Conductors

The 11 kV feeders carry comparatively bulk power from secondary substation (33/11 kV) to distribution substation transformers (DTRs). Distributors (or secondary network) carry power from DTRs through service lines (or LT feeders) that deliver power from the supplier's nearest support to consumer's premises up to the energy meter, by a weather-proof service wire.

All lines have inherent resistances, inductances and capacitances, resulting within a voltage drop in the line. Therefore, to minimize voltage drop in a line, the values of these parameters should be carefully selected. For LT supply, the declared voltages at the consumer premises are 415/240 V. All appliances and motors provide good performance for long duration if this voltage is managed.
