Digitally Modulated Carrier Amplitude



•When measuring the amplitude of a digitally modulated carrier, make certain you are measuring its average power level

•Use test equipment that performs automated measurements, rather than trying to make error-prone manual measurements that require bandwidth, IF filter, log amplifier and detection corrections

INTRODUCTION
Protective relaying is an integral part of any electrical power system. The fundamental objective of system protection is to quickly isolate a problem so that the unaffected portions of the system can continue to function. The flip side of this objective is that the protection system should not interrupt power for acceptable operating conditions, including tolerable transients.
• The choice of protection depends upon several aspects such as type, rating of the protected equip ....etc

EFFECTS OF VOLTAGE SAGS, SWELL AND OTHER DISTURBANCES ON
ELECTRICAL EQUIPMENT AND THEIR ECONOMIC IMPLICATIONS



ABSTRACT

Poor power quality has come to stay in most parts of the
world. In most part of Africa, especially in Nigeria, it is
almost normal not to have good clean power free from
disturbances. If power equipment and loads could talk or
express feelings, I am sure they would have made a big
protest against the great injustices imposed on them. A
survey was carried out amongst 15 multi-nation ....etc

ABSTRACT:
The economics of generation of electrical energy and the huge demands of power in the modern times require creation bigger power plant . These may be hydro , thermal , atomic etc . The transmission network is inevitable . large and high voltage transmission lines are necessary to transmit huge blocks of power from the source of generation to load centers . In b/w the power plant and ultimate consumer a number of transmission and switching stations have to be created . This is done by SUBSTATION . This mini ....etc

EQUIPMENT OF VEMIGIRI 400/220 KV SUBSTATION


INTRODUCTION
The 400/220KV sub station, Vemagiri was commissioned at16:35 hrs on 10/09/2005 by energising the bus 1 from 400KV Kalapaka-Vemagiri circuit-1. It is located near to NH-5 opposite to Andhra Bhoomi press, at Vemagiri village in Kadiyam mandal, East-Godavari District which is at a distance of 10KM from the RJY Railway station. The construction of the project was taken ....etc

Abstract:
The keys to successful motor operation include a total understanding of the application, then choosing the proper type of motor for the application. This must then be followed by the proper installation – mounting, coupling, and a total understanding of the motor surroundings or environment. Of course, for continued success proper maintenance of the motor must also be performed. Many problems could be avoided if the application and environment were understood, while others may be caused by a changin ....etc

Over the river and through the woods was more dangerous back when cars had crummy bias-ply tires, rear-wheel drive and ordinary brakes. So, tonight you feel confident driving home through several inches of freshly fallen snow after a sump ....etc

ABSTRACT

An expert system for personal computer troubleshooting, developed as part of MCA 6th semester Course project work, National Institute of Technology, Calicut, is presented. It is implemented on a personal computer. The proposed system includes many characteristics of an expert system because it can be expanded easily by adding new information to its knowledge base or by changing its existing information. The basic idea behind this expert system is to provide a non-expert with the necessary information and interaction ....etc
