How to used Voltage Drop Calculation Software

1. TO INDICATE THE CIRCUIT FROM The column shall be indicate the name of the Board of the outgoing cable that need to calculate the voltage drop



2. INDICATE THE CIRCUIT GOING TO
   The column shall be indicate the name of the board connected to the cable that need to calculate the voltage drop



3. MAXIMUM DEMAND
   Maximum demand or the desired power in kW.



4. SPARE LOAD PER CIRCUIT
   Enter the desired spare power particularly used for sizing the incoming breaker where usually sized for 1.2 times the maximum demand current or if any spare capacity is required.The total power used for the calculation will be the MD power + spare kW.



5. VOLTAGE APPLIED The voltage that supplied to the system / circuit (currently this software only support 415V)



6. PHASES The system current supply (currently this software only support three phase). So enter ‘3’ in this column.



7. POWER FACTOR
   - The system power factor as Authorities provider (default 0.85)
   - For generator set supply shall be 0.8



8. CABLE LENGTH
   - The distance (in meter) from the incoming board to outgoing board



9. SET VOLTAGE DROP (%)
   - Set the desired limit of maximum voltage drop for the cable in percentage.
   - The set of voltage drop (the whole system shall be not more than 4% for the particular circuit
