Substation Awareness


Substations are located around the country. They are used to step  down high voltage electricity from the transmission system into lower voltage electricity, to supply to homes and businesses through lower voltage distribution lines. Power and electricity distribution companies are responsible for substations and the power lines networks that feed them and provide electricity to your home or business. You will see substations dotted around your locality of varying sizes depending on the output required of them.

There are four main types of substation:

  • Low Voltage Secondary Substations  
  • High Voltage Substations (HV Substations) – Involving voltages between 11kV and 66kV
  • Extra High Voltage Substations (EHV)– Involving voltages between 132kV and 400kV
  • Ultra High Voltage(UHV) – Operating voltage above 400kV

This Citrus Substation Awareness qualification takes delegates through the awareness and regulatory requirements of electrical substations specifically.
