ABSTRACT: This is a new technique for the protection of transmission systems by using the global positioning system (GPS) and fault generated transients. In this scheme the relay contains a fault transient detection system together with a communication unit‚ which is connected to the power line through the high voltage coupling capacitors of the CVT. Relays are installed at each bus bar in a transmission network. These detect the fault generated high frequency voltage transient signals and record

1. Introduction 1.1 Background of this report Due to inadequate power generation in several power plants load shedding started early this year. Dhaka city experiences frequent power outage in the last few years and the situation is likely to continue. People living in Mirpur and Old part of Dhaka are experiencing the worst outage in Dhaka. Frequent power cut is causing immense suffering in public life. Production of garments factory is running low in the city. Office work is severely disrupted

TECHNOLOGY ABSTRACT [pic] Transmitting power at high voltage and in DC form instead of AC is a new technology proven to be economic and simple in operation which is HVDC transmission. The HVDC (High Voltage Direct Current) technology is used to transmit electricity over long distances by overhead transmission lines or submarine cables. It is also used to interconnect separate power systems. A further development in this technology is HVDC light where HVDC

A Power Line Communication Explained (1984) Challenges and Technologies Abstract This paper reviews the sources of attenuation‚ noise and distortion encountered when communicating over AC power wiring. Various technologies which have been used to address these challenges‚ such as spread spectrum and digital signal processing‚ are then examined in light of the known channel conditions. Introduction While the idea of sending communication signals on the same pair of wires as are used for

The hydel power development in Kerala began with the commissioning of Pallivasal hydro electric project in 1940. Next few decades saw the progressive developments of various schemes. The Paruthipara substation is the oldest substation in Trivandrum. There are 4 main feeders into this substation .it consists of a upper yard and a lower yard. The upper yard has the 2 feeders from Pothencode substation. These are 110kv feeders. The power basically comes from the Sabarigiri power project via Edamon

breaker power‚ chain sprocket‚ generator. I. INTRODUCTION This paper attempts to show how energy can be tapped and used at a commonly used system‚ the road speed breakers. The number of vehicles passing over the speed breaker in roads is increasing day by day. A large amount of energy is wasted at the speed breakers through the dissipation of heat and also through friction‚ every time a vehicle passes over it. There is great possibility of tapping this energy and generating power by making

Power (light) helps in our day to day activities. Basically it helps to ensure the smooth running of things and to make life easier. It is used to power electrical appliances‚ in homes‚ schools and industries. It is a major part of production processes. But with power outage‚ production will be
