Engineering ethics presentations typically involve a recital of the regulations and laws pertaining to the engineering profession (usually read directly from an overcrowded screen full of text). Not only do these lectures bore me, but it may actually be unethical for me to claim credit for attending these mind-numbing presentations. As a registered professional engineer, I am already required to have a “working knowledge” of the applicable rules and laws. In 2018, I began researching engineering rule violations and ethics infractions to present to engineering colleagues around the world. These case studies offer constructive insights to guide engineers toward the ethical high ground. And - you will not need coffee to stay awake.Full Bio
Good power quality is essential for electrical loads to operate efficiently and reliably. Problems resulting from poor power quality cost the industry upwards of $30-40 billion annually in the US market. Of those costs, 30% is due to the negative effects associated with surges and switching transients.The surges primarily come into the facility in two ways, external (Utility switching & Lightning) and internal (switching transients from non-linear loads within the facility).
This presentation will focus on ways to mitigate the effects of internal and external transients from todays electrical loads. While the external surges are less than 10% of the surges in the facility, 90% are from internal sources. causing equipmentmalfunction or premature death of the load. To maintaingood power quality with reduced CAPEX and OPEX on your facility, certainmethods need to be adopted in removing the surges and transients. EP develops apatented waveform correction technology that addresses the two major powerquality issues without leaving any residual noise to the electrical load, thusprotecting the facilities investment.
What all designers/engineers need to know when doing projects to International Ex standards and some of the key mistakes to avoid...
In a global market for oil and gas, many projects involve hazardous location standards that are similar but different than what traditional US Installations require when it comes to Ex equipment and system designs. ATEX, IECEx, EAC, Inmetro and others all have similarities with regards to Ex equipment and systems as to design and requirements, but all require knowledge and skills in order to execute these projects on time and under budget. This discussion will look at some of the recent developments with regards to Ex standards for both electrical and non-electrical equipment, and what are some of the key requirements for designers and engineers to be aware of as well as some of the new developments that will be coming in the relevant IEC 60079 & 80079 standards down the road and how you can be prepared for your next International project.

Over current protection devices are timed to open once the available energy is low enough for safe interruption. In the case of instantaneous circuit breaker settings, the interruption occurs 3 – 8 cycles after the current is sensed. In the case of coordinated upstream devices,delays are longer… but usually within 30 cycles. What happens during that brief moment in time can transform “happy conductors” into “angry conductors”and can change the way you look at cable protection. In today’s arc-flash conscious world where the hazards caused by arcing faults are understood, and where perfect selectivity is mandated by codes, standards and good design practices… time current curves, interpreted in the traditional manner are no longer adequate tools to optimize the sub-cycle dynamic performance of cable systems. In order to protect valuable electrical infrastructure and personnel, we need to understand the physics of cable movement in order to ensure our designs are safe and robust.Full Bio
