Buenos días Ing. Edvard cordial saludo, quisiera saber cuando abra una hoja de cálculo de las que ofrecen en forma gratuita, por qué me pide contraseña y si trato de buscarla me dice que debo pagar.
Cómo desbloqueola hoja en Excel para poder trabajar.
Ejemplo la hoja de Nivel de Cortocircuito?
Quedo atento a su respuesta
Feliz día

sir
kindly let me know the cable size calculation complete formula and explain how to use that formula .Even i want to know the various design aspects of electrical design of cable size ,cable selection,
Josh Shelton
Very handy tool. Would like to see the cables listed in AWG size also and standard measurements compared to metrics. I am an American, we are different, haha!
Edson Viana from Brazil
Hi Edvard, good afternoom
Please, do you have a sheet plan to short circuit in CC?
Best regards.
Edson

Hey edward could you please send me a copy of the short circuit calculator xls. Your help would be very much appreciated. Thank You .
Bilal mohamed
Dear sir
i have three question
1-could i know the formula you used from which standard or code you take it ?
2- for Phase Conductor Constant , can you send me the catalogs which took from (because it different from country to other ) ?
3- Do you have an AWG cable size equivalent ? (whith mention your resource )
best regards

you may also consider Short Circuit Analytic software program and mobile apps for short circuit fault current calculations. The program factors in both active and reactive parts of equipment impedance and takes into account fault current contributions from multiples sources including motors and generators:

Thank you for your support.
Can you please send me a format for calculating Isc for a panel fed from generator. (e.g. 2.75MVA CAT Genset feeds to a Panel of 4000A, 415V, 4C armored cables).
Or please advice to: faruqueahmad39@gmail.com

As a registered member (and you are), normally you should see download link ‘Right here’.
If you have problem with downloading, please send me email on office at electrical-engineering-portal dot com

Could you please develop the Excel calculation sheet for sizing of Soft Starter with the curve appearance.
Edvard
EEP is not the developer of any MS Excel Spreadsheet here. All spreadsheets are developed by engineers who wanted to share their entusiasm and knowledge with everybody.

Hello, could you please solve the short circuit problem manually using point to point calculation. A better explanation on how you arrived at your answer would also be appreciated. Kindly send your reply to: tosin.fayinminu@deltaafrik.com or fayinminutosin@yahoo.com.
• One 480V motor feeder, 100HP, 100m length, for both underground installation and offshore installation in cable trays. Assume MCC is fed from switchgear, on the secondary of a 750kVA transformer, 4160-480V. The check for Voltage drop should be for running and starting conditions
• One feeder cable to a Power Panel, 480V, 100kVA, 200 m distance
• One 250 HP, 4.16kV motor, 100m length for both underground and cable tray installation. Assume 4.16kV MCC is fed from 4.16kV switchgear having a short circuit rating of 200MVA, the feeder length is 50Ft.
• One remote 4.16kV-480V transformer feeder, 200m length, 500kVA.
• One line diagram for the system (4.16kV and 480V) shall also be prepared.
• Primary short circuit calculation (using reactance and resistances in ohms, not p.u.)
• Assume the generation is with 2+1 1250kVA, 4.16 kV Solar Saturn 20 gas turbine generators (sub transient reactance is 12.5%).
