Calculates voltage loss in electrical cables due to resistance. High losses reduce efficiency and can prevent motor starting.

ସୂତ୍ର

Formula: voltage drop = (2 × length × current × resistance) ÷ 1000

ଷ୍ଟେପ୍-ଷ୍ଟେପ୍ ଗାଇଡ୍ |

  1. 1Current in amperes and cable length
  2. 2Wire gauge (affects resistance)
  3. 3Formula: voltage drop = (2 × length × current × resistance) ÷ 1000
  4. 4Typical target <3% for power, <5% for control
  5. 5Higher gauge wire reduces drop exponentially

  • Using undersized wire to save cost
  • Not accounting for temperature derating

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.
