Installed power loads - Characteristics

An examination of the actual apparent-power demands of different loads: a necessary preliminary step in the design of a LV installation

The examination of actual values of apparent-power required by each load enables the establishment of:

• A declared power demand which determines the contract for the supply of energy
• The rating of the MV/LV transformer, where applicable (allowing for expected increased load)
• Levels of load current at each distribution board
