A transformer performs many functions such as voltage transformation, isolation, and noise decoupling, and it is an indispensable component in electric power distribution systems. A distribution transformer has consisted of a configuration of iron or steel cores and copper/aluminum coils, with mineral oil serving as both coolant and dielectric medium. Inherent in this type of construction are regulation, significant weight, losses, environmental concerns, and power quality issues. A new kind of distribution transformer is proposed ....etc

ABSTRACT
Wide band Sigma-Delta PLL modulator is based on PLL fractional N synthesis techniques along with Sigma-Delta modulation to randomize fractional N spurs. A modified Sigma-Delta function allows for suppression of Sigma-Delta noise at low frequencies & hence allows wider bandwidth. This is achieved using a fractional-N PLL architecture. They are capable of synthesizing frequencies at channel spacings less than the reference frequency. This helps to increase the reference frequency & hence reduces PL ....etc

ABSTRACT
As leading companies continue to look for innovative ways to reduce costs and increase in production, and labour is one of the main constrain of present time, rail wagon unloading systems are generating more attention. Our project gives a brief overview of unloading coal by BOBRN (Bottom open broad gauge rail) type wagon using track hoppers instead of manual unloading.
