Management of Available Power in Substation Transformers Based on Reliability
A method for estimating the maximum power obtainable from a distribution transformer is described in this article. This estimate is made on the basis of the estimated value of the future load, current temperature values measured at different points and also the factor of transformer reliability. Also developed is a system to provide means of controlling the transformer overload especially in the times of peak load.

There is an increasing need for fault tolerance capabilities in logic devices brought about by the scaling of transistors to ever smaller geometries. This paper presents a hypervisor-based replication approach that can be applied to commodity hardware to allow for virtually lockstepped execution. It offers many of the benefits of hardware-based lockstep while being cheaper and easier to implement and more flexible in the configurations supported. A novel form of processor state fingerprinting is also presented, which can significantly reduce th ....etc

Abstract—
Industry of street lighting systems are growing
rapidly and going to complex with rapid growth of industry and
cities. To control and maintain complex street lighting system
more economically, various street light control systems are
developed. Nevertheless most of developed systems have some
drawbacks.
So we are going to develop new light control system which can
overcome old systems drawbacks. We surveyed various street
light control systems and analyzed its characteristics. Through
these efforts, we found that c ....etc

The switched varactor for high power RF signals is described in this article. This varactor can perform tuneable capacitor operations up to 10 GHz frequencies. The RF micro-electro-mechanical systems (MEMS) has become an atractive area of research in the recent. Devices like tuners, antenna beam forming networks and reconfigurable filters all will benefit from this.

Design principles
In the case of RF MEMS which depend on the electrostatic actuation have a a small air gap in the micrometer range between their movable membrane and ....etc

Power System Reliability Analysis with Distributed Generators





Introduction

The economic and social effects of loss of electric service have
significant impacts on both the utility supplying electric energy and the end
users of electric service. The cost of a major power outage confined to one
state can be on the order of tens of millions of dollars. If a major power
outage affects multiple states, then the cost can exceed 100 million dollars.
The p ....etc

ABSTRACT
A distribution system is the part of an overall power system which links the bulk system to the individual customers. The primary goal of any distribution system is to supply reliable and quality power to the customers economically. The reliability indices like SAIFI, CAIDI, and ASAI and so on are very important performance indices which need to be satisfied from customer point of view. Calculation of these indices is essential to assess the reliability of a dist ....etc
