Explanation

  • Voltage drop analysis helps ensure the end-user receives the correct voltage needed for safe and reliable operation of electrical devices.
  • Regulatory standards typically specify that the voltage at a user’s point of connection should not deviate more than ±5% for most systems (e.g., from 230V nominal, the range would be 218.5V to 241.5V).
  • Excessive voltage drop can cause equipment malfunction or failure. Therefore, analyzing and minimizing voltage drop helps maintain power quality and protect end-user equipment.
  • Also, engineers can size conductors correctly, reduce losses, and maintain voltage within this acceptable range.
