Jinsi ya kukokotoa Cable Voltage Drop2
Cable Voltage Drop2 ni nini?
Calculates voltage loss in electrical cables due to resistance. High losses reduce efficiency and can prevent motor starting.
Fomula
Formula: voltage drop = (2 × length × current × resistance) ÷ 1000
Mwongozo wa Hatua kwa Hatua
- 1Current in amperes and cable length
- 2Wire gauge (affects resistance)
- 3Formula: voltage drop = (2 × length × current × resistance) ÷ 1000
- 4Typical target <3% for power, <5% for control
- 5Higher gauge wire reduces drop exponentially
Mifano Iliyotatuliwa
Ingizo
100A, 50ft, 10 AWG
Matokeo
3.2V drop
Makosa ya Kawaida ya Kuepuka
- ✕Using undersized wire to save cost
- ✕Not accounting for temperature derating
Maswali yanayoulizwa mara kwa mara
Why does voltage drop matter?
Reduces equipment voltage, increases losses, causes motors to start slowly, reduces efficiency.
How much does proper wire size cost vs. undersized?
Proper size costs 10-20% more initially but saves 5-10% energy costs over life.
