What You Need To Know About Arc Flash Hazard Study And Analysis

Published by Carelabs (Carelabz) Arc flash study came into picture ten years ago when IEEE 1584, known as “IEEE Guide for Performing Arc Flash Hazard Calculations,” was first introduced. This landmark document defines equations and methods that have become key components of the arc flash study. In order to identify the specific arc flash hazardContinue reading “What You Need To Know About Arc Flash Hazard Study And Analysis”

What You Need To Know About Arc Flash

Published by Carelabs (Carelabz) Arc Flash is an energy release that takes place when electricity flows through the air and two live conductors causing short circuit. In a residential setting, arc flashes usually produce little more than a brief flash of light before extinguishing themselves harmlessly. In commercial or industrial setting, voltages are high, soContinue reading “What You Need To Know About Arc Flash”

OXTO Energy: A New Generation of Flywheel Energy Storage

INERTIA DRIVE (ID) THE NEXT GENERATION FLYWHEEL The Inertia Drive technology is based on the flywheel mechanical battery concept that stores kinetic energy in the form of a rotating mass. Our innovations focus on design, assembly and manufacturing process. Solar and wind power only produce when the wind is blowing or the sun is shining.Continue reading “OXTO Energy: A New Generation of Flywheel Energy Storage”

What is Cable Testing and How is Cable Testing Done?

Published by Carelabs (Carelabz) Cabling is an expensive business and must be treated carefully. The expenditure of substitution once the routes are all concealed is bigger. The fault is not always visible like crushing, bending or kinking. Make sure that your cabling installer have made provision to protect installed cabling from other worker’s actions. ThisContinue reading “What is Cable Testing and How is Cable Testing Done?”

How And Why Do We Need To Conduct Electrical Safety Testing

Published by Carelabs (Carelabz) Making a product “safe” requires an understanding of the “hazards” that exist in each electrical product. Certain potential hazards are inborn in all electrical products because of the manner in which they are powered and how they perform their intended functions. Even though a product requires an electrical power source and usesContinue reading “How And Why Do We Need To Conduct Electrical Safety Testing”

Section 4: System Voltage Considerations

Published by Bill Brown, P.E., Square D Engineering Services. Basic Principles The selection of system voltages is crucial to successful power system design. Reference [1] lists the standard voltages for the United States and their ranges. The nominal voltages from [1] are given in table 4-1. As can be seen, ANSI C84.1-1989 divides system voltagesContinue reading “Section 4: System Voltage Considerations”
