Electrical Engineer Calculator
Your all-in-one electrical engineering toolkit
Fast, accurate calculations for voltage drop, cable sizing, fuses, power factor correction, fault diagnosis, motors, transformers, and pumps. Perfect for engineers, technicians, installers, maintenance staff, and students.
⚡ FREE CALCULATORS
📉 Voltage Drop – Single & three-phase circuits. Compliant with ELOT HD 384 & IEC standards.
📏 Cable Sizing – Find the right cross-section based on load current and line length.
🔌 Fuse Selection – Get the ideal fuse rating automatically.
⚡ Power Factor Correction – Calculate capacitor values in kW, W, or HP.
🩺 Fault Diagnosis – 40+ common electrical faults with causes and solutions.
🔧 MOTOR CALCULATOR (FREE)
Current, Power, Torque, Efficiency, Slip, 3φ→1φ capacitor sizing, and Starting capacitor selection. All in one place.
📐 TRANSFORMER CALCULATOR (FREE)
Ratio K = U1 / U2, primary & secondary voltage, auto-detects Step-Down, Step-Up, or Isolation.
💧 PREMIUM PUMP CALCULATOR (IAP)
Advanced hydraulic calculations – m³/h & l/s support. Includes flow velocity, Reynolds number, Darcy-Weisbach friction losses, local losses (Σξ), manometric head, hydraulic/shaft/motor power, and laminar/turbulent flow type.
🌐 6 LANGUAGES – Greek, English, German, French, Italian, Spanish.
🎨 MODERN UI – Material Design 3, Jetpack Compose, Dark Mode, copy results, one-tap clear.
