Case Studies

Due to the continuous increase of power handling capacity, increase in network voltages, continuous design improvements and operational requirements of switchgear. In this article, short circuit test duty requirements of 12kV circuit breaker are discussed. By Yugal Agrawal

In this article a basic duty of a “Controlled Switching Device” in back to back switching of a shunt capacitor banks has been explained. The Transients developed are very high in nature and are very injurious to the circuit breaker used for this duty. A case study, highlighting the need for implementing such device for back to back switching of shunt capacitor banks is also described... - Er K K Murty
