Where can I find information on voltage management?

Voltage management technology can cut carbon and reduce costs when applied to sites with well suited load types and where voltage levels can be easily reduced.  However prospective customers should understand the limitations as well as any potential benefits before investing in this technology.

We have consulted with voltage management suppliers, electrical equipment manufacturers, trade bodies and electrical industry experts to produce an introduction to voltage management technology and techniques.

The guide provides an impartial view on voltage management technology, the concepts behind calculating savings and guidance on where it can be applied.

The guide provides insight into:

  • The theory of saving energy by reducing voltage.
  • The concepts of voltage dependent and voltage independent loads.
  • Voltage management techniques.
  • Evaluating site potential for voltage management.
  • Calculation of possible energy savings.
