UTILITY CONDITIONS:

For finding electricity data shall be referred to “Basic Engineering Design Data” or electrical document which is normally named “ELECTRICAL DESIGN CRITERIA”.

You can see sample ELECTRICAL DESIGN CRITERIA related to phase 2224 project.

ELECTRICAL DESIGN CRITERIA

• The motors with nominal voltages of 400 volt and below are referred to as low voltage (LV) motors.

The voltage of the motors 0.4 kW up to 150 kW shall be 400 volt three phase.

The voltage of 150 kW motors can be selected as 400 volt or 6000 volt depending upon the availability of such voltages.

The voltage of the motors rated up to 0.4 kW can be selected as 230 volt single phase and neutral.

• The motors with nominal voltages of 6 kV are referred to as medium voltage (MV) motors.

The voltage of the motors rated 150 kW to 1000 kW shall be 6 kV.

• The motors with nominal voltage of 10 kV and above are referred to as high voltage (HV) motors.

The voltage of the motors above 1000 kW can be selected as 6 kV or 10 kV.
