• Load & maximum demand calculation

• Transformer sizing calculation

• DG sizing calculation

• Short circuit calculation

• Voltage drop calculation

• Capacitor sizing calculation

• Cable sizing calculation

• Earthing calculation

• Lighting calculation

• UPS/Inverter sizing calculation

• Battery sizing calculation





7. Various design stages & Sequence of electrical design procedure



Concept design stage:



• Understanding the building plans, elevations & sections

• Gathering specific data from the utilities(Electricity board)

• Understanding clients specific requirements

• Assessment of the type of installation like outdoor/indoor substation(Point of supply)

• Preparation of basis of design which should include the cost estimate.



Schematic design stage:



• Preparation of Load calculation to arrive maximum peak demand

• Sizing of all Equipments,cables,cable trays

• Electrical design calculations

• Preparation of single line schematic of electrical distribution system with metering options

• Preparation of equipment layouts like Substation, plant rooms.

• Preparation of lighting, small power, earthing & miscellaneous layouts

• Preparation of technical specification



Detailed design stage:



• Preparation of detail layouts including sectional details wherever required

• Coordination with other services like HVAC,PHE & FF layouts

• Preparation of bill of quantities(BOQ)

• Issue for tender



Construction design stage:(Generally this stage is performed by electrical Contractors)



• Preparation of shop drawings based on the tender drawings issued by

Electrical consultants for installation.

• After installation the entire installation shall be tested & commissioned with the respective authorities.

• As built drawings shall be prepared and handed over to client’s representative.
