The Rolling Sphere Method is a direct application of the Electrogeometric Model (EGM) for lightning protection. It provides a practical method for engineers and architects to design lightning protection systems to shield their high priority assets from direct strikes. This presentation will go over the need for this method and will teach engineers how to apply the method to substations per IEEE Std. 998 and NFPA 780. While the presentation focuses on protecting substations, the concepts can be universally applied to any asset since lightning does not discriminate.

Biography:

Biren Patel is a Substation Design Engineer with 15 years experience working on high voltage transmission substations for electric utilities. Biren and his company also have been designing solar plants and solar interconnections for developers and EPCs for 9 years. Biren graduated with a BSEE from Ga Tech in 2005 and an MBA from UGA in 2012. He is a PE in 15 states, a certified PMP, and an IEEE member since 2003. In 2011, he left his first substation engineering job at Burns & McDonnell to start the poorly named company, Biren Patel Engineering. He, his wife, and his 3 year old son live in Macon, GA. According to his wife, the only reason he does these presentations is because he loves to hear himself talk and thinks he's a lot funnier than he really is.

We started Biren Patel Engineering with the goal of making life simple for our clients and our employees. We have a small company of 20 electrical engineers and designers all working from home (before we had to) in various locations, mostly in the Southeast. We currently perform substation, protection and control, and relay apps & settings work for utilities including Southern Company, Duke Energy, FPL/NextEra, MEAG Power, and Georgia Transmission Corp. Although substation work is our first love and primary service, we also consult for solar developers and EPCs as they seek simple answers in a complex utility world.
