As the size of motors being manufactured increases, the issue of motor cooling becomes more and more critical. The high ambient temperature and the severe corrosive environment of many locations in the Chemical, Oil & Gas (COG) industry, in addition…
Transformers are used in Power systems to transform (step-down) voltages while maintaining the same frequency. Electrical Engineers designing power systems for Liquefied Natural Gas (LNG) or Petrochemical facilities typically use two-winding…
This paper concentrates on the methods and benefits of using adjustable frequency drives (AFDs) on synchronizing applications (primarily medium voltage): the use of one drive for separately starting and synchronizing multiple motors to a constant…
There are two common flow regulation methods for crude oil pipeline, regulating valve opening and frequency converter speed regulation. The basic principle of frequency converter speed regulation and the principle of frequency converter power-saving…
