“…In order to perform predictive maintenance of power equipment and to withdraw or repair any defective units before failure, IR-thermography are used for overhead lines [7][8], transformers [9][10], rotating machines [11][12]. The working principle is based upon photon detection of the infrared radiation emitted by the warm bodies in the wavelength range of 2-15 µm.…”

This paper presents a review on condition assessment of some of the most critical components in the power grid today, such as transformers, rotating machines and cables and their accessories. The main purpose is to identify methods that can be applicable for high voltage equipment for subsea use. The question addressed is what diagnostic tools should be used to detect apparatuses with a high probability of failure during service.It is shown that today, only distributed temperature sensing systems are used for subsea applications. At the same time, the majority of condition assessment techniques used onshore can be adjusted for subsea use, particularly methods applicable for on-line monitoring.

“…The first challenge of this work is to define the components of multispectral vision system for the acquisition. Pinto [7] presents a mobile robot for power substation hot spot monitoring. His paper proposes a single infrared camera unit connected to a robot which moves along the substation thought a steel cable inside the substation.…”

Thermography is a technique widely used for inspection of electrical equipment's operating conditions. However, its operation, predominantly manual, hampers more reliable diagnosis of component's abnormality indications. This paper presents a straightforward hybrid stereo vision configuration for autonomous monitoring systems that uses images visible and infrared spectrum to identify, characterize and extract regions of interest for increasing metrological quality of thermal measurements. Experimental results show that it is a viable and approach in asset management systems.

Condition assessments for power transmission line infrastructure and conductors are essential to maintain a reliable and efficient system. LineScout is a high-performance robot designed to undertake detailed, comprehensive inspections of transmission lines, which contributes to maintaining the integrity of equipment and the safety of inspection crews. This paper outlines Hydro-Québec's LineScout Technology, describing briefly the main systems and key design issues and discussing the technology's impact and benefits on power transmission line inspection and maintenance practices. The paper then focuses on field results gathered over the past 2 years with LineScout Technology. Very important lessons were learned from more than 20 field deployments of the robot on live transmission lines. An appreciable amount of significant feedback came from these field visits and was decisive in improving the technology. Specifically, transportation and installation methods and onboard energy management strategy are presented. Also discussed, for the first time, is a simplified wheel contact radius estimate, useful for improving the wheel odometer readings. Finally, one field deployment on a large water crossing transmission line is presented in detail. The paper discusses the importance of the work done and of newly implemented features in terms of the quality and efficiency of inspections, the reliability of systems, and the safe operation of the technology.
