Measurement for Energy efficiency and cost savings

From Electrical Installation Guide

Jump to: navigation , search

For this application, energy needs to be measured in order to make it more efficient, to allocate it within a plant, or to reduce its cost.

Energy efficiency aspects are dealt with in more details in:Energy Efficiency in electrical distribution

The main standards are specified below.
