Modern Instantaneous Selectivity, The Code, Arc Flash and System Reliability

Subject:  Modern Instantaneous Selectivity, The Code, Arc Flash and System Reliability

Speaker:  Marcelo E. Valdes

Designing safe and reliable electrical distribution systems consistent with the mission of the system and conscious of budgetary and schedule limitations has always been the intent of the good electrical systems designer. However, in recent years, increasing focus on arc flash and electrical safety as well as clauses within various codes have influenced the electrical designer to considerthe compromise between protection and system reliability differently. Achieving selectivity at the expense of protection, or protection at the expense of selectivity is neither desirable, nor consistent with good engineering practice anymore. Luckily manufacturers have provided product solutions and associated analytical techniques that allow designers to offer excellent protection and significant selectivity simultaneously. Understanding how protective devices really work and how to implement them is the key to achieve the potentially competing goals of maximum protection and maximum selectivity simultaneously.
Marcelo E. Valdes has been with GE 36 years in various assignments including field engineering, sales and marketing management. Currently he is manager of Application Engineering for GE’s Industrial Solutions business based in Plainville Connecticut. Marcelo has published mover 20 papers in IEEE conference journals, IEEE IAS Transactions, IAS magazine and other industry publications. He has 13 patents and over 30 applied for in the area of circuit breaker trips and protection algorithms. His patents and papers primarily focus on selectivity and arc flash energy mitigation. Marcelo is chair of an IEEE project to produce a guide for the specification of safer Motor Control Centers, and an active participant in various IEEE working groups developing the IEEE Dot standards that will replace the IEEE color book as well as IEEE 1584 “Guide for Arc Flash calculations” and other standards relating to circuit breakers and electrical safety. Currently Marcelo serves as the NEMA alternate representative to Code Panel 17 for NFPA 70. Mr. Valdes is the past Vice Chair of the 2012 and 2013 IEEE Electrical Safety Workshop and Chair of the IEEE 2014 Electrical Safety Workshop to be held in San Diego California.

Electrical Reliability may sound like a boring topic until you look at the world around you.  On February 3, 2013, the Super Bowl sustained a power outage while nearly 109 million people watched and waited.  On September 9, 2011, Southern California, parts of Arizona, and parts of Mexico sustained a power outage leaving 1.5 million people in the dark and bringing traffic to a standstill.  On December 18, 2005, during heavy rainfall, a large wastewater treatment plant in the San Francisco Bay Area sustained a power outage on one utility service leaving the plant with only one healthy utility service for 5 days.  Power outages such as these can have widespread implications whether it is traffic gridlock or risk of sewage discharge into waterways.
The examples will be based on the speakers experience performing testing, startup, commissioning, and troubleshooting of power systems at a large wastewater treatment plant in the San Francisco Bay Area. The examples and recommendations will universally apply to all industries including Mission Critical, Oil and Gas, Healthcare, Utility, Transportation, Commercial, and Water/Wastewater.

Michael Nakamura is a Sales Engineer with MatzingerKeegan, Inc. (MKI), manufacturer’s representative for Schweitzer Engineering Labs, Southern States, Myers Power Products, and others. Prior to joining MKI, Mr. Nakamura was a SeniorElectrical Engineer at the East Bay Municipal Utility District where he supervised the Wastewater Electrical Engineering section.
He has 19 years of experience in the design, construction, testing, startup, commissioning, and troubleshooting of power distribution, control, and automation systems at water and wastewater facilities. Mr. Nakamura received the B.S.E.E. degree from California Polytechnic State University at San Luis Obispo. He is a Senior Member of IEEE and is active in the local chapter of the Industry Applications Society serving as Chairman. Mr. Nakamura holds a Certificate in Project Management from UCBerkeley Extension, and is a Registered Professional Engineer in the State of California.1994. From 1995 to 2009, Dave held multiple Engineering, Sales, & Executive Management positions within the Power Systems Division of Michigan CAT, a Caterpillar Dealer covering the state of Michigan. From 2009 to 2012, Dave was V.P. of Sales for Kossen Equipment, a Kohler Power Systems Dealer covering the South East. He then became Director of Engineering & Product Development for Taylor Power, a Distributor of Perkins Engines and Manufacturer of Generator Sets.
