Electrical Engineering Tools is a practical collection of electrical engineering calculators and tools designed to help engineers, technicians, students, and engineering professionals perform common electrical calculations quickly and easily.

The app provides practical calculation tools for everyday electrical engineering work, including:

• Voltage Drop Calculator
Calculate current, voltage drop, and voltage drop percentage for electrical circuits.

• Cable Size Selection
Select a suitable cable size based on load current, allowable ampacity, voltage drop, cable length, insulation, conductor material, and derating factor.

• Short Circuit Calculator
Calculate short-circuit current at transformer terminals and at the cable end, with support for different system and fault conditions.

• Transformer Sizing Calculator
Select a suitable transformer rating according to load power, power factor, primary and secondary voltage, and future expansion.

• Motor Starting Voltage Drop & Cable Sizing
Evaluate motor running current, starting current, allowable ampacity, recommended cable size, starting voltage drop, and starting voltage drop percentage for three-phase and single-phase motors.

• Power Factor Correction Calculator
Calculate the required capacitor-bank kVAr to improve the load power factor, including initial and target power factor, reactive power, initial current, and corrected current.

• Conduit Fill & Conduit Filling Ratio
Calculate cable/conduit fill using NEC-based rules. The app supports multiconductor cable fill and automatically determines the NEC cable-size category from the selected cable size. For NEC single-conductor cable fill, cable tray options include ladder, ventilated trough, and wire mesh cable tray.

• Saved Results
Save calculation results and review previously saved calculations with their input and output details.

• Projects
Organize engineering calculations into projects for easier management and reference.

Electrical Engineering Tools is designed as a practical calculation assistant and reference for everyday electrical engineering tasks.

Important Note:
The results provided by the app should be reviewed and verified by a qualified engineer before being used in actual projects, designs, or engineering decisions.
