IEEE Las Vegas PES Chapter

January 8th, 2019

Electrical Utility Batteries and Charging “Lunch and Learn” with IEEE PES Las Vegas.
Location: 6226 W Sahara Ave, Las Vegas, Wengert room
Date: 02/26/2019
Time: 11:30am – 2:00pm lunch and presentation. (Lunch will be provided at no cost)
Topic: Electrical Utility Batteries and Charging
Speakers: Art Salander and Eric Cogorno

Overview: Battery History – a brief enjoyable look at the development of storage batteries dating back to the 1700s right up to the 21st century.
Battery Types and Sizing Techniques – We examine how storage batteries are sized manually. This includes demonstrations plotting load profiles, different technologies and how they respond, etc. this will enable you to understand how the battery manufacturer’s computer programs actually work.
Battery Charger Sizing – how we have been doing it and how we think it should be done in the future.
Battery charger specifying. Protective devices in dc utility systems. Redundancy using steering diodes. Compliance and Supervisory System- NERC compliance as it relates to batteries. Designing a supervisory system for utility DC applications. Live demos of some new products for the utility DC user.

Art Salander – Art Salander has spent 40+ years in the stationary battery/dc power industry. Among his accomplishments, he has spoken for many industry groups and published numerous articles and papers on industry relevant topics. Further, he generally is requested to provide presentations on topics ranging from Battery History, sizing batteries and battery chargers, specifying assistance and much more. Art’s other accomplishments include being the chairmen of the IEEE Stationary Battery Committee’s WP2405 to work with and update the NEMA PE5 standard for utility battery chargers.
Currently, Art Salander provides application engineering and business development for HindlePower, Inc., the leader in utility battery chargers and related dc He holds a physics/engineering degree from Adelphi University with post-graduate studies at NYIT, and he is an IEEE senior member.
Eric Cogorno – Eric is a member of the sales and marketing team at HindlePower, the leader in utility battery chargers and dc equipment. Prior to joining HindlePower, he graduated from Lincoln Technical Institute and more recently Albright College. Over his 13 years with the company, he has developed vast knowledge and experience in the manufacturing, testing, and design of stationary battery chargers. Further, he has developed application experience in the battery/dc power industry as a whole and is well versed in sizing chargers and specifications. Eric has also attended and participated in the IEEE Stationary Battery Committees WP2405 that is working to update the NEMA PE5 standard for utility battery chargers.
All attendees will be given a book, “Charge!: Everything You Always Wanted to Know About Stationary Chargers” written by William K. Bennett, an IEEE engineer with 40 years in the field.

IEEE PES presents “Lunch and Learn”
Location: NV Energy, Pearson building, Wengert room, 6226 W. Sahara Ave
Date: 12/22/14
Time:  12:00 – 1:00pm presentation (lunch available for purchase at Steve’s Diner, open at 11:00 am)
Topic: Arc-Flash Safety—an utility Experience
Speaker: William Esposito, P.E.
Arc-Flash Safety Compliance—an utility Experience Arc flash is a flash over of electric current that can reach as high as 35,000°F (19,400°C.) Arc flash safety is a main concern for electric utility workers who have to work with energized equipment all the time. Mr. Esposito will explain the nature and causes of arc flash and share the experience in determining the proper arc flash protections.

Mr. Bill Esposito is the Manager of the Power Systems Engineering, Substation and Transmission group for NV Energy, a Berkshire Hathaway Energy utility company which serves most of the state of Nevada, including Las Vegas, Reno and Laughlin. Mr. Esposito has been involved with the electric utility industry for over 30 years, including 18 years at NV Energy. He is a Registered Professional Engineer in both New York and Nevada, and graduated from Rensselaer Polytechnic Institute.
