Infrared thermography, ultrasonic noise analysis, partial discharge detection, dissolved gas analysis, vibration analysis - all are very high tech and necessary to determine the health of a transformer fleet. Although high tech is needed, it must be coupled with a good dose of common sense. To determine the condition of each critical transformer on a system, a process must be adopted to provide enough data and information to make a decision to repair, replace, or continue to trend a detected condition.
Whether attempting to bring a specific department or an entire organization to a new level of expertise, certain checks and balances must be in place. Better maintenance practices usually do not evolve into something better on their own, unfortunately.
In the Dec/Jan 2013 issue of Uptime magazine, an article by Tarek Atout stated that, “You Deserve Your 3‘Rights’.” A major point of the article was, “the main bad factor that will cause disturbance to all maintenance activities is being out of stock of a critical item.” Mr. Atout goes on to list many of the efficiencies lost by maintenance and the waste that occurs because of an unreliable stores situation that is not integrated with the correct computerized maintenance management system (CMMS).
Implementing a predictive maintenance (PdM) program can be tough in today's manufacturing world. Despite proven successes of many programs, numerous companies that have been operating the same way for over 50 years don't know where to start. Understanding where to start and where to focus in the future is critical. The intention of this article is to give some insight into starting up and sustaining an effective program using today's technology and devices.
Polar vortices across the United States, floods across Great Britain, hurricanes in the Philippines…what is happening with the weather these days? There is no doubt weather patterns are changing, with nine of the 10 warmest years on record occurring in the last decade. Experts say too much heat remains in the earth’s atmosphere and oceans, causing a weakening of the Gulf Stream and changing weather patterns. The main culprits for this additional heat are greenhouse gases, such as carbon dioxide, methane gas and nitrous oxide. Since late 2013, scientists finally had the data to link climate change to human activity. As the global population increases, so too has human activity and the resultant greenhouse gases.
Manufacturing and industrial facilities rely on rotating assets, such as pumps, compressors, fans, motors and turbines. Maintaining these critical assets is crucial to uptime and performance. It is estimated that less than 20 percent of these critical assets are proactively monitored to detect problems and determine their mechanical health.
To manage the operations of a facility effectively and efficiently, certain fundamentals need to be in place. One of those fundamentals is information. Information about assets, the data to perform maintenance and information to establish a reliability regime are essential for any good management of change (MOC) process.
