Types of Power optimisation

Electrical utilities transmit electricity at high voltages, and as a result every building is served by at least one electrical transformer to lower the voltage so it can be utilised by the building.

For many buildings this transformer is provided by the electrical utility company and may be located on-site or mounted off-site, somewhere nearby. The high voltages are reduced by the transformer to the lower voltage levels before it enters the main building.

  • In this scenario the types of power optimisation to be considered are LV side optimisation and the recommended solutions are Powerstar MAX or Powerstar LITE

Some larger buildings can receive electricity more efficiently by obtaining their electricity from the utility at the higher voltage levels and supplying their own on-site transformer to reduce voltage levels before it enters their building.

  • In this scenario the type of power optimisation used should be HV side optimisation and the recommended solution is Powerstar HV MAX

Voltage optimisation should not be confused with step-down transformers or simple voltage stabilisers which only reduce the voltage and do not offer the energy saving benefits of a true voltage optimisation system.

Integrating with energy storage

Powerstar MAX or Powerstar HV MAX systems can be integrated with Virtue, an energy storage system which allows companies to store energy generated during periods of low demand and switch to this stored supply at any time
