02Voltage Drop Estimator
Preliminary voltage drop estimate.
Result
ΔU
9.35V
ΔU / Un
2.34%
ΔU = √3 × L × I × ρ × cosφ / S
Assumptions:
- ρ copper = 0.0225 Ω·mm²/m
- Reactance neglected
- Balanced load, line-to-line voltage
Preliminary estimate for orientation only. Reactance, temperature, grouping and installation conditions are not included. Final sizing requires a project-specific engineering calculation.
