NOTES ON ELECTRICAL ENGINEERING
Transmission Voltage = 161kVHigh Voltage Distribution supply System =33kV/11kV
Low Voltage Distribution Line = 415 V - 3 phase (normally 3 wire for industrial application supply)
Single-phase used in our homes = 240V
(normally 4 wires on the pole known as distribution or service cable) the 4 wires being L1; L2; L3 and last as N)
