ABSTRACT
This paper describes the application of two relatively new diagnostic techniques for the determination of insulation condition in aged transformers. The techniques are (a) measurements of interfacial polarization spectra by a DC method and (b) measurements of molecular weight and its distribution by gel permeation chromatography. Several other electrical properties of the cellulose polymer were also investigated. Samples were obtained from a retired power transformer and they were ana..............etc

COST EFFECTIVENESS OF MINERAL WOOL INSULATION Vs PERLITE INSULATION
PROJECT REPORT
Submitted by
DIPU.K.SHAJI GITHU BABU VARUN KUMAR. T.K VIMAL MENON
ABSTRACT
The main objective of this project is to make the cost effectiveness analysis of the system of the thermal insulation of the pipe lines in petrochemical plant which carries steam. In a chemical plant maintaining temperature of fluids in different pipe lines assume greatest importance as each process is performed at particular temperature.
The project work was car..............etc

INTRODUCTION
The major concern in the selection of the proper insulation for a cryogenic system is the reduction in the heat leak.
The insulation strategy is to minimize the radiative heat transfer, minimize the convective heat transfer, and introduce a minimum of solid conductance media
MODES OF HEAT TRANSFER
Solid conduction

Gas convection and conduction

Radiation

FACTORS CONSIDERED IN THE SELECTION OF THE INSULATION
Thermal Effec..............etc

Power Factor Correction of Linear and Non-linear Loads Employing a Single Phase Active Power Filter Based on a Full-Bridge Current Source Inverter Controlled Through the Sensor of the AC Mains Current
Abstract:
In the last years the number of non-linear loads has been increasing rapidly. This non-linear load had drawn a current form the AC Mains with harmonic components, leading to low power factor, low efficiency, interference by the EMI, among others. A classic solution is the use of passive filters, which ..............etc
