Applying the ErP Directive to motors and their protection
Eaton has produced a pair of White Papers that cover aspects of the ErP (energy-related products) Directive. The first paper, Motor Protection for the IE3 revolution, explains why IE3 motors have higher starting currents and how this affects the requirements placed on switchgear and protection technologies. The second paper, Successful implementation of the ErP Directive, uses concrete examples to show how losses can be reduced using speed controls, and explains how best to tackle electric motor efficiency. It presents several different technical solutions.
