Beschreibung

Since transmitting reactive power over long distances is not feasible, power factor correction capacitors are used to provide local reactive power compensation. This text provides engineers with a step-by-step approach to the fundamentals, capacitor applications, protection issues, and system impact based on practical installations involved in designing power system capacitors. The author describes the fundamentals of capacitors focused on the power factor correction, industry standards, capacitor specifications, protection of shunt capacitors, maintenance of capacitor banks, and system impact issues. This is a valuable tool for any power system engineer in industry, utilities, consulting, and practical power system evaluation.

Pressestimmen

"One of this book's several virtues is that higher mathematics is resorted to only as necessary, with numerous worked examples amply demonstrating the calculations involved. Another is the extensive bibliographyall too often, users suppose that capacitors, as simple static devices, may safely be neglected. Dr. Natarajan strongly refutes that, offering a useful checklist of symptoms, diagnoses, and remediesthis book is a valuable reference as the only current work of its kind." - Electrical Apparatus, July 2005
