Voltage Drop Calculator per DIN VDE 0100-520
Calculate the voltage drop in your electrical cables and verify compliance with the 3% limit of DIN VDE 0100-520 instantly.
How to Use
Enter current type, cable length, cross-section, load current and power factor. The tool shows voltage drop in volts and percentage.
Why Voltage Drop Matters
- Prevents equipment malfunction from under-voltage
- Required for VDE compliance
- Supports AC and 3-phase calculations
- Instant 3% threshold check
