In this presentation, Alan Ross, President of the Electrical Power Reliability Alliance (EPRA), will address the four high-voltage asset classes that lead to the greatest risk of failure, power quality issues and ultimately to overall decreases in OEE and AU at a time when we can least afford these risks.
This presentation will explain how maintenance of electrical equipment directly impacts the safety of electrical workers as well as giving an inside look at some of the changes to be expected in the coming Standard for Electrical Equipment Maintenance.
Since the beginning of time, human beings have survived and evolved through the use of tools. Tool usage is the basis for both ancient and modern engineering advances.
Reliability engineering is about predicting failures and providing ground for decision-making related to preventive maintenance optimization (PMO), lifecycle costing, spare parts forecasting, and reliability, availability and maintainability (RAM) modeling. Different tools are available to the reliability engineer for such levels of predictions. The benefit of these tools comes from proper planning and management plans to cope with future issues.

The NFPA 70E provides the requirements for protecting employees when exposed to electrical hazards suck as shock and arc flash. However, is your company's maintenance practice actually elevating the severity of a potential arc flash event?
Hindsight is the ability to understand an event or situation only after it has happened. How many times have you witnessed an asset failure and realized during the root cause analysis (RCA) investigation that there were indicators that a catastrophic failure was about to occur? Have we, as maintenance reliability practitioners, become desensitized in their ability to recognize the telltale signs of a failing asset? Is this being accepted as the new normal?
TRC-2018 Learning Zone 42:32
by Tim Rohrer, Exiscan
NFPA 70E and CSA Z462 are (arguably) the two most influential electrical safety standards in the world. The changes contained in the recent 2018 revisions of these harmonized standards have a direct impact on Electrical Preventive Maintenance (EPdM) practices, and likely have a direct impact on your facility(s). Likewise, the standard used throughout the world for arc flash hazard calculation (IEEE 1584) is in the final stages of revisions based on recent research on the subject. This presentation will highlight some of the changes that carry the biggest impact for Electrical Preventive Maintenance, and will answer the questions:
What changes to electrical safety standards should I be aware of?
What impact do those changes have on the EPdM work practices and design principles at my facility(s)?
What steps can I take upon returning to improve the worker safety and regulatory compliance at my facility(s)?
PKN ORLEN operates six refineries (daily crude oil processing 728,000 barrels) and the region’s largest network of service stations located in Poland, Czech Republic, Germany and Lithuania. Crude oil is processed into gasolines, diesel oil, fuel oil and aviation fuel. PKN ORLEN is also a leading producer of petrochemicals, with its products used as basic feedstocks by a large number of chemical companies.
Plant and refinery problems require accurate measurements to assess plant productivity and reliability. In fact, as management guru Peter Drucker stated, “You can’t manage what you can’t measure,” forms the basis to many real-world problems, from engineering optimization studies to troubleshooting plant machinery and equipment. Drucker’s statement also alludes to the fact that you cannot know whether or not you are successful unless success is defined and tracked.
Problems with reliability appeared with the beginning of human activity. However, the ways of solving these problems were different and they were changing with growing complexity of technical systems. The retrospective view shows that the way of solving reliability problems depends on the ratio between the complexity of the system and the ability of people to obtain information about the system and its elements.
A new ASTM International subcommittee on reliability (E11.40) is developing a standard (WK58249, Guide for Reliability) that will support reliability and risk analysis. The new subcommittee is part of ASTM International’s committee on quality and statistics (E11).
Many reliability engineers throughout history have had concerns with the reliability of the repairable system. Several researchers have presented a few calculation or estimation techniques to achieve repairable system reliability. This article explains the mean cumulative function (MCF) as a powerful and easy technique to estimate and monitor repairable system reliability.
IMC-2016 RAP Talk - 17:57
by Ramesh Gulati, Jacobs
According to Ramesh Gulati, designing for reliability (DfR) is the right approach to build reliability in assets. Not sure what DfR is? In this RAP Talk from IMC-2016, Gulati presents a comprehensive overview on the topic and how it will reduce operations & maintenance costs by a lot. Throughout the presentation, he stresses that this is a journey and requires a different kind of culture.
Belt drives are often considered the fuse of the power transmission drive path, which can be an advantage for belt drives. In that line of thinking, not much thought is given to the impact on overall equipment reliability with respect to the belt drives connecting driver and machine.
