The electrical grid is segmented into different voltage levels to efficiently transmit and distribute power. These levels are generally categorized as follows:

• Low Voltage (LV): Typically below 1,000 volts (1 kV). This is the final stage of power delivery, supplying electricity directly to homes and small businesses. The voltage is reduced to common household levels, such as 120 V or 230 V.

• Medium Voltage (MV): Ranging from 1 kV to 69 kV. These lines are part of the local distribution network, carrying electricity from substations to smaller transformers in neighborhoods and industrial areas.

• High Voltage (HV) and Extra High Voltage (EHV): Starting from 69 kV and going up to 800 kV or more. These are the large transmission lines, often supported by tall steel lattice towers, that transport electricity over long distances from power plants to major substations.
