SUMMARYAsset management is one of the key components in a transforming electric power industry. Electric power industry is undergoing significant changes because of technical, socio-economical and environmental developments. Also, because of restructuring and deregulation, the focus has been on transmission and distribution assets that include transmission lines, power transformers, protection devices, substation equipment and support structures. This study aims to provide a detailed exposure to asset management classification, various interesting maintenance methods and theories developed. The work encompasses the issue of data management in recent years. Because of the use of various smart metering devices, large amounts of information are being collected. The advent of data-mining techniques has changed the asset management scenario, and it has been covered in this survey paper. In the end, it also discusses various risk assessment techniques in asset management developed and used for academic research and industries. It is accompanied with survey results from pan-European Transmission System Operator (TSOs) on various aspects in asset management.

“…Study reveals about substantial research on power transformers in various literature about health monitoring, ageing, and oil indicators [110][111][112][113][114][115]. Similarly, studies have been carried out for overhead lines [115][116][117][118], underground cables [115,119,120], and circuit breakers [115,[121][122][123][124]. Yoon and Teo [125] presented a real-life case study on AM in Singapore though it focused on underground grids.…”

et al. 2016

In the planning and operation of power systems, actions are taken in different processes and time-horizons. The purpose of these actions is to secure a high reliability level. Although the three main processes (grid development, asset management, and system operation) are described in literature, there has been no explicit study on the time-horizons (long-term, mid-term, and short-term) and actual time-scale (decades, years, months, etc.) that these processes focus on. This study aims at making a review of the various activities performed by transmission system operators while reviewing the concept of each time-horizon and methodologies developed in literature. As decisions taken in different time-horizons can influence each other, the interactions and overlapping are discussed.

“…Study reveals about substantial research on power transformers in various literatures about health monitoring, ageing, and oil-indicators [38]- [43]. Similarly, studies have been carried out for overhead lines [43]- [46], underground cables [43][47] [48] and circuit breakers [43][49]- [51]. A real time case study on asset management in Singapore was conducted by Yoon and Teo [52], though it focused more on underground grid.…”

“…2. Leaving aside IT and HMI in asset management, various computational models and optimization techniques have been developed for maintenance, refurbishment, ageing and monitoring techniques in asset management, like state diagram [55], fuzzy technique [34][42] [56], neural networks [39], PSO [35], linear programming [46][57], branch and bound technique [58] and other optimization techniques [36][59] [60]. Anders et al [61] combined engineering and financial aspects of asset management into software tool called Risk-Based Asset Management (Ri-BAM).…”

et al. 2015

Abstract-This paper presents a literature study on asset management in electrical power transmission and distribution system. Due to restructure and deregulation of electric power industry in recent times, the focus has been on transmission and distribution assets that include transmission lines, transformers, power plants, substations and support structures. The study aims to provide a first of its kind exposure to asset management classification, various interesting maintenance methods and theories developed in last two decades. In the end, it also discusses various risk assessment techniques in asset management developed and used for academic research and industries.Index Terms--Bibliography review, asset management, mid-term transmission planning, maintenance planning, risk assessment.
