped on the transformer tank [51].…”

The transmission and distribution systems are essential in facilitating power flow from the source multiple loads over large distances with high magnitudes of voltages and currents. Hence, the monitoring and control of various components of these structures are crucial. Traditionally, this was implemented by sensing only the grid current and grid voltage parameters through coils, clamps, or instrument transformers. However, these have bulky structures that restrict them to the substation and have installation and maintenance issues due to their direct contact with high voltage conductors. Currently, the power grid is undergoing various developments e.g., penetration of renewable energy sources, remote control, and automation, bidirectional power flow, etc. These developments call for compact and energy-efficient sensors to sense multiple grid parameters such as the magnetic field data, temperature, humidity, acoustics, etc., to enable real time, wide area monitoring and the predictive maintenance of the power grid. The goal of this paper is to summarize the advancements in sensing technologies on transmission and distribution systems over a decade and to explain their role in the forthcoming expansion of the power grids. This paper aims to outline the current state-of-affairs of sensor technology as well as to fill research gaps by exploring their limitations.

“…The implementation of this method relies upon the fibre‐optic cable which is within the cable structure. In this method, highly coherent laser light is sent into fibre‐optic cable and the response of the system's sensor to the acoustic impulse produced at the fault location locates the site of the impulse signal [74].…”

Power cables are integral to modern urban power transmission and distribution systems. For power cable asset managers worldwide, a major challenge is how to manage effectively the expensive and vast network of cables, many of which are approaching, or have past, their design life. This study provides an in-depth review of recent research and development in cable failure analysis, condition monitoring and diagnosis, life assessment methods, fault location, and optimisation of maintenance and replacement strategies. These topics are essential to cable life cycle management (LCM), which aims to maximise the operational value of cable assets and is now being implemented in many power utility companies. The review expands on material presented at the 2015 JiCable conference and incorporates other recent publications. The review concludes that the full potential of cable condition monitoring, condition and life assessment has not fully realised. It is proposed that a combination of physics-based life modelling and statistical approaches, giving consideration to practical condition monitoring results and insulation response to in-service stress factors and short term stresses, such as water ingress, mechanical damage and imperfections left from manufacturing and installation processes, will be key to success in improved LCM of the vast amount of cable assets around the world.
