  • FSW Fuse-Switch-Disconnectors
    Motors | Automation | Energy | Transmission & Distribution | Coatings FSW Fuse-Switch-Disconnectors www.weg.net Fuse-Switch-Disconnectors The FSW Fuse-Switch-Disconnectors, developed according to International Standard IEC 60947-3 and bearing CE certification, are applied in electric circuits in general so as to provide the disconnection and protection against short circuits and overloads by means of NH blade contact fuses. In order to ensure a long lifespan, the FSW Fuse-Switch-Disconnectors are manufactured with reinforced thermoplastic materials and flame retardant. Additionaly, they feature contacts with silver coating, providing low power losses. Safety and Simplicity WEG switch-disconnector has several characteristics which aim at increasing security for operation and maintenance of the equipment, simplifying diagnoses and fuse replacement: g The switch-disconnector allows checking the state of the fuses through a transparent cover, besides featuring small openings which allow making electrical measurements without interrupting the operation. g As per IEC 60947-3, the switch-disconnector can perform the non- frequent opening under load. The FSW series has arc chambers for the extinction of the electric arc and disconnects all the phases together, ensuring full insulation between the load circuit and power supply. g In the opening of the switch-disconnector, the fuses remain fixed to the cover, preventing their drop or accidental contact between the energized parts. Furthermore, the cover is totally removable, allowing simple fuse replacement in a simple and safe area out of the electrical panel. g The switch-disconnectors also feature a built-in auxiliary contact in order to indicate when they are open or not properly closed.

    Principles of Shunt Capacitor Bank Application and Protection Satish Samineni, Casper Labuschagne, and Jeff Pope Schweitzer Engineering Laboratories, Inc. Presented at the 64th Annual Georgia Tech Protective Relaying Conference Atlanta, Georgia May 5–7, 2010 Previously presented at the 63rd Annual Conference for Protective Relay Engineers, March 2010, and 9th Annual Clemson University Power Systems Conference, March 2010 Originally presented at the 36th Annual Western Protective Relay Conference, October 2009 1 Principles of Shunt Capacitor Bank Application and Protection Satish Samineni, Casper Labuschagne, and Jeff Pope, Schweitzer Engineering Laboratories, Inc. Abstract—Shunt capacitor banks (SCBs) are used in the electrical industry for power factor correction and voltage support. Over the years, the purpose of SCBs has not changed, but as new dielectric materials came to market, the fusing practices for these banks changed from externally fused to internally fused, fuseless, and finally to unfused [1]. This paper gives a brief overview of the four most common types of SCBs. What are the differences between them? Which is the best one to use? What type of protection is best suited for each bank configuration? The paper provides a quick and simple way to calculate the out-of-balance voltages (voltage protection) or current (current protection) resulting from failed capacitor units or elements. While the identification of faulty capacitor units is easy with an externally fused bank, it is more complex with the other types of fusing, making maintenance and fault investigation difficult. This paper presents a novel method to identify the faulted phase and section in capacitor banks. Fig. 1. Four most common capacitor bank configurations I.
