Condition monitoring - fault detection and diagnosis

The use of condition monitoring can be seen as a development from preventive maintenance, which itself developed from break down maintenance. Modern process requirements demand greater availability and reliability of machines which can only be provided through accurate monitoring of machine health. This allows maintenance personnel to determine the best possible course of action based on knowledge available from condition monitoring (Mahamad, 2010). Condition monitoring has found greater favour in maintenance circles based on savings and system simplification provided by it. Not only does condition monitoring allow the operator to make correct and on time maintenance decisions, it also allows a reduction in maintenance costs. The improvements offered in terms of greater system availability also provide direct financial benefit to processes that cannot afford to have significant maintenance delays. Overall a sizable reduction in maintenance costs and direct fiscal benefits offered by more reliable machines has pushed condition monitoring to the forefront of maintenance globally (Fuqing, 2011). ...

Managing of Energy Assets (Monitoring Transformer Performance)
There are two main categories of transformers, which include dry type and liquid filled transformers. In this paper, we will prepare a proposal for oil-filled transformers at substations, which are one of the main types of liquid filled transformers. Oil filled transformers make use of cellulose paper and mineral based oil in their insulation systems. This combination of cellulose paper and oil is very good for the working of transformers because they provide remarkable dielectric and thermal properties at a low cost. About this combination, Dickinson (2009) states, “So popular and effective…

Condition based maintenance optimization: Solution implementation in practice and Condition based maintenance methods
The prime objective is to maximise the uptime of machines and other equipment. Maintenance techniques have evolved over the years and have been adapted to various situations. Some programs are customised to maximise uptime. Others are designed to minimise the cost of spares while others are optimised to minimise human interference. The term maintenance is taken as the combination of technical, administrative and managerial actions that are taken throughout the lifecycle of equipment and machines. Broadly maintenance can be classified into two categories which are corrective maintenance and…

Machinery parts composed of bearings are primarily aimed at minimising friction and abrasion. However, due to various reasons like general wear and tear, heating, cracking, rapid temperature change, etc., a bearing may malfunction. This malfunctioning generates repeated discrepancies and mechanistic disruptions, which might be endured by the machinery in the early stages. The problems due to increased frictions inside the bearing parts are usually acoustic in nature, and impact-echo method of vibration monitoring becomes important in detecting them (Sandalone and Street, 1998). If defects of…

The second part addresses issues worth consideration when applying Breaker Failure Protection and lastly, advances towards breaker Failure Protection. Using algorithms significantly enhance the numerical BF protection. Introduction Contingency analysis remains to be one of the great tasks that face protection engineers. The reason to this is due to the fact that a Protection Engineer has to focus on Murphy’s Law and Ohms Law concurrently. The design for PRS plays a key role in detecting any fault that happens on the power system and the possibilities of eruption of any fault in the…

In recent years, there has been a growing trend to introduce more intelligent methods in order to deal with condition monitoring and fault classification for machines (Mills, 2010). The realm of artificial intelligence and its application may be infant as yet but still involves the application of various methods and techniques for achieving desired ends. The current research will look into various artificial intelligence methods that have been applied to the condition monitoring and fault diagnosis for a reciprocating air compressor based on emerging and already developed methods and…

Fault Detection and Diagnosis using Principal Component Analysis of Vibration Data from a Reciprocating Compressor
PCA has been employed with genetic algorithms (GA) in order to reduce data dimensionality for use in fault diagnosis of induction motors. PCA was employed to remove relative features, after which GA was employed to select the irrelative features and to optimise the ANN (Yang, Han and Yin, 2006). Fault detection and diagnosis of plant subsystems have also been attempted using PCA. Normal plant operation decomposed through PCA was compared to faulty operation data through PCA decomposition to create thresholds for taking corrective actions. Real time monitoring of plant operation data was…
