FIBER OPTIC SENSORS
Optical fiber sensor: A sensor that measures a physical quantity based on its modulation on the intensity, spectrum, phase, or polarization of light traveling through an optical fiber.

To measure physical parameters such as strain, temperature, pressure, velocity, and acceleratio ....etc

ABTRACT:
The electricity sector is facing enormous challenge in most countries around the world due to deregulation and growing demand on power. Efficient supply of electricity in restricted environment conditions has added more pressure on power utilities to operate increasingly on commercial terms. Therefore, utilities must develop greater flexibility and security in terms of supply and distribution of electricity in the most effective and environment-friendly way possible. Undergro ....etc

Effect of HVAC System on Neighbouring Pipelines and
Communication Cables

A. Abu-Siada, M. Bahram
Curtin University of Technology, Australia

Abstract—
Sharing of common corridors between power lines, pipelines and telecommunication lines is becoming a familiar scene. High levels of voltages can be induced in services which run in parallel or in close vicinity of high voltage AC transmission lines, in particular during a fault on the transmission line. These hazardous voltages can af ....etc

INTRODUCTION TO SMALL SCALE INDUSTRY
THE SSI (SMALL SCALE INDUSTARY) today is immense for the growth of the country. Small scale industries are the industries which are run with the help of their labours and which also use some simple machine and power.
The investment scale in this industry from 50 lakh to 1 crore for fixed assets. Irrespective number of worker engaged is small scale industry unit.
In India these type of industries are permuted to meet with the problem of excess population and unemployment so the ....etc

ABSTRACT
Urban electrical power systems with steep demand increase need easily located solutions with short lead time from decision to transmission. While AC cable solutions can offer sufficient power ratings, the problems of load controllability and short circuit power increase with every added circuit. These problems may be countered with Voltage Source Converter (VSC) based technology using Cables for transmission, such as HVDC Light. This technology offers up to 500 MW per station with small footprint, ideal for in feed to city ....etc

ADSS Cables on EHV, HV, MV Transmission Lines

The installation of fiber-optic cables on transmission towers that support EHV, HV, MV transmission lines provides an effective communications system on electric networks. Electric utilities have used fiber-optic cables for several years to provide a communications page link between neighboring substations or between substations and the control desk. It opens new perspectives for the future to create “all optical” Internet and ot ....etc
