Water Industry System Efficiency

There is a new consideration for water utilities when determining their next move towards using less energy. It is tucked away within something called electrical system efficiency. An electrical system is needed to power pumps and typically comprises a transformer, variable speed drives (VSDs), electric motors, switchgear and cabling. Quite often when specifying such a system, designers simply multiply the catalogue efficiencies for each component to get an overall system efficiency. For example, if each…
