Abstract
In recent years there has been an increase in the availability of on-line condition monitoring devices and systems and of monitoring installations in utility networks. Their installation is judged considering a lot of factors including: general utility strategy, expected value from such an installation, asset and risk management, utility best practices, economic, environmental or regulatory pressures, and will vary from one utility to another. What is the present experience, the value from on-line condition monitoring and what are the opportunities and challenges in future grids and considering modern technologies? The paper intends also to position on-line condition monitoring in life strategies and point to evolution and international activities related to the topic.
Highlights
In recent years there has been an increase in the availability of on-line condition monitoring devices and systems and of monitoring installations in utility networks
The degradation detection point is continuously evolving with technology and knowledge
Increasing efforts have been done to respond to these challenges by advancing diagnosis and monitoring research, by using diagnosis and on-line condition monitoring (OLCM), by having internal utility strategies for asset management or for installing and using OLCM systems
Summary
In recent years there has been an increase in the availability of on-line condition monitoring devices and systems and of monitoring installations in utility networks. Such condition related information can be derived based on few major information pillars, such as: equipment history, e.g. operation and maintenance, information from diagnosis tests performed, information from OLCM systems, expert knowledge and manufacturer’s expertise, Fig. 2.
