LV & MV Electrical Installations III: The Absence of the IDR and Deaths Due to Electric Shock in the Residential Environment

Electrical Engineer, specialist in Photovoltaic Solar Energy Projects in MMGD and self-production. He has developed more than 500MW of projects for Parecer de Acesso in 24 concessionaires across the country. He actively participated in the ABNT commission that developed NBR 16690. He has been a speaker at the main events in the solar energy sector and a course instructor in the area of solar energy electrical installations, having trained more than 600 technical and engineering professionals. He is currently President of Abracopel, a board member of ABGD and Technical Director of Sindistal-RJ.

Formed by the interaction of lessons from family, friends and the academic world, be it a PhD in Mechanical Engineering from the University of São Paulo - USP, a Master's in Civil Engineering in Housing: Planning and Technology from IPT, a postgraduate degree in Occupational Safety from FAAP, a degree in Electrical Engineering from FEI (Fundação Educacional Inaciana Padre Saboia de Medeiros), as well as a period as a researcher at the Technological Research Institute of the State of São Paulo - IPT. He works in the field of Fire Safety - SCI, with an emphasis on forensics involving fire and explosion issues in all their diversity. Never forgetting that my professional career began at Metrô-SP, where I was taught the Code of Conduct: Safety, Speed and Comfort.

He holds a bachelor's degree in Electrical Engineering from the Federal University of Ceará (2002) and a master's degree in Electrical Engineering from the Federal University of Ceará (2005). Since 2021, he has been studying for a PhD at the Universitat Politècnica de Catalunya BarcelonaTech, where he is developing research in the area of inverter parallelism and synchronization systems for distributed generation systems connected or not to the electricity grid. He is currently an adjunct professor in the Department of Electrical Engineering at the Federal University of Ceará, where he teaches Building and Industrial Electrical Installations. He also works as a technical consultant in the areas of Electrical Installations, Energy Quality, Energy Efficiency, Renewable Energies, Power Electronics, Protection of Electrical Power Systems and Electrical Systems.

He has a degree in Electrical Engineering from UFU and a master's degree in Electronic Engineering from ITA. He founded Mi Omega in October 1993 and has been at the forefront of the company's technical solutions ever since. He has been a member of the ABNT commission responsible for revising standard NBR 5410 - Low-voltage electrical installations since 1993, coordinator of the ABNT commission responsible for revising standard NBR 14039 - Medium-voltage electrical installations since 2003, member of the NBR 16384 - Safety in Electricity commission in 2020, member of the NBR 16690 - Electrical Installations of Photovoltaic Arrangements commission since its inception and member of NBR 15751 - Substation Grounding Systems - Requirements. Currently, as well as heading up Mi Omega, he also teaches courses at the Mi Omega Institute and has over 40 years' experience in the electrical sector.

Marcos Rogério Chaves da Silva is an Electrical Engineer (UMC), with an MBA in Business Management and a Specialization in Project Management, both from FGV-SP. For four decades he has been working on LV and MV power protection systems, and has experience in developing distributed power generation projects for terrestrial and embedded applications, LV and MV protection and selectivity studies and protection against the effects of incident energy emitted by arc faults. He is currently Director of TECPRO Soluções em Energia. He actively participates in various committees of CB-03 at COBEI - Comite Brasileiro de Eletricidade. He is secretary of the NBR 14039 standard revision committee, secretary of the NBR 16384 revision committee and rapporteur of the WG responsible for the future Incident Energy Management standard. At CB-24 ABNT, he is the Coordinator of the Committee responsible for developing the future technical standard 'Fire safety in photovoltaic installations'. He is Brazil's representative on IEC committees PC128 and TC99.
