Lessons learned from 20 years with plant electrical and control systems

Waste Solutions, now a division of CPG NZ Ltd, has specialised in the design, upgrading, control and operation of municipal and industrial, water, waste treatment, waste to energy plants and reticulation systems for over 20 years. During this period staff have had the opportunity to observe and learn from a variety of plants and clients, both public and private, in a number of areas of the world.

This paper considers both general and, more particularly, some electrical and control lessons learnt during the last 21 years the author has had in the design and operation of such plants, and reviews these in a way that we hope others will be able to learn from our experiences.
