Electrical Network Details:

For carrying out studies, the sub-transmission and distribution system and its backup system from Grid substations to the consumers' level should be detailed. The data requirements for analysis of the existing power system are:

1 Electrical network details: single line diagrams with conductor sizes, lengths, transformer locations, transformation capacities, capacitors, consumer location and load, etc.;

2 Parameters of equipment, devices and conductors; and

3 Load data: peak load, diversity factor and power factor.

Sub-transmission and Distribution Network

Electrical network mapping should, in the first phase, be prepared as single line diagram showing the network layout. The network diagrams should be prepared for each and every substation and line section up to LV bus of the distribution transformer.
