ABB Rewiew 4/10 Pumps, Soft Starters, VFDs
(OP)
I received the ABB Review today. Quite often interesting and valuable information. This issue has a six-page article where the authors have researched different types of flow control in pumps. Different technologies, different motors (from Eff3 to IE3, via IE2 and 3) are compared and behaviour at partial load and with oversized motors as well as variable head, friction dominated and constant head systems are compared and recommendations given. We have had some discussions about these things and this article is good reading.
New breakers, transformers and earth-quakes, safety in drives and a few other articles make this issue well worth reading.
