This paper gives a case of large Sub-Station Clean Development Mechanism (CDM) Project to analyze CDM project’s influence on India’s Sustainable Development. SF6 gas is being extensively used in circuit breakers. SF6 gas has the highest Global warming potential which is 23900 times of Carbon Dioxide. Extensive Survey of SubStation using SF6 circuit breaker has been done in a sample state of Ind...

The purpose of this project is to acquire the remote electrical parameters like Voltage, Current and Frequency and send these real time values over GSM network using GSM Modem/phone along with temperature at power station. This project is also designed to protect the electrical circuitry by operating an Electromagnetic Relay. This Relay gets activated whenever the electrical parameters exceed t...

The purpose of this paper is to acquire the remote electrical parameters like Voltage, Current, and Frequency from Smart grid and send these real time values over GSM network using GSM Modem/phone along with temperature at power station. This project is also designed to protect the electrical circuitry by operating an Electromagnetic Relay. The Relay can be used to operate a Circuit Breaker to ...

A two-dimensional compressible magnetohydrodynamic (MHD) computational model has been developed to study the effect of gassing material on air arc behavior in low voltage circuit breaker. The properties of arc plasma and the electric, magnetic and radiative phenomena have been taken into account in the model. Based on the model, steady state solutions have been performed to study the effect of ...

Aiming to better reflect features of machinery vibration signals of high-voltage HV circuit breaker (CB), a new method is proposed on the basis of energy-equal entropy of wavelet packet(WP). First of all, three-layer wavelet packet decomposes vibration signal, reconstructing 8 nodes of signals in the 3rd layer. Then, the vector is extracted with energy-equal entropy of reconstructed signals. At...

With the development of flexible low frequency transmission technology following improvement offshore wind power transmission, it is great significance to investigate operation adaptability main equipment especially under conditions. A comparative study was performed in present work discuss dynamic performance a 252 kV/50 kA puffer-type circuit breaker influenced by system operational frequency...
