Electrical design and verification work involves dozens of repeat calculations — voltage drop on a feeder, transformer impedance, cable current rating, relay pickup settings, earth fault current. Building each of these from scratch wastes engineering hours and introduces the risk of formula errors. The Electrical Engineering Calculations Excel Templates Bundle from GrowMechanical packages the most commonly needed electrical calculation sheets into one ready-to-use set, so you can enter your project data and get verified results in minutes.
It is built for electrical design engineers, EPC project engineers, panel and switchgear designers, plant electrical maintenance teams, and engineering consultants who need dependable, editable calculation tools for daily project work.
What’s Included in This Bundle
- Load list and demand load estimation
- Voltage drop calculation for LV and MV feeders/cables
- Transformer sizing and impedance calculation
- Cable sizing (current rating, derating factors, short-circuit withstand)
- Short-circuit current calculation
- Relay and protection coordination settings
- Earthing/grounding system sizing
- Motor starting current and voltage dip calculation
- Power factor correction and capacitor bank sizing
- Lighting load and illumination-level calculation

Frequently Asked Questions
Does this bundle include single-line diagrams or AutoCAD files?
No. This bundle focuses on calculation spreadsheets — load flow, voltage drop, transformer sizing, cable sizing, short-circuit, relay settings, earthing, motor starting, and power factor. It does not include drafting or diagram files.
Why is this bundle delivered on a USB flash drive instead of a download?
This bundle ships on a dedicated USB flash drive for convenient offline use and as a physical backup copy of your templates. Delivery details are confirmed at checkout.
Are the calculation formulas editable?
Yes. Every formula and cell is open for review and editing, so you can adapt inputs, units, or margins to match your project standards.
Which standards are these calculations based on?
The templates use standard electrical engineering formulas commonly referenced in IS, IEC, and NEC-style practice for load, voltage drop, cable sizing, and protection calculations. Always validate results against your project’s governing code and client specifications.
Can I use this bundle for EPC project calculation packages?
Yes. The templates are structured to support calculation documentation for EPC submittals, design reviews, and client handover packages.
