Its defined as the earth current (00:02:00) times the resistance of the grid.Basic grounding concepts and calculation inputs will be introduced, and the need for this type of modeling and analysis will be discussed.
Earthing Calculation Software Software Programs ToUsing software programs to model grounding systems and perform analysis is now standard for all but the simplest grounding designs, and commercially available programs have many uses. We will explain some of the most common uses of fully featured grounding programs and show example results for a simple grid design. Earthing Calculation Software Full Transcript OfWatch our most popular videos EasyPower OnSite Intro Utility Short Circuit Arc Flash Arc Flash Hazard Reduction Dynamic Stability Studies Full Transcript of the Video Mike Antonishen:Hi, Im Mike Antonishen. Im an electrical engineer at TriAxis, a division of David Evans Associates. Today were going to be talking about system grounding calculations. Earthing Calculation Software Free Support FromCoupled with toll-free support from the worlds leading RD design. Free Demo Download. The LPI Earthing Calculator is designed to give an indicative result to assist with the preliminary planning of an earthing installation. ![]() All calculation use formulas taken directly from recognised IEEE and. The type well be discussing today are most commonly associated IEEE 80, which is the IEEE guide for safety and AC substation grounding. Power and electrical system grounding is a massive topic and can be very confusing. So today were just going to go over the basics of what the calculations are, where and when to use them, with some examples from the real world sprinkled in. So, like I said, well cover grounding and grounding calculation basics. Well get into an intro to calculations, inputs in modeling, then well cover some brief examples of the IEEE step and touch calculations and some software examples. ![]() Earth current or grid current, or ground current as its sometimes called. Earth current is defined as the current flowing through our local grid and back to some remote source through earth. This current leaks to earth out of the local grounding facilities and leads to local ground potential rise. It is this ground potential rise that causes our safety issues. So ground potential rise is defined as the maximum electric potential that a grid and the surrounding soil may attain relative to remote earth. Under normal conditions, with no fault in your grid, its close to zero. Its a pretty simple calculation to get maximum potential rise.
