The calculations within this live spreadsheet will facilitate the initial design and engineering of many types of process piping systems. When various factors are typed into the Input cells, Excel will calculate results automatically. In addition, the powerful tool, "Goal Seek" can be used to optimize each design Calculation. Course Summary The following video shortly demonstrates how lightning protection calculation works in primtech. Choose between wires and rods and let primtech quickly do th... I have used this equation to design ground grids for Cell Sites across the Mid-Atlantic in the U.S. and most of the time the numbers were fairly accurate. Earlier this year I had the oppurtunity to perform a soil resistivity test for a new railroad substation and in order to due the test corectly I used the IEEE 80-2000. The PJM Transmission and Substation Design Subcommittee (TSDS) was requested to review and update the existing Outdoor Substation Conductor Ratings, Revision 1 document issued by the TSDS on December 16, 2004. This document contains ampacity ratings for tubular bus and stranded conductors used in substations and was based on I have prepare this course based on actual design calculations for actual 380/132/11kV Substation. Explained in detail topics step by Step. Introduction. Collecting information of substation , total line and transformer etc. Collecting Network Data. Explaining Short Circuit Level, Fault Clearance time, Thermal Time The intent of this calculator is to provide information pertinent to safe grounding practices in ac substation design. The specific purposes of this calculator are to: a) Establish, as a basis for design, the safe limits of potential differences that can exist in a substation under fault conditions between points that can be contacted by the ... Our civil engineers can perform complete civil design of Substation buildings either manual excel calculation or by using staad software and prepare the following drawings : 1. Foundation RCC details 2. Plinth beam and column RCC details 3. Roof beam, roof slab RCC details 4. Cable trench RCC details 5. Lintel beam, Stair case RCC details The calculations within this live spreadsheet will facilitate the initial design and engineering of many types of process piping systems. When various factors are typed into the Input cells, Excel will calculate results automatically. In addition, the powerful tool, "Goal Seek" can be used to optimize each design Calculation. Course Summary Substation design calculations excel Substation design calculations excel Substation design calculations excel Design calculations establish minimum guidelines and requirements for generating electrical calculations on projects. Electrical calculations should be made for all SPU projects that include electrical components and should be filed in the project notebook. Design calculations may be made either manually or by SPU-approved computer programs. Oct 03, 2020 · Create an excel program template to verify your calculation and to use with other values (assume for condition where the earth is uniform in composition). Soil resistivity = 220 Ω‐m Earth rod = 19 cm dia. x 3 m The earth is uniform in composition. 4. Verify the design safety of an outdoor substation with the following particulars.

CED Engineering offers online PDH Courses for continuing education. PE Continuing Education. enclose substations with energized electrical conductors or equipment. n This metal fence grounding requirement may be accomplished by bonding the fence to the substation grounding grid or to a separate underground conductor below or near the fence line using the methods described in the NESC. Earthing Calculations regarding your safety – you’re overdue an update! If 1-ohm is still in circulation on your documentation then this section applies to you.. Even though the Earthing Calculations for determining a safe System Earth (Ground) has shifted away from an arbitrary resistance figure, usually <1 ohm. Volume I, Design Parameters. Covers the general design considerations, documents and drawings related to designing a substation. Volume II, Physical Layout. Covers the layout considerations, bus configurations, and electrical clearances. Volume III, Conductors and Bus Design. Covers bare conductors, rigid and strain bus design. Electrical tools (MS Excel Spreadsheets) This section is dedicated to tools every electrical engineer can use in daily work.These spreadsheets below will make your job much more easier, alowing you to shorten the time used for endless calculations of cables, voltage drop, various selections of circuit breakers, capacitors, cable size and so on. utility line design calculations The following calculations are included in the website, requires minimal training and take seconds to perform. Utility Line Design has over twenty-five planned calculations that will be added to the website at no added charge in the coming months. substation design.

The Manager Substation Design is the Subject Matter Expert (SME) for the content and shall The calculation will in cases like these be a little more com- plicated and trial calculation is the best way. The voltage at the receiving end is assumed “ E’ 2 ” and from this value a voltage “ E’ 1 ”, at the sending end is calculated. Step#9: Comparing The Computed Mesh Voltage From Step#8 With The Tolerable Touch Voltage From Step#3 Step#10: Comparing The Computed Step Voltage From Step#8 With The Tolerable Step Voltage From Step#3 Step#11: Preliminary Design Modification Step#12: Detailed Final Design You’ll create design documents, technical specifications, and drawings for new substation projects including electrical plans, schematics, bills of materials, and equipment specifications. You’ll prepare substation design calculations including grounding, DC loading, AC Aux power loading, bus sizing, lighting and cable sizing. enclose substations with energized electrical conductors or equipment. n This metal fence grounding requirement may be accomplished by bonding the fence to the substation grounding grid or to a separate underground conductor below or near the fence line using the methods described in the NESC.
